Infectious diseases are illnesses brought on by bacteria, viruses, fungus, or parasites. Our bodies are home to a variety of creatures. In most cases, they’re innocuous or even beneficial. However, certain microbes can cause sickness under particular circumstances.

Fever and exhaustion are common signs and symptoms, which vary depending on the organism that is causing the illness. Mild infections may be treated with rest and home treatments, but more serious infections may necessitate hospitalisation.

Vaccines help prevent several infectious illnesses, such as measles and chickenpox. Handwashing often and thoroughly also helps to prevent you from the majority of infectious infections.

Some infectious illnesses are contagious and can be spread from one person to the next. Insects and other animals can spread several diseases. Others can be contracted by ingesting tainted food or drinking tainted water, or by being exposed to organisms in the environment.
