West Nile virus spreads most efficiently in the United States at temperatures between 24 and 25 degrees Celsius (75.2 to 77 degrees Fahrenheit). eLife is showing.

Result is, May lead to expansion of West Nile expansion In some places, it can cause reductions in others, and it provides insight into where and when these changes can occur.

“It’s important to understand how temperature changes affect the transmission of mosquito-borne diseases as the climate warms,” ​​said a postdoctoral fellow at Stanford University, California, when the study was conducted. The author, Marta Shocket, said. It has been implemented and is currently a postdoctoral fellow at the University of California, Los Angeles.

To do this, Shocket and her colleagues have developed a model that assesses the effects of temperature on six mosquito-borne viruses. Four of them occur in the United States. These viruses (West Nile virus, St. Louis encephalitis virus, Eastern and Western horse encephalitis virus, Sindbis virus, Rift Valley fever virus) were grouped in this study because they share the same type of mosquito carrier. ..

The model used laboratory experiments that measured how different temperatures affect mosquito survival, bite rate, reproduction, development, and ability to infect viruses. The team used data on human viral infections in the United States to validate the West Nile model. They found that West Nile virus is most easily transmitted at moderate temperatures, but extreme temperatures limit the place where mosquito carriers live and transmit the virus.

“Most of the viruses featured in this study are temperate viruses rather than those commonly studied. “Comparing these results with those of tropical diseases such as malaria and dengue, we found that the optimal temperature and low temperature limits for the spread of the virus were lower. As expected, more compared to tropical diseases. “

The results are mosquito-borne as the temperature rises, especially as the majority of the population (70%) now live below optimal temperatures and are likely to see an increase in infections associated with climate change. It suggests that sexual illness can make a big sacrifice in the United States. This is compared to 30% of the population living in areas where summer temperatures exceed optimal temperatures. That is, infections may decrease with climate change. Rising temperatures can also extend the virus transmission period from early spring to autumn.

“Climate variability can increase transmission of West Nile and other mosquito-borne viruses in most of the United States,” concludes Erin Mordekai, an assistant professor of biology at Stanford University. .. “But these diseases also depend on human contact with mosquitoes that come into contact with wildlife, so factors such as human land use, mosquito control, mosquito and virus adaptation, and the emergence of new viruses. Predicts the future of mosquito-borne. challenging. ”


Warming climate may cause more West Nile outbreaks in Southern California
