Trends of acute respiratory infection, including human metapneumovirus, in the Northern Hemisphere|7 January 2025|Others
Currently, in some countries in the temperate Northern hemisphere, influenza-like illness (ILI) and/or acute respiratory infection (ARI) rates have increased in recent weeks and are above baseline levels, following usual seasonal trends. Influenza activity is elevated in many countries in Europe, Central America and the Caribbean, Western Africa, Middle Africa, and many countries across Asia, with the predominant seasonal influenza type and subtype varying by location, typical for this time of year, except during most of 2020 and 2021, when there was little influenza activity during the COVID-19 pandemic (Figure 1). SARS-CoV-2 activity as detected in sentinel surveillance and reported to Global Influenza Surveillance and Response System (GISRS), along with wastewater monitoring from the reporting countries, is currently low in countries in the Northern hemisphere following prolonged high level activity during summer months in the Northern hemisphere. Where surveillance data is available, trends in RSV activity are variable by region with downward trends observed in most subregions of the Americas, except in North America where RSV activity has increased, and decreases have been observed in the European region in recent weeks. Some countries conduct routine surveillance and report trends for other commonly circulating respiratory pathogens, such as hMPV, and report such information on a routine basis. Some countries in the Northern hemisphere have reported increased trends, varying by virus, in recent weeks, typical for this time of year.
