transmission method similar to needle-sharing 結果共1筆

A pivotal study reveals that dengue fever can rapidly spread through a transmission method similar to needle-sharing in infectious diseases like HBV, HCB, and HIV. The study, conducted by Taiwan’s National Health Research Institutes in collaboration with the Department of Health and Kaohsiung City Government, analyzed the timing of infections during the 2015 outbreak. They found that in 85% of household cases, symptoms occurred within three days of each other, contradicting the previously believed incubation period for virus transmission. Using animal models, researchers confirmed that when mosquitoes bite an infected animal and then promptly bite another, the virus can transfer via the mosquito’s proboscis, bypassing the once-considered essential eight-day extrinsic incubation period. This finding explains the rapid spread of the 2015 dengue epidemic in Taiwan and raises concerns for the recent spike in cases. The study, published in the esteemed journal eBiomedicine, a Lancet subsidiary, in August 2023, also involved international researchers from the University of California, Nagoya University, Tsinghua University, and National Taiwan University.
