Initially, researchers suspected that more people were exposed to dengue at home.
REPUBLIKA.CO.ID, NAIROBI — The restrictions on mobility and community interaction implemented to prevent the spread of Covid-19 may be related to the sharp decline in dengue cases in 2020. Experts say this trend provides a new perspective on how dengue hemorrhagic fever can be controlled.
Research in journals Lancet Infectious Diseases found nearly 750,000 fewer dengue cases than globally predicted for 2020, when SARS-CoV-2 began to spread. Senior author Oliver Brady said the research results were surprising.
“Because it shows a significant decrease in dengue cases when people cannot freely go outside their homes to visit other places, such as schools,” said Brady, quoted Thursday (3/3/2022).
DHF cannot be transmitted between humans. People contract dengue hemorrhagic fever through mosquito bites Aedes aegypti at noon. Scientists previously thought that most of the transmission occurred in the home and surroundings than in other places.
“This is a strange trend that we didn’t expect, a surprising result, which opens the way for thinking about conducting more detailed intervention trials,” said Brady, professor from the London School of Hygiene and Tropical Medicine.
