   Bacterial Infection. Bacterial infections are diseases that can affect your skin, lungs, brain, blood and other parts of your body.

   Is fever a bacterial or viral disease?

   • Fever is common in both bacterial and viral gastroenteritis. High fever is commonly present in many bacterial causes (e.g. Shigella, Salmonella, Shiga toxin-producing E. coli). Fever is often absent or low-grade in other diseases (e.g. enteropathogenic E. coli, cholera). Other febrile conditions cause diarrhoea and need to be differentiated.

   Can a viral infection cause a bacterial infection?

   • Sometimes, viral illnesses lead to bacterial infections. For instance, a cold can cause fluid to build up in your respiratory system, and fluid in your ear can become infected with bacteria. In that case, an antibiotic will help clear the bacterial infection. But it won't do anything to the virus.
