DHAKA: Bangladesh’s dengue fever outbreak this year is its second deadliest on record, raising concerns over widespread transmission as infection rates show no signs of slowing. Each year, dengue fever becomes a major health concern in Bangladesh during the monsoon season between July and October, with thousands of people contracting the potentially deadly virus transmitted by the Aedes mosquito. The incidence of the disease has increased dramatically since the early 2000s, with the worst outbreak claiming 1,705 lives last year.
