Bangladesh: Dengue spike amidst worsening coronavirus crisis

A sharp spike in dengue cases is straining Bangladesh’s fragile healthcare system, which is already battered by a worsening coronavirus crisis in the country. Just this month, 1,920 people were diagnosed with the mosquito-borne disease till Friday, marking a more than 600 percent jump in cases from June when 272 cases were reported.

According to the Directorate General of Health Service (DGHS), a total of 2,292 patients have been diagnosed with dengue this year, including at least three deaths.

Almost all the dengue cases, barring about 70, have been found in Dhaka, Bangladesh’s sprawling capital, home to about 17 million people.

The dengue outbreak has put further pressure on Bangladesh’s healthcare, which is already on the brink of a collapse due to a vicious third wave of the coronavirus.

On Thursday evening, 239 Covid-19 related deaths were reported across the country in the past 24 hours, raising the death toll to 20,255.

During the same period, 15,271 new coronavirus cases were reported, taking the total caseload to 1,226,253, according to the health ministry.

Bangladesh witnessed its worst-ever dengue outbreak in 2019 when it recorded more than 100,000 cases and 179 deaths.

There was a lull last year when 1,405 patients were diagnosed across the country, with seven killed according to the DGHS data.

This year, however, the situation is complicated by the fact that Covid-19 and dengue present similar symptoms, making their illnesses more difficult to diagnose.

And most hospital beds and Intensive Care Units (ICUs) have been taken up by coronavirus patients, making it difficult for patients with a severe case of dengue to get admitted to a facility.

The World Health Organisation says dengue is caused by a virus with four distinct strands. Recovery from infection by one provides lifelong immunity against that particular strand but subsequent infection by other strands increases the risk of developing severe dengue.

In Bangladesh, a large number of dengue patients this year are being infected with DEN-3, a variant of the dengue virus that can increase mortality risk, according to Dr. Tahmina Shirin, director of the country’s Institute of Epidemiology, Disease Control and Research (IEDCR).

In previous years, Bangladesh witnessed outbreaks of DEN-1 and DEN-2 strands but this year DEN-3 is more prevalent, said Shirin, adding that DEN-3 and DEN-4 strands are considered deadly and cause plasma leakage, respiratory distress and organ impairment in patients.

Dr. Md Robed Amin, director of the DGHS Non-Communicable Disease Control (NCDC) unit, told Al Jazeera that this year, the dengue cases are high because of what he called a “wave pattern.”

“Dengue cases increase every alternate year. We saw massive dengue cases in 2019, so increasing dengue cases were probable in 2021,” he said.

Amin said entomologists earlier this year had warned of the growth in dengue cases in the country.

According to entomologist Kabirul Bashar’s projection, the dengue situation in Bangladesh will worsen in August but he appreciated the efforts taken by the Dhaka administration in checking the spike.

“I have seen the two city corporations of Dhaka get active in controlling mosquito’s population. If their activities go on in full swing, then the dengue cases might decrease,” he said.

Brigadier General Jobaidur Rahman, the chief health officer of Dhaka North City Corporation, told Al Jazeera they have already started a special cleanliness drive across the capital.

Meanwhile, the Bangladesh government has extended the ongoing closure of all secondary and higher secondary educational institutions till August 31 as a preventive measure against the further spread of coronavirus.

The decision is also applicable for Ebtedayee and Qawmi madrasas across the country, according to a press release of the education ministry.

Based on recommendations by the National Technical Advisory Committee on Covid-19, the government has extended the closure considering the safety of students, teachers, employees and guardians amid growing Covid-19 infections and the countrywide lockdown.
