Figure 4. Weekly hMPV case counts and symptomatic incidence rate from 2011–2016. A) Weekly count of hMPV cases in the NPICS cohort from 2011­–2016. B) Weekly symptomatic incidence rate for hMPV cases in the NPICS cohort within a 95% confidence interval from 2011–2016. Yellow bars indicate the ascending phase length for each outbreak and the subsequent estimated mean effective reproductive number based on a 5-day serial number. C) Weekly symptomatic incidence of hMPV cases causing Acute Lower-Respiratory Infection (ALRI) in the NPICS cohort within a 95% confidence interval from 2011–2016.
