Feedback:
Infections can be transmitted from person-to-person through shared inanimate objects (fomites) contaminated with infected body fluids. An example of this mechanism of transmission would include the spread of the HIV and hepatitis B virus through the use of shared syringes by intravenous drug users. Infection can also be spread through a complex combination of source, portal of entry, and vector. Infection with hantavirus pulmonary syndrome is a prime example. This viral illness is transmitted from mice to humans by inhalation of dust contaminated with saliva, feces, and urine of infected rodents.
