    • Caribbean: Influenza virus activity is increasing in the subregion with low RSV activity. In Jamaica SARI activity increasedInfluenza virus activity is increasing in the subregion with low RSV activity. In Jamaica SARI activity increasedwith co circulation of influenza A(H3N2) and B. In Saint Lucia, influenza-like illness is above the epidemic threshold withinfluenza A(H1N1)pdm09 virus circulating in recent weeks.

In Brazil, influenza activity increased slightly in recent weeks and inChile, SARI activity increased in comparison to previous seasons.
    • Global: In the temperate zone of the northern hemisphere, influenza activity appeared to decrease overall. In Europe,In the temperate zone of the northern hemisphere, influenza activity appeared to decrease overall. In Europe,influenza activity decreased in most countries, but increased ILI activity was reported in some countries. In Central Asia,influenza activity was low. In Northern Africa, decreasing influenza activity was reported in Tunisia. In Western Asia,influenza activity was low in most reporting countries. In East Asia, ILI and influenza activity returned to baseline levels. Intropical Africa, influenza detections were low in most reporting countries. In Southern Asia, increased ILI activity wasreported in Bhutan. In South East Asia, influenza activity decreased across reporting countries. In the temperate zones ofthe southern hemisphere, influenza activity remained at inter-seasonal levels. Worldwide, seasonal influenza A virusesaccounted for the majority of detections.
