“The issue is the severity of dengue has kind of gone out of the general public and media’s radar because the nation goes by way of a political turmoil forward of the following election,” he stated.

One more reason behind the excessive fatalities is the outbreak in rural areas, he stated.

“This 12 months, the illness has unfold throughout the nation, and in rural areas, the well being amenities are very scarce. Moreover, most individuals aren’t conscious of the severity of the sickness. If you happen to don’t get therapy on time, it might probably get deadly. And that has occurred in lots of areas.”

What induced the file deaths

In the meantime, entomologists say they could have discovered the doable cause behind this 12 months’s file outbreak.

Kabirul Bashar, professor of medical entomology at Bangladesh’s Jahangirnagar College, instructed Al Jazeera that the sample of dengue subsiding by September modified final 12 months when the illness reached its peak in October and induced 86 deaths. A 12 months earlier than that in 2021, that quantity was 22.

“We rang an alarm final 12 months, saying the very sample of the illness has modified. Now dengue is just not a illness related to monsoon anymore, it’s a year-long factor,” stated Bashar, who can also be the lone scientific knowledgeable on the nation’s Nationwide Anti-Dengue Committee.

The scientist stated local weather change is altering patterns in temperature, rainfall and different pure phenomenon.

“Now, we see nearly monsoon-like constant rain all through October and early November. It adjustments the breeding and lifecycle of the Aedes mosquito populations,” he stated, referring to the kind of mosquito that carries dengue.


Dengue is usually prevalent in South and Southeast Asia between June and September, when stagnant water offers the best habitat for the Aedes mosquito, which normally breeds in clear water and feeds throughout the day.

However in a groundbreaking discovering, Bashar, who has been finding out mosquitoes for greater than 20 years, found that the mosquitos now breed even in soiled sewers and in saline seawater.

“So, on the one hand, you might have unusually constant rains throughout the low season that present an excellent floor for his or her breeding and, alternatively, you might have the mosquitoes broadening their horizon for copy. It’s a double whammy,” he instructed Al Jazeera.

Entomologists additionally found that the 2 most generally used pesticides, malathion and temephos, had change into “ineffective” in opposition to Aedes mosquitoes in Bangladesh.

“These two pesticides have turned sub-insecticide, shedding their efficacy in opposition to mosquitoes as a result of they’ve developed resistance,” stated Md Golam Sharower, professor on the Nationwide Institute of Preventive and Social Drugs.

“Sadly, most of our metropolis companies throughout the nation nonetheless use these two pesticides, which assist little or no in controlling the mosquito inhabitants.”

Bashar stated the federal government must take a full-fledged five-year plan to manage the unfold of dengue and finally eradicate the Aedes mosquito inhabitants.

“The illness will solely worsen within the upcoming years if such a plan is just not activated instantly,” he stated.

Again at Dhaka’s Mugda Hospital, Mayna, overwhelmed by the unusually lengthy dengue epidemic, has begun to rue her choice to work as a cleaner.

“I assumed dengue would subside with the tip of the wet season, however sufferers maintain coming in every single day. Overlook the ward beds, there is no such thing as a house even within the hospital corridors,” she instructed Al Jazeera.
