The Centers for Disease Control and Prevention (CDC) says that several states have recently reported an unusual finding in some influenza patients this season: parotitis, or swelling of the salivary glands.

The median duration of colonization with community-based methicillin-resistant Staphylococcus aureus (MRSA) in ambulatory patients is 21 days, shorter than the previously thought duration of 6 to 9 months, and treatment with clindamycin is associated with more rapid clearance of the infection, say findings of a study published yesterday in Clinical Infectious Diseases.
Oseltamivir (Tamiflu) taken within 24 hours of flu symptom onset shortened the duration of all symptoms by 56%, but had no effect on household flu transmission or viral shedding, according to a study yesterday in the Journal of Infectious Diseases.
Influenza seems reluctant to release its grip on the United States, as most measures of flu activity showed little change last week, according to today's update from the Centers for Disease Control and Prevention (CDC).
Analysis finds a significant reduction in symptom duration, risk of hospitalization, and likelihood of complications.
The Northern Hemisphere continues to see high levels of influenza A (H3N2), especially in North America and northwestern Europe, according to a Jan 26 World Health Organization (WHO) report.

Not surprisingly, the entire Northern Hemisphere is seeing increasing influenza activity, with H3N2 most common, but unfortunately in an antigenically drifted strain not well matched to the strain in this year's vaccine, according to an update yesterday from the World Health Organization (WHO).
