Decline in dengue by introducing bacteria Wolbachia

According to a research carried out by Monash University Australia, a city was subjected to the protection by dengue virus. This was brought about introducing bacteria Wolbachia in 2014, by releasing the engineered mosquitoes into communities over a period of four monsoon seasons, in turn resulting in a decrease in dengue virus. This aids in preventing the transmission of mosquito-borne diseases such as zika and malaria.

The bacteria is mainly found is 60% of insect species. These bacteria were introduced into female mosquitoes and this spread through the species increasing the content in mosquitoes with the bacteria. The advantage of this bacteria is the hindering capability of dengue virus from growing within the mosquito and in turn halts transmission.
