Human Coronavirus-Associated Influenza-Like Illness in the Community Setting in Peru.

We present findings describing the epidemiology of non-severe acute respiratory syndrome human coronavirus-associated influenza-like illness from a population-based active follow-up study in four different regions of Peru. In 2010, the prevalence of infections by human coronaviruses 229E, OC43, NL63, or HKU1 was 6.4% in participants with influenza-like illness who tested negative for influenza viruses. Ten of 11 human coronavirus infections were identified in the fall-winter season. Human coronaviruses are present in different regions of Peru and are relatively frequently associated with influenza-like illness in Peru.
