Answer

In temperate areas, the peak incidence of infection occurs during late winter and spring. Infection is transmitted via respiratory droplets, which can remain active and contagious, either airborne or on surfaces, for up to 2 hours. Initial infection and viral replication occur locally in tracheal and bronchial epithelial cells.
