Restrictions on Community Mobility Impact on Decreasing DHF Cases – A recent study published in the Lancet journal said that the impact of restrictions on community mobility did not only affect the decline in COVID-19 cases.

The study, published in the Lancet Infectious Diseases, found nearly 750,000 fewer dengue cases than globally predicted for 2020, when the coronavirus began to spread.

The results of the study were surprising, said senior author Oliver Brady, because they showed a significant reduction in dengue cases when people could not freely go outside their homes to visit other places such as schools.

DHF cannot be transmitted between humans, but only through the bite of the Aedes mosquito during the day.

However, scientists previously thought that most transmissions occurred in homes and neighborhoods, rather than elsewhere.

“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 professor Brady of the London School of Hygiene and Tropical Medicine.

New approaches to controlling dengue disease, including spraying insecticides in classrooms and contact tracing to find out where infected people have recently visited, can now be tested, Brady said.

Dengue is a viral infection that can cause fever and flu-like symptoms, although in severe cases it may cause internal bleeding and be life-threatening.

The research examined data from 23 countries in Latin America and Southeast Asia where dengue is endemic.

The World Health Organization (WHO) says the global incidence of dengue is growing dramatically and it is estimated that about half of the world’s population is at risk of dengue infection.
