Northern Hemisphere flu markers show little increase
The US flu season showed little sign of gaining steam last week, with many of the signals staying below their baselines, the Centers for Disease Control and Prevention (CDC) said today. One marker that rose was the percentage of respiratory specimens testing positive for flu, up from 3.9% the previous week to 6.2%. All 10 of the CDC's regions were below baseline levels for doctor's visits for flulike illness, and the percentage of deaths from pneumonia and flu dropped to 5.7%, putting it below the epidemic threshold. No pediatric flu deaths or variant swine influenza infections were reported. Three states—Iowa, Texas, and Wyoming—reported local geographic flu spread, two more than reported in the CDC's last update.

Meanwhile, the World Health Organization (WHO) said today that many Northern Hemisphere countries are reporting increasing numbers of flu detections, though none have crossed their seasonal thresholds. Some tropical countries are reporting active flu transmission, including Nicaragua and Costa Rica, where influenza B is the most commonly detected virus, the WHO said. Other countries include Sri Lanka, Nepal, and Thailand, where the 2009 H1N1 virus is slightly more common than influenza B.
