WHEN AEDES AEGYPTI MOSQUITOES CARRY NATURAL BACTERIA CALLED WOLBACHIA, THEY REDUCE THE MOSQUITOES’ ABILITY TO TRANSMIT VIRUSES LIKE DENGUE, ZIKA, CHIKUNGUNYA AND YELLOW FEVER. FIND OUT HOW.
Mosquitoes pick up viruses by biting infected people. When they bite again, they can transmit the virus to the next person. This is how mosquito-borne diseases spread.
Mosquitoes do not naturally carry viruses – they can only get them from infected people.
Since only female mosquitoes bite humans, only female mosquitoes can transmit viruses.
The Aedes aegypti mosquito is the main transmitter of dengue, Zika, chikungunya and yellow fever viruses.
Aedes aegypti mosquitoes originated in Africa, but they have spread through tropical and subtropical regions around the world.
For Kasun Chameera, who lives in Sri Lanka’s densely populated capital Colombo, dengue fever is a disease which has afflicted many loved ones, including his brother.
“We fear death when we hear about dengue,” Chameera said. “It’s present almost everywhere in my district, and spreads faster in the city than in the villages.”
His brother “suffered a lot from it,” Chameera said. “For at least one to two months, he would be tired walking just 10 steps. We were very scared.”
Also known as breakbone fever because of the severe pain it can cause, the disease is a growing threat across Asia, where 70% of the world’s dengue cases occur. The virus is transmitted to humans through the bites of the female aedes aegypti and aedes albopictus mosquitoes, which thrive in both tropical and subtropical urban areas.
Worldwide, it is estimated to infect about 390 million people every year, with more than half of the global population now at risk.
Recent weeks have seen soaring cases in Singapore, Malaysia and Vietnam, despite the peak season usually lasting from June to October. Reported cases in Singapore topped the 10,000 mark in the first five months of this year, already exceeding the 5,258 cases reported in all of 2021.
In Japan, 461 cases were reported in 2019 — mainly found in travelers from Asian countries. But with the borders effectively closed during the pandemic, the number of cases dropped to 43 and eight in 2020 and 2021, respectively.
Moscow Admits to Problems in Military Mobilization as Russians Protest, Flee Draft
Kremlin spokesperson Dmitry Peskov has admitted to errors (NYT) in Russia’s ongoing military draft as protests against it erupt nationwide and men flee the country by the tens of thousands. While Moscow originally said only men with military experience would be required to fight in Ukraine, draft officers have attempted to conscript (FT) a broader group. Peskov blamed local officials for the problems. Ethnic minorities appear to be disproportionately targeted (Moscow Times) in the draft. Yesterday, a man shot and wounded a recruitment officer at a draft office in Siberia. Since last Wednesday, an estimated 261,000 men have fled the country, independent Russian newspaper Novaya Gazeta reported, citing official sources.
