Educational Pearls
-
A recently published study assessed the burden of respiratory viruses in a longitudinal cohort of children from 0 to 2 years of age
-
The children in the study received nasal swab PCR testing weekly to determine infectivity
-
They were also monitored for symptoms via weekly text surveys
-
The study differentiated between infection and illness by defining an acute respiratory illness (ARI) as fever ≥38°C or cough.
-
-
The median infectivity rate was 9.4 viral infections per child per year
-
The median illness rate was 3.3 ARIs per child per year
-
-
The most common etiological viruses isolated from the nasal samples were rhinovirus and enterovirus
-
Most infections were asymptomatic or mild
-
