Infectious causes of fever of unknown origin.

A number of viral, parasitic an...

Following the recent decline in influenza epidemics, approximately half of excess winter deaths are due to coronary thrombosis. These peak about two days after the peak of a cold spell. Approximately half the remaining winter deaths are caused ...
