Causes and Symptoms of Infectious Diseases
Bacterial, viral, fungal, or parasitic infections that cause sickness. A wide range of species call our body home. They are typically benign or even helpful. But in some situations, some bacteria can make people sick. It is possible for some infectious diseases to transmit from one person to another and are contagious. Numerous diseases can be carried by insects and other animals. Others can be acquired by ingesting contaminated food or water, or by being exposed to environmental organisms. Common signs and symptoms of infection include fever and tiredness, though they might differ depending on the organism that is causing the infection.
