• In Oceania, influenza activity remained
low overall with a few detections of
influenza A viruses reported in Australia.
Influenza activity remained low in New
Zealand and the hospitalization rate for
SARI was low overall but increased in
children under five years due to
rhinovirus and RSV activity and
decreased in adults over 80 years of
age. In the Pacific Islands, ILI activity
overall was low or decreased except in
Samoa and the Marshall Islands.
• In South Africa, detections of influenza
• In temperate South America, influenza detections remained elevated in
A(H3N2) decreased and influenza
Argentina and Chile and low in Paraguay and Uruguay. In Argentina,
detection rates in ILI and pneumonia
influenza B was predominant followed by influenza A(H1N1)pdm09 and
surveillance remained at inter-seasonal
positivity remained at a high level unusual for this time of year though ILI
levels. There were few SARS-CoV-2 or
remained low and SARI was below the baseline. In Chile, influenza
RSV detections and the detection rate
A(H3N2) predominated and percent positivity and ILI rates decreased
for RSV in children under five years of
slightly but remained unusually elevated for this time of year with
age remained below the epidemic
positivity at a high level and ILI remaining at an extraordinary level. The
