Increased hand washing reduces influenza virus surface contamination in Bangkok households, 2009-2010

Increased hand washing reduces influenza virus surface contamination in Bangkok households, 2009–2010

Within a hand-washing clinical trial, we evaluated factors associated with fomite contamination in households with an influenza-infected child. Influenza virus RNA contamination was higher in households with low absolute humidity and in control households, suggesting that hand washing reduces surface contamination.

Findings from a household randomized controlled trial of hand washing and face masks to reduce influenza transmission in Bangkok, Thailand

BACKGROUND Evidence is needed on the effectiveness of non-pharmaceutical interventions (NPIs) to reduce influenza transmission. METHODOLOGY We studied NPIs in households with a febrile, influenza-positive child. Households were randomized to control, hand washing (HW), or hand washing plus paper surgical face masks (HW + FM) arms. Study nurses conducted home visits within 24 hours of enrollme...

Epidemiology of seasonal influenza in Bangkok between 2009 and 2012.

INTRODUCTION This study investigated influenza activity in Bangkok, Thailand between June 2009 and July 2012. METHODOLOGY Real-time reverse transcription polymerase chain reaction (RT-PCR) was performed to detect influenza viruses among patients with influenza-like illnesses. RESULTS Of the 6417 patients tested, influenza virus infection was detected in 42% (n = 2697) of the specimens. Infl...

Shedding and transmission of novel influenza virus A/H1N1 infection in households--Germany, 2009.

Essential epidemiologic and virologic parameters must be measured to provide evidence for policy/public health recommendations and mathematical modeling concerning novel influenza A/H1N1 virus (NIV) infections. Therefore, from April through August of 2009, the authors collected nasopharyngeal specimens and information on antiviral medication and symptoms from households with NIV infection on a ...
