Infectious Disease

Infectious diseases are caused by pathogenic microorganisms such as bacteria, viruses, parasites, or fungi that can be spread from person to person, through contaminated food or water, or by animal or insect bites.

The world is currently facing increasing concern over the spread of infectious diseases, especially in light of the ongoing COVID-19 pandemic.

There are many different types of infectious diseases, each caused by a specific pathogen.

Some of the most common include tuberculosis, malaria, hepatitis, influenza, and sexually transmitted infections (STIs) such as HIV/AIDS and syphilis.

Diagnosing an infectious disease usually involves laboratory tests to identify the causative pathogen and the severity of the infection.
