Zika Virus Australia: Treatment Found in AU? Warmer Climate Decreases Risks

Health researchers have linked climate change with Zika virus transmission. They said that as the climate will turn warmer, there will be a decline in the transmission of the infection.

The discovery has come as a counter to previous projections that claimed the increase in Zika virus infection as it will be easier for the infection to get transmitted easily in a warmer climate. According to reports, people hardly take mosquito-borne diseases seriously until they knock on one’s door.

Zika virus transmission grabbed serious attention only when newborn babies started getting affected by their mother’s Zika infection. Other diseases caused by mosquito stings, including chikungunya, have also become quite common these days.

Every year, there are hundreds of counts of dengue cases. Out of these,  there are many children who are diagnosed with severe illness. After the intense effect of the diseases, researchers have started finding ways of treating the mosquito-borne diseases, including Zika.

The research has been conducted to figure out the global health problem and its treatment through natural climatic change. The Australian National University’s co-lead researcher Associate Professor David Harley said that the risk of dengue might be in wet tropics of Australia’s northeastern region. The scenario might be evident in 2050 under high-emission instances. This will occur as a result of the drying of the sites where mosquitoes breed.

The warmer climate is predicted to make the sites unfavorable for the survival of these mosquito species, thereby leading to the decline in their population. “While climate change generally poses a major threat to humanity, it also may reduce the incidence of dengue in some areas,” Harley said as quoted by the Eurek Alert.

The researcher also specified that the mosquitoes that transmit dengue are also the ones that spread Zika virus. “There is significant concern in countries on the margin of the tropical areas where dengue is mainly found, that with global warming, dengue and other mosquito-borne viruses such as Zika will encroach and become common,” Harley said.

“Previous projections have suggested that climate change will increase transmission of mosquito-borne diseases globally. Our work, using a mathematical model based on Queensland conditions, suggests that dengue transmission might decrease with greater warming.”
