10 Common Communicable Diseases and How to Prevent Them

Communicable diseases are illnesses caused by viruses, bacteria, fungi, and parasites that can spread from one person to another. These diseases can be mild or severe, and some can even lead to death if not treated properly.

In this article, we will discuss the 10 most common communicable diseases and how you can prevent them.

Influenza

Influenza, also known as the flu, is a respiratory illness caused by a virus. Symptoms of the flu include fever, cough, sore throat, body aches, and fatigue.

Tuberculosis

Tuberculosis (TB) is a bacterial infection that primarily affects the lungs. Symptoms of TB include coughing, chest pain, and difficulty breathing. TB is highly contagious and is spread through the air when an infected person coughs or sneezes. The BCG vaccine is available to prevent TB, and treating TB with antibiotics is important to prevent further transmission.

Hepatitis B
