美國研究發現，流感病毒的傳播與空氣濕度有密切關係。


俄勒岡州大學研究人員發現，當絕對濕度較低時，流感病毒存活期較長，傳染率也比較高；但當絕對濕度高時，流感病毒存活期較短，傳染率較低。


研究員說，這項發現有助於解釋流感爆發為何會有季節性高峰期。專家說，適當增加空氣濕度是必要的，但是也要留意濕度過高，可能會助長霉菌滋生。

Absolute humidity modulates influenza survival, transmission, and seasonality.

Shaman J, Kohn M.

Influenza A incidence peaks during winter in temperate regions. The basis for this pronounced seasonality is not understood, nor is it well documented how influenza A transmission principally occurs. Previous studies indicate that relative humidity (RH) affects both influenza virus transmission (IVT) and influenza virus survival (IVS). Here, we reanalyze these data to explore the effects of absolute humidity on IVT and IVS. We find that absolute humidity (AH) constrains both transmission efficiency and IVS much more significantly than RH. In the studies presented, 50% of IVT variability and 90% of IVS variability are explained by AH, whereas, respectively, only 12% and 36% are explained by RH. In temperate regions, both outdoor and indoor AH possess a strong seasonal cycle that minimizes in winter. This seasonal cycle is consistent with a wintertime increase in IVS and IVT and may explain the seasonality of influenza. Thus, differences in AH provide a single, coherent, more physically sound explanation for the observed variability of IVS, IVT and influenza seasonality in temperate regions. This hypothesis can be further tested through future, additional laboratory, epidemiological and modeling studies.

這個可以比較一下海島性國家跟大陸性國家的差異性，是否有差別吧？
