Are bacterial infections contagious?

Answer

Bacterial infections can be contagious, and some of them are extremely dangerous. One bacillus, named Yersinia pestis, was responsible for causing a plague that spread from fleas to people, then from person to person, throughout Medieval Europe; it caused tens of millions of deaths. The Centers for Disease Control and Prevention advises that the Yersinia pestis bacteria last struck the United States between 1924 and 1925, and infected urban residents throughout Los Angeles, Ca.

Methicillin-resistant Staphylococcus aureus, also known as MRSA, is another bacterial infection that can be transmitted from person-to-person. Community-associated MRSA begins as a boil on the surface of the skin, from which infected material escapes and spreads to individuals in close contact. The Mayo Clinic identifies groups who are at particular risk, such as wrestlers, child-care workers, and residents who live in crowded conditions where frequent skin contact occurs. MRSA can also be passed in health care settings, such as dialysis clinics and nursing homes.

Every year, MRSA infects another 94,000 people, of which it kills 18,650. MRSA deaths outnumber HIV deaths in the United States. According to WebMD, "only" 16,000 people die from AIDS and its complications each year. Fortunately, many bacterial infections -- MRSA included -- can be prevented with normal hand washing. These preventative measures include using antibacterial soap and other hygienic precautions, such as alcohol hand rubs.
