Influenza, South Africa – Updated July 2020
Influenza has not been detected in any of the three sentinel surveillance programmes during this past month. Since the localised outbreak of influenza, A(H1N1) pdm09 and influenza B Victoria in the Western Cape Province in the beginning of the year, there has only been one detection of influenza A(H1N1) pdm09 in Gauteng Province from a Viral Watch surveillance site in the week ending 14 June.
Over the past 36 years, the influenza season has started in week 28 (week ending 12 July). This year, the various hygiene and physical distancing measures being implemented to reduce SARS-CoV2 virus transmission has likely played a role in interrupting influenza virus transmission.
Globally, influenza activity has been at lower levels than expected and to date, none of the southern hemisphere countries have reported any influenza activity.
