Restrictions put in place to slow the spread of the coronavirus, are hampering efforts to cope with seasonal outbreaks of dengue Cases, an incurable, mosquito-borne disease, doctors have warned.

Also known as “breakbone fever” for its severely painful symptoms, at least 1.1 million cases of dengue and nearly 400 deaths from the disease have been reported in Brazil, where there are over 1.6 million COVID-19 infections.

Southeast Asian countries like Singapore and Indonesia have also dealt with concurrent outbreaks of dengue and coronavirus this year.

Cases are likely to rise soon with the start of seasonal rains in Latin American countries like Cuba, Chile and Costa Rica, as well as the South Asian countries of India and Pakistan.

Dengue typically isn’t fatal, but severe cases may require hospitalization. Prevention efforts targeted at destroying mosquito-breeding sites, like removing trash or old tires and other objects containing standing water, are still the best ways to curb the spread of the disease.

But coronavirus-era lockdowns and other restrictions have meant that these efforts have been reduced or stopped altogether in many countries.

In northwestern Pakistan, plans to disinfect tire shops and markets that had dengue outbreaks in 2019 were shelved due to funds being used for the coronavirus, said Dr. Rizwan Kundi, head of the Young Doctor’s Association.

Health workers who would destroy mosquito-breeding sites in India’s capital of New Delhi are also screening people for the virus.

Having to identify thousands of virus cases has meant that dengue surveillance has suffered in many Latin American countries, added Dr. Maria Franca Tallarico, the head of health for the Americas regional office of the International Federation of Red Cross and Red Crescent Societies.

Experts say that disrupting such prevention efforts is ominous for the global battle against dengue.

The World Health Organization says 2019 was the worst year on record for dengue cases, with every region affected, and some countries were hit for the first time.

Aedes aegypti, the mosquito that spreads dengue, is most prevalent in cities, and experts warn that increased urbanization and warming temperatures due to climate change means that its range will keep increasing.

Oliver Brady, an associate professor at the London School of Hygiene & Tropical Medicine, said Central America and the Caribbean were at higher risk due to overlapping outbreaks.

Working with communities in Latin America to stop mosquitoes from breeding had been the most successful anti-dengue strategy in recent years, Tallarico said. But with strict limitations on movement, she said they didn’t know whether these measures were still happening, and “this is the big concern for us.”

A shortage of protective equipment also means limiting the number of first responders who can check on people with fever or cough, she said.

“My concern is that you have (many) more cases of dengue … but the capacity of the system to notify (and) test is limited,” she said.

Dengue patients need acute care, and this could lead to a “double whammy” that overwhelms health care systems, said Scott O’Neill, founder and director of the World Mosquito Program.
