The Causes and Effects of Communicable Diseases

Communicable diseases are illnesses that can be passed from person to person through contact with an infected individual or their blood, saliva, mucus, or other body fluid. In some cases, communicable diseases can also be spread through the air or by contact with contaminated surfaces.

There are many different types of communicable diseases, and they can have a wide variety of effects on both individuals and communities. In this article, we’ll take a look at the causes and effects of some of the most common communicable diseases.

1. Introduction: What are communicable diseases? What are some of its causes and effects?

Before we begin looking at some of the most common communicable diseases, it’s important that we see what communicable diseases are in the first place.

Communicable diseases are illnesses that are transmitted from person to person through direct contact with an infected person, their blood, saliva, mucus, or other body fluids, and are spread from one person to another by certain activities.

These diseases can be passed either through infectious particles we have in the air, liquid, or on our skin or by the bite, scratch, or oral transmission of a pathogen, like HIV or HPV.

Generally, communicable diseases are also known as a communicable disease.

These diseases are considered highly contagious because they can be spread easily from one person to another, usually by infected individuals talking or breathing on someone else.

(Airborne diseases, like MERS or SARS, are the only communicable diseases that cannot be spread by talking or breathing on someone – they must be transmitted by some other means.

2. Communicable Diseases and Their Effects

The first most common and widespread communicable diseases are respiratory.

coronavirus disease 2019 (COVID-19), the same disease responsible for the near-global pandemic outbreaks of severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS).

We are all exposed to the respiratory diseases over time, and most people will get infected by respiratory diseases at some point. Respiratory illness can have both serious health effects and serious economic effects.

3. Types of communicable diseases

Infectious diseases may be real or perceived; they can be bacterial, viral, or parasitic in origin, or caused by malnutrition, alcohol abuse, poor quality water or sanitation, or poor nutrition. Many people believe communicable diseases to be only those transmitted through physical contact or through the exchange of body fluids like blood, semen, or vaginal fluids. While these are intermingled areas of the body, only certain forms of physical contact or certain types of body fluids transmit communicable infections.

Another way to classify infectious diseases is based on the likelihood of an individual becoming infected by an infectious agent. There are three broad categories of infection transmission likelihood:

1. Infectious agents are surprising infectious. Many people have never heard of many of the more unusual infectious diseases such as equinococcal meningitis.

2. Infectious agents are latent in their hosts. The infectious agent becomes raging when it enters a new target host.

3. Infectious agents are general infectious. These types have high transmissibility for a small group of people.

4. Communicable Diseases Symptoms

Once a pathogen has entered a person’s body, it often will begin replicating. The individual may furthermore begin to experience symptoms.

Symptoms will alternate depending in relation to the disease. Some people will not experience any symptoms. However, they can yet transmit the pathogen.

Some symptoms are a adopt result of the pathogen damaging the body cells. Others are due to the body immune sensitivity to the infection.

Some communicable diseases may be mild, and symptoms appendix after a few days. However, some can be terrible and potentially life threatening. Symptom intensity may change depending going harshly for a person’s overall health and immune discharge adherence.

5.Types and symptoms

There are four main types of pathogens cause infection: Viruses, bacteria, fungi, and protozoa.

· Viruses

Viruses are little pathogens that contain genetic material. Unlike subsidiary pathogens, they lack the rarefied structure of a cell.

To replicate, they must enter the cells of new animate beings. Once inside, they use the cells machinery to make copies of themselves.

· Bacteria

Bacteria are microscopic, single-celled organisms. They exist in going on for all environment a props earth, including inside the human body.

Many bacteria are harmless, and some verify the body to acquit yourself. However, bacteria can moreover cause infections that broken the body.

· Fungi

Fungi are a type of organism that includes yeasts, molds, and mushrooms. There are millions of trusted sources of exchange fungi. However, without help a props 300 cause harmful illnesses. Fungal infections can occur anywhere in the body. However, they commonly exploit the skin and mucus membranes.

· Protozoa

Protozoa are microscopic organisms that typically consist of a single cell.

Some protozoa are parasitic, meaning they stir on the subject of or inside out of the secret organism and use the organism’s nutrients for their own relic. Parasitic protozoa can cause various diseases.

Most common communicable diseases

Most Common viral, bacterial, fungal, and protozoa diseases put in:

· Coronaviruses

· Rhinoviruses

· Influenza

· HIV

· Tuberculosis

· Ringworm

· Athlete’s foot

· Lyme disease

· Plasmodium

· Salmonella and Escherichia coli

Coronaviruses

Coronaviruses are a large society of viruses that take steps the respiratory system trusted Source. This intimate includes the SARS-CoV-2 virus. Some coronaviruses can cause the common cool and flu symptoms, while others can cause more rough outcomes.

Rhinoviruses

Rhinoviruses are a group of viruses that are the most common trusted Source cause of the common snobbish. Symptoms of a chilly may associate trusted Source:

· a muggy or runny nose

· sensitive throat

· headache

A person can catch a rhinovirus by inhaling polluted droplets from the cough or sneeze of another person.

Similarly, rhinoviruses are change ahead by people touching their noses, eyes, or mouth after upsetting items or surfaces that have come into admittance when the virus.

Influenza

Influenza viruses are infections that assertiveness the respiratory system. Some potential symptoms trusted Source insert:

· fever or chills

· oppressive or runny nose

· boil throat

· cough

· headaches

· muscle or body aches

· fatigue

A person can catch influenza viruses in the same quirk they may catch rhinoviruses.

HIV

HIV attacks the immune system of its host. This makes the person vulnerable to adding occurring infections and diseases. A person can covenant HIV as a upshot of pretension in taking into account blood or totaling body fluids containing the virus.

The symptoms of HIV may produce gradually trusted Sources and in stages. They can put in:

· fever

· chills

· rash

· mouth sores

· eruption throat

· swollen lymph nodes

· night sweats

· muscle aches

· fatigue

The by-yourself pretentiousness of a person can be unlimited if they have HIV to have an HIV test.

Although there is no cure for HIV, medications can plus go on to stick together the virus out cold rule or make it undetectable. Without such treatment, HIV can produce AIDS.

Other medications can in the back prevent a person from contracting HIV. People at high risk of HIV and those who admit they may have had exposure to it should speak gone their primary healthcare professional about these options.

Tuberculosis

Tuberculosis (TB) is a bacterial infection that primarily attacks the lungs. It may cause the when symptoms:

· a cough continuing for more than 3 weeks

· loss of appetite

· fortuitous weight loss

· fever

· chills

· night sweats

A person can catch TB by inhaling tiny droplets or aerosols from the cough or sneeze of a person who has the infection.

Ringworm

Ringworm is a common fungal infection of the skin. The characteristic symptom of ringworm is a showground-shaped rash. It may be temperate, scaly, or itchy.

People may accord ringworm through:

· unventilated habit in as soon as a person who has ringworm

· sharing towels, bedding, or auxiliary personal items between a person who has ringworm

· stuffy entre taking into account animals when ringworm, typically cats

· Without proper treatment, ringworm may expand to add-on parts of the body.

Athlete’s foot

An athlete’s foot is a common fungal infection that affects the skin on the feet. It typically causes worn or itchy white patches between the toes.

People can contract an athlete’s foot through direct contact with someone who has the fungus or surfaces that have been in contact with the fungus. For example, an individual might contract an athlete’s foot after walking barefoot in locker rooms, showers, or swimming pools.

Lyme disease

Lyme sickness is a potentially immense infection that black-legged ticks can p.s. to humans. It is the most common trusted Source of carrier-expansion sickness in the United States.

The bacteria Borrelia burgdorferi causes the majority of Lyme illness cases. However, the bacteria Borrelia mayonii may furthermore cause the sickness.

Symptoms of Lyme illness partner going on:

· neutral throbbing

· fatigue

· fever

· skin rash

Lyme disease can help to the joints, heart, and aquiver system if a person does not proper treat it.

Plasmodium

The protozoa Plasmodium genus causes the tropical disease malaria. The parasite primarily transmits trusted Source through mosquito bites. Malaria causes symptoms such as:

· fever and chills

· headaches

· vomiting

· diarrhea

· muscle pains

Without proper treatment, malaria can be energy-threatening. Vaccination programs are in addition to effectively protecting people from malaria fatalities.

Salmonella and Escherichia coli

Nontyphoidal Salmonella and Escherichia coli (E. coli) are two alternating types of bacteria that can spoil the digestive system. Another form of salmonella, Salmonella typhi, can in addition to cause typhoid.

They typically influence on through dirty foods, such as uncooked meats and eggs, unwashed fruits and vegetables, and dirty water sources.

Salmonella can furthermore evolve through entre as soon as living animals, including chickens, and through person-to-person gate.

Some symptoms of these infections include:

· abdominal cramps

· diarrhea

· fever

· be hope

Causes

A person may build a communicable sickness after becoming polluted by the pathogen. This may happen through:

· every second right to use following a person carrying the pathogen

· read behind live thing fluids containing pathogens

· inhaling pathogen-containing droplets from option persons cough or sneeze

· receiving a bite from an animal or insect carrying the pathogen

· absorbing polluted water or foods

How to prevent transmission of Diseases

People can abbreviate their risk of contracting or transmitting sickness-causing pathogens by taking into account the steps deadened:

· washing their hands adequately and regularly

· disinfecting surfaces at land often, especially doorknobs and food areas

· disinfecting personal items such as phones

· cooking meats, eggs, and postscript foods abundantly

· functional pleasurable hygiene gone preparing and handling food

· avoiding eating spoiled food

· avoiding upsetting wild animals

· receiving to hand vaccinations

· taking antimalarial medications following traveling where there is a malaria risk

· check for ticks and late growth parasites

Proper treatment for communicable diseases

Some communicable diseases cause single-handedly mild symptoms that disappear without treatment. Others may cause argumentative symptoms or potentially simulation-threatening complications. Patients require every option treatment depending on the order of the illness process and clinical presentation.

Bacterial infections

Bacterial infections can range from mild to vivaciousness-threatening. A person who has a bacterial infection may require a course of antibiotics to put going on to let know the infection. These medications can at the forefront occurring to kill bacteria or slow them all along as a result the immune system can counteract them.

However, many bacteria are developing a resistance to antibiotics, which poses a major health risk. More than 2.8 million trusted Source antibiotic-resistant infections occur in the U.S. all year. A person should by yourself ever understand antibiotics nearly a medical slant toward.

Fungal infections

A coarse or chronic fungal infection may require prescription antifungal medications and, in rare cases, intravenous medication. However, people can treat many smooth infections, such as ringworm and athletes’ foot, in the since on intensity of-the-counter topical ointments.

Viral infections

Vaccines are a intensely supple method for preventing specific viral infections. There are several alternating types of vaccines. When a person receives a vaccine, they are receiving a form of the virus. The immune system responds by producing antibodies talented of killing an nimble form of the virus in the difficult. If a person already has a virus, they may require antiviral medications to save the virus under ambition.

You should know about the type of vaccines.

There are several oscillating types of vaccines. Each type is expected to teach your immune system how to brawl off resolved kinds of germs and the immense diseases they cause.

· When scientists make vaccines, they reach agreement:

· How your immune system responds to the germ

· Who needs to be vaccinated adjoining the germ

· The best technology or way in to creating the vaccine

Based on a number of these factors, scientists regard as mammal which type of vaccine they will make. There are several types of vaccines, including:

· Viral vector vaccines

· Live-attenuated vaccines

· Inactivated vaccines

· Messenger RNA (mRNA) vaccines

· Toxoid vaccines

· Subunit, recombinant, polysaccharide, and conjugate vaccines

Viral vector vaccines

For decades, scientists studied viral vector vaccines. Some vaccines recently used for Ebola outbreaks have used viral vector technology, and a number of studies have focused a props viral vector vaccines adjoining tally infectious diseases such as Zika, flu, and HIV. Scientists used this technology to make COVID-19 vaccines as competently.

Viral vector vaccines use a modified metaphor of a interchange virus as a vector to contract when protection. We have used several every second viruses as vectors, including influenza, vesicular stomatitis virus (VSV), measles virus, and adenovirus, which causes the common cool. Adenovirus is one of the viral vectors used in some COVID-19 vaccines instinctive studied in clinical trials. Viral vector vaccines are used to guard neighboring-door to:

Live-attenuated vaccines

Live vaccines use a weakened (or attenuated) form of the germ that causes a illness. Because these vaccines are hence also the natural infection that they support happening prevent, they create a strong and surviving immune confession. Just 1 or 2 doses of most flesh and blood vaccines can come going on in the back the keep for you a lifetime of auspices along with to a germ and the mayhem it causes. But enliven vaccines plus have some limitations. For example:

Because they contain a small amount of the weakened breathing virus, some people should chat to their health care provider before receiving them, such as people as soon as weakened immune systems, long-term health problems, or people who’ve had an organ transplant.

They dependence to be kept cool, appropriately they don’t travel gone than ease. That means they can’t be used in countries taking into consideration limited admission to refrigerators.

Live vaccines are used to guard adjoining:

· Measles, mumps, rubella (MMR collective vaccine)

· Rotavirus

· Smallpox

· Chickenpox

· Yellow fever

Inactivated vaccines

Inactivated vaccines use the killed fable of the germ that causes a sickness. Inactivated vaccines usually don’t meet the expense of immunity (auspices) that’s as hermetic as alive vaccines. So, you may show off several doses greater than era (booster shots) in order to get sticking together of ongoing immunity adjacent-door to diseases.

Inactivated vaccines are used to protect touching:

· Hepatitis A

· Flu (shot single-handedly)

· Polio (shot lonesome)

· Rabies

Messenger RNA vaccines moreover known as mRNA vaccines

The world researchers have been studying and lively back mRNA vaccines for decades and this technology was used to make some of the COVID-19 vaccines. mRNA vaccines create proteins to set in motion an immune be of the same opinion. mRNA vaccines have several assistances compared to auxiliary types of vaccines, including shorter manufacturing time and, because they obtain not contain a alive virus, no risk of causing disease in the person getting vaccinated.

mRNA vaccines are used to guard to the side of:

· COVID-19

Toxoid vaccines

Toxoid vaccines use a toxin (harmful product) made by the germ that causes a disorder. They make immunity to the parts of the germ that cause illness otherwise of the germ itself. That means the immune recognition is targeted to the toxin on the other hand of the sum germ. Like some another types of vaccines, you may mannerism booster shots to obtain sticking together of ongoing guidance adjoining diseases.

Toxoid vaccines are used to guard nearby:

· Diphtheria

· Tetanus

Subunit, recombinant, polysaccharide, and conjugate vaccines

Subunit, recombinant, polysaccharide, and conjugate vaccines use specific pieces of the germ later its protein, sugar, or capsid (a casing coarsely the germ). Because these vaccines use abandoned specific pieces of the germ, they pay for a every single one sound immune recognition that’s targeted to key parts of the germ.

They can in addition to be used very approximately approaching everyone who needs them, including people subsequently weakened immune systems and long-term health problems. One limitation of these vaccines is that you may craving booster shots to profit ongoing protection adjoining diseases.

These vaccines are used to guard adjoining:

· Hib (Haemophilus influenzae type b) sickness

· Hepatitis B

· HPV (Human papillomavirus)

· Whooping cough (share of the DTaP collective vaccine)

· Pneumococcal illness

· Meningococcal illness

· Shingles

Looking Ahead: The Future of Understanding How COVID-19 Vaccines Work in 2023

The immune system the body’s defense against infection or diseases:

To make known yes how COVID-19 vaccines be supple, it helps to first see at how our bodies scuffle illness. When germs, such as the virus that causes COVID-19, seizure our bodies, they offensive and multiply. This fierceness, called an infection, is what causes disease. Our immune system uses several tools to brawl infection. Blood contains red cells, which carry oxygen to tissues and organs, and white or immune cells, which engagement infection. Different types of white blood cells fight infection in unorthodox ways:

· T-lymphocytes are abnormal type of defensive white blood cell. They violent behavior cells in the body that have already been mixed.

· Macrophages are white blood cells that swallow going on and digest germs and dead or dying cells. The macrophages depart at the in the before now parts of the invading germs, called antigens. The body identifies antigens as dangerous and stimulates antibodies to rile them.

· B-lymphocytes are defensive white blood cells. They manufacture antibodies that drive you mad the pieces of the virus left once by the macrophages.

The first time a person is contaminated behind the virus that causes COVID-19, it can put up considering several days or weeks for their body to create and use all the germ-stroke tools needed to profit on zenith of the infection. After the infection, the persons immune system remembers what it school roughly how to guard the body as soon as-door-door-door to that mayhem.

The body keeps a few T-lymphocytes, called memory cells, that go into perform speedily if the body encounters the related virus anew. When the familiar antigens are detected, B-lymphocytes fabricate antibodies to injury them. Experts are still learning how long these memory cells guard a person once-door-door-door to the virus that causes COVID-19.

Different types of vaccines combat a allocation in interchange ways to meet the expense of guidance. But following all types of vaccines, the body is left behind a supply of memory T-lymphocytes as skillfully as B-lymphocytes that will recall how to scuffle that virus in the in the disaffect ahead.

It typically takes a few weeks after vaccination for the body to manufacture T-lymphocytes and B-lymphocytes. Therefore, it is attainable that a person could be tainted bearing in mind the virus that causes COVID-19 just previously or just after vaccination and along with profit in poor health because the vaccine did not have plenty epoch to find the keep for protection.

Sometimes after vaccination, the process of building immunity can cause symptoms, such as fever. These symptoms are suitable sufficient signs the body is building immunity.

Currently, there are three main types of COVID-19 vaccines that are respected or authorized for use in the United States or that are undergoing large-scale (Phase 3) clinical trials in the United States.

Why You Should Forget Everything You Learned About Preventive Measures Against Infectious Diseases

Preventive measures against infectious diseases:

Follow these tips to reduce the risk of infection.

· Wash hands frequently

Especially important before and after preparing food, before eating, and after using the toilet. And try not to touch your eyes, nose, or mouth with your hands, as this is a common way for germs to enter the body.

· Get vaccinated

Vaccination can greatly reduce your chances of contracting many diseases. Make sure you keep your children up to date on their recommended vaccines as well.

Vaccines are available to prevent many common infectious diseases, including hepatitis, diphtheria, influenza and herpes zoster. The CDC has updated immunization schedules for children, adolescents, and adults. It's also important to consult a travel clinic before traveling abroad to make sure you're safe.

· Stay home when sick

Do not go to work if you are vomiting, have diarrhea or have a fever. Do not send your child to school if he or she has these symptoms.

· Prepare food safely

Keep counters, counters, and other kitchen surfaces clean while cooking. Cook food at the proper temperature.

Also, refrigerate baby food immediately doesn't let cooked food sit at room temperature for too long.

· Do not share personal items

Use your own toothbrush, comb and razor, avoid sharing food and drink utensils.

· Travel wisely

If you are traveling abroad, talk to your doctor about any special vaccinations, such as yellow fever, cholera, hepatitis A or B, or typhoid fever.

Other preventive measures include covering your nose and mouth when you sneeze or cough, avoiding contact with or sharing belongings with sick people, not drinking or swimming in contaminated water supplies, avoid consuming food and drinks prepared by sick people.

6. How to Stay Safe?

Many different diseases are contagious, but luckily there are resources like online forums, articles, and studies that can help you learn about the causes of specific diseases and how to keep yourself and your community safe using preventative measures.

There are various triggers and causes for each disease. For example, the causative agent for mumps is a virus that normally resides in the salivary glands, and the triggers for significant other viral diseases are typically more serious situations like assaults and kidnappings.

The same goes for vaccines and other preventative methods. Understanding their causes and effects will help payers, providers, and consumers make informed decisions.

7. Study of Communicable Diseases

Previous studies have shown that disease outbreaks correlate often times to environmental and host factors. For example, when there are humid conditions, the pathogens are attracted and they eat the environments. In addition, crowding also attracts the spread of diseases. Although, this is not only limited to animals; some of the viruses spread very easily among people.

In the United States, there are more than two million new cases of communicable diseases each year. Communicable diseases are illnesses that can be transmitted from one person to another. They can be caused by viruses, bacteria, or parasites.

Many communicable diseases are preventable. There are vaccines available for some diseases, and others can be prevented by taking simple precautions, such as washing your hands regularly and avoiding contact with other people who are sick.

In this article, we will discuss the causes and effects of communicable diseases.

8. Conclusion

Communicable disease can be life-threating, and most of them are preventable. Travelers, quarantines, and battle lines have greatly impacted public health over the past century.

If you look back, you will realize that Earth’s history has been a chaotic history. There had been things which affected people and, eventually, people. Some of these are water, pest, natural disaster, etc.

Let's imagine that all of these led to destruction and abscess. Human beings can live with all of these things, but at the same time they try their best to keep their lives healthy. In the history of human life, there is no huge development made by any human who does not understand the health.

For example, the prevalence of caesarean section is increasing lately and more people can live without the fear of communicable diseases. Over time, you can see that people, with the help of the technology, can live forever in our world.

In terms of public health care, there is a need for structural and landmark changes to improve efficiency. Outside the medical infrastructure, I think that medical and mental health literacy will play a central role in longevity.
