(CIDRAP News) – Flu activity remained low in the Northern Hemisphere last week, with only a few countries, such as Costa Rica and Cameroon, reporting spikes in the number of cases, the World Health Organization (WHO) said today.

Costa Rica is the only tropical country in the Americas to report increasing numbers of cases, which are primarily influenza A/H3N2, the WHO said.
