What are secondary bacterial infections?

Secondary bacterial infections are bacterial infections that occur in individuals that have already been diagnosed with another infection. For example, someone may be sick with the flu but symptoms seem to last longer than they should. Pneumonia, ear infections, and sinusitis may be the result of secondary bacterial infections. Indications that one of these may have occurred include prolonged symptoms-such as a viral infection running longer than the 14 days viruses tend to last- a higher fever than expected, and a fever that gets worse rather than improves after a few days of illness. Secondary bacterial infections of the skin may occur in lesions caused by scabies, eczema, poison ivy, or other conditions.
