Bangladesh is witnessing the highest death rate from dengue since 2003 Disease outbreak forecast to continue for the next two months DHAKA: Bangladeshi doctors are on alert as this year’s mortality rate from dengue fever is the highest in over two decades. Each year, dengue fever becomes a major health concern during the monsoon season between July and October, with thousands of Bangladeshis contracting the viral and potentially deadly disease transmitted by the Aedes mosquitoes breeding in freshwater pools. The disease used to be rare in the 1960s, but since the early 2000s, its incidence has increased dramatically. While the worst outbreak was recorded last year, with over 211,000 people hospitalized across the country, this year the country is witnessing the highest death rate from the disease since 2003. Out of 34,121 dengue patients admitted to hospitals, 177 have died, according to Directorate General of Health Services data. “This year, the fatality rate from dengue is higher than in the previous years, although the number of patients is less,” Dr. Mohammed Mushtuq Husain, adviser at the Institute of Epidemiology Disease Control and Research in Dhaka, told Arab News. “The fatality is worrying as it is the highest in the world at the moment.” The death rate has reached 0.52 percent, surpassing last year’s 0.49 percent. “This dengue trend is feared to continue. When this monsoon rain spell is over, it will continue for the next two months — it’s the life cycle of the dengue virus and Aedes mosquitoes,” Husain said. Dr. Muzaherul Huq, former World Health Organization regional adviser, warned that prevention and early detection need to be strengthened as the outbreak is not over yet. “The way dengue case fatality is increasing, it may take a worrying (turn) at any moment. So, we need to strengthen the prevention methods against the dengue virus. Otherwise, we won’t be able to fight this,” he said. Deaths are mostly occurring as patients come to hospitals at the last stage, often after a long time traveling as most specialist and testing facilities are available only at major clinics. Many also come infected with dengue for the second or third time. A person can be infected several times with different variants of the virus. “There are four strains of dengue virus. If someone gets infected with dengue in previous years, second or third-time infection causes more risks for him or her,” said Brig. Gen. Mohammed Rezaur Rahman, director of Bangabandhu Sheikh Mujib Medical University in Dhaka. “Dengue is a viral disease, and it mutates regularly. This is why it’s tough to eradicate.” There is no treatment for the disease yet, and the focus is on treating its symptoms. In its severe form, it causes internal bleeding and deadly organ impairment.
