Primary, secondary, and tertiary sources. When searching for information on a topic, it is important to understand the value of primary, secondary, and tertiary sources.Primary sources allow researchers to get as close as possible to original ideas, events, and empirical research as possible.ertiary resources often provide data in a convenient form or provide information with context by which to interpret it. The distinctions between primary, secondary, and tertiary sources can be ambiguous.
As you might think, bacterial infections are caused by bacteria, and viral infections are caused by viruses. Perhaps the most important distinction between bacteria and viruses is that antibiotic drugs usually kill bacteria, but they aren't effective against viruses.
Antibiotics treat bacterial infections and are ineffective for the treatment of viral infections. Sometimes drugs called antiviral drugs may be used to help treat certain types of viral infections. Antiviral drugs help to minimize the severity of a viral infection.Depending on the type of viral infection and the presence of complications, a wide variety of other treatments may be needed.iral diseases can be very difficult to treat because viruses live inside the body's cells where they are protected from medicines in the blood stream. Researchers developed the first antiviral drug in the late 20th century.
