BACKGROUND Madagascar was one of the first African countries to be affected by the 2009 pandemic of influenza A virus subtype H1N1 [A(H1N1)pdm2009] infection. The outbreak started in the capital city, Antananarivo, and then spread throughout the country from October 2009 through February 2010. METHODS Specimens from patients presenting with influenza-like illness were collected and shipped to...

The global population has been exposed to the novel pandemic H1N1 influenza virus since mid March 2009, causing the expansion of respiratory illness around the world, including Thailand. To evaluate the antibody titers against human pandemic influenza (H1N1) in Thai people with influenza-like illness (ILI), 45 paired serum samples (acute and convalescent) were subjected to hemagglutination inhi...

munity influenza exposure, as measured according to the presence of ill household members. Frontline HCWs were defined as staff who worked in the emergency department , triage unit, or outpatient clinic and screened patients with suspected 2009 H1N1 influenza. In this hospital, all HCWs with suspected or confirmed 2009 H1N1 influenza have been required to report to the hospital's occupational h...

conclusions clinical signs and symptoms presented by patients infected with the influenza a h1n1 virus were similar to those described for seasonal influenza, although with more gastrointestinal disorders. results among the 232 enrolled cases, 126 patients (54.31%) were male and 106 patients (45.89%) were female. real time reverse rt-pcr test revealed that 18.1% of suspected children were posit...

background: in order to provide guidance on the efficient allocation of health resources when handling public health emergencies in the future, the study evaluated the h1n1 influenza prevention and control program in hubei province of china using cost-benefit analysis. methods: the costs measured the resources consumed and other expenses incurred in the prevention and control of h1n1. the assum...

A swine influenza outbreak occurred on a commercial pig farm in Thailand. Outbreak investigation indicated that pigs were co-infected with pandemic (H1N1) 2009 virus and seasonal influenza (H1N1) viruses. No evidence of gene reassortment or pig-to-human transmission of pandemic (H1N1) 2009 virus was found during the outbreak.

The rapidSTRIPE H1N1 test, based on a nucleic acid lateral-flow assay, has been developed for diagnosis of a swine-origin influenza A (H1N1) virus. This test is simple and cost-effective and allows specific detection of the S-OIV A (H1N1) virus from swab sampling to final detection on a lateral-flow stripe within 2 to 3 h.

We report a case of encephalopathy progressing to brain death in a pediatric patient with confirmed infection with novel influenza H1N1. Although neurologic dysfunction associated with H1N1 has been described, we believe this to be the first published report of brain death associated with H1N1 infection.

• In influenza-immune subjects, H1N1 influenza virus–containing immune complexes can activate platelets through FcgRIIA. • H1N1 can also activate platelets through thrombin, independently of FcgRIIA, pointing to a role of coagulation in influenza infection. Platelets play crucial functions in hemostasis and the prevention of bleeding. During H1N1 influenza A virus infection, platelets display a...
