Communicable Diseases

Some diseases in this world can spread from one person to another. These diseases can be very damaging to the physical and mental health of a person. Some of them can even cause death. There are several precautionary measures you can do to try to keep yourself safe. In this article, we’ll try to explain what are communicable diseases, how they spread, and how to avoid them.

How Communicable Diseases Spread

These diseases can spread from one person to another or from an animal to a person. These diseases can also spread through the surface of food, drink, or by inhaling small vapors spread by sneezing or cough of a sick person. The latest example we have recently experienced in our lives is covid-19 which can spread through almost all the sources we explained above.

How Dangerous they are

Some communicable diseases are not very serious and their signs can finish within a few days or weeks. However, some communicable diseases can be very dangerous. These dangerous diseases can cause long-term health issues and even death. They can get even more dangerous for those people who already have a weak immune system.

What people are most vulnerable to these diseases

The old people and even the young population with weak immunity are most vulnerable to communicable viruses. Those people who are already suffering from heart disease, diabetes, or blood pressure, etc are also in more danger. Moreover, people who do not vaccinate themselves can also suffer from dangerous communicable diseases like covid-19, polio, etc.

How to Avoid Them

Avoiding communicable diseases can be very difficult but possible. Keep your face covered if you are around an infected person. Avoid using any items of the person having a communicable disease. You should never leave these people alone, but try to keep a safe distance. Vaccinate yourself, your near and dear, and even your animals immediately. Avoid and do not throw litter in public places.

Types of Communicable Diseases

These are types of communicable diseases that include viruses, fungi, bacteria, and protozoa. When these communicable diseases spread in cities or entire countries then they are known as epidemic diseases and when they break out in different countries of the world, they become pandemic diseases.

Cure for Communicable Diseases

There are several vaccines for communicable diseases like polio, covid-19, Hepatitis A and hepatitis B, etc. The injection of these vaccines helps our immune system to create antibodies that can fight against these diseases to control and eradicate them when they attack. However, researchers are still trying to develop vaccines for diseases like malaria, HIV, and tuberculosis.


Our world has experienced several epidemics and pandemics. The notable of them is Covid1-9 that is still infecting people around the world. Covid-19 is a communicable disease that can spread very rapidly from one person to another. This virus is a pandemic disease that has spread across the globe. Despite the development of several vaccines, cases of covid-19 are still appearing in good numbers in different parts of the world.
