Bacterial diseases are caused by coming in contact with certain types of bacteria. Depending on the type of disease, it can be spread through coughs and sneezes, contaminated food, or contact with infected people or animals.

Overview and Symptoms
Although most bacteria do not cause disease, those that do can cause illnesses that range from mild to severe. They can cause many kinds of symptoms, but common symptoms can include cough, body aches and fever, headache, nausea and vomiting or skin rashes. Common examples of bacterial infections include pneumonia, food poisoning and skin infections.  Often, your doctor can identify the likely cause of a bacterial infection by listening to your medical history. A blood or urine test can help confirm a diagnosis. In some cases, a biopsy of affected tissue may be required.


Many bacterial infections are treated with antibiotics. Rest, hydration and over-the-counter medications can help reduce the effects of some symptoms.
