Utafiti uliofanywa na Chuo cha Tsinghua cha Nchini China ikishirikiana na Kituo cha Kupambana na Magonjwa nchimi humo umebainisha virusi hivyo hubadilisha harufu ya binadamu na panya wanaowaambukiza Katika majaribio tofauti, wanasayansi hao walipata molekuli zenye harufu kwenye ngozi ya panya aliyeambukizwa dengue, inayotajwa kuvutia mbu, ambao huwauma na kubeba virusi kwa mwathirika mwingine na kutoa jibu kwa sababu za magonjwa hayo kuenea kwa kasi Inaaminika maambukizi ya Dengue hufikia milioni 400 kila mwaka, huku Zika ikiripotiwa katika nchi 86 duniani ...................................................... Zika and dengue fever viruses alter the scent of humans and mice they infect, research, published by Cell, suggests. This makes them more attractive to mosquitoes, which then bite them and carry the viruses to the next victim. Spread in tropical areas, dengue causes fever, rashes and painful aches and can be fatal. Zika can cause birth defects, if pregnant women infected, but most adults have mild or asymptomatic cases and usually recover in a few days. Scientists at several Chinese labs, including the Chinese Centre for Disease Control and Prevention and the Tsinghua University, in Beijing, found smelly molecules on the skin of mice with dengue made them a lot more susceptible to mosquito bites. The molecule with the most attraction, acetophenone, which increases in people and mice with dengue or Zika, was then applied to the hands of human volunteers. Covering up with clothing and using bed nets and insect repellents are currently the best ways to avoid bites. There are thought to be up to 400 million dengue infections every year. And Zika has been reported in 86 countries around the world. The viruses are most common in South and Central America, Africa, the Caribbean and parts of Asia. Yellow fever, Japanese encephalitis and West Nile disease are also viruses in the Zika family. SOURCE: BBC
