To combat again, CNEA biologists have been experimenting with atomic sterilization since 2016. They’re sterilizing 10,000 males per week and intention to extend that to 500,000. They count on to launch the primary batch of sterilized males in November.

“They’re sterilized by way of ionizing power and people sterile males are freed into the fields and once they meet with a wild feminine, their offspring aren’t viable,” stated Garcia Alba. “This fashion, by successive launch of such males we’ll be capable of cut back the inhabitants of the vector mosquito.”

Dengue is transmitted by way of the bites of aedes aegypti mosquitoes. Its signs embrace fever, eye, head, muscle and joint ache, nausea, vomiting and fatigue.

Comparable methods to sterilize pests utilizing the identical radiation present in X-rays have been utilised for many years, serving to international efforts to manage ailments comparable to chikungunya, dengue and Zika.
