Bacterial and viral infections can cause similar symptoms such as coughing, sneezing, fever, inflammation, vomiting, diarrhea, fatigue, and cramping -all of which are ways the immune system tries to rid the body of infectious organisms.
Viruses are smaller than bacteria and require living hosts such as people, plants or animals to multiply; otherwise, they can't survive. When a virus enters your body, it invades some of your cells and takes over the cell machinery, redirecting it to produce the virus.
Viruses cause a number of diseases in humans. Some diseases include: Ebola, smallpox, the common cold, chickenpox, influenza, shingles, herpes, polio, rabies and AIDS.
How to Prevent Viral Infections
Avoid touching bodily fluids from other people such as blood, saliva, and semen. Direct contact with these fluids are often the cause ofbacterial and viral infections, such as hepatitis and AIDS.

and the kitchen sink.

as pay phones and door handles.
Avoid shaking hands with anyone who has a cold. To be extra cautious, wash your hands after you shake hands with anyone just in
case their hands carried a bacterial infection. Also avoid touching your eyes or nose after shaking hands with someone.
Avoid touching your eyes or nose with unwashed hands.
Cook and cool down food as quickly as possible to prevent bacterial infection. Perishable food should not be left at room temperature any longer than necessary to prevent bacteria from multiplying on the food.
