More research needed on dengue

Dengue has emerged as a pressing public health concern in Bangladesh, with its growing severity calling for urgent and coordinated action. The virus exists in four serotypes-DENV-1, DENV-2, DENV-3, and DENV-4. Infection with one serotype provides immunity against that specific type, but individuals remain vulnerable to other serotypes. Alarmingly, secondary infections can become more dangerous due to a phenomenon known as antibody-dependent enhancement (ADE), which compromises the immune system and increases the risk of severe complications such as dengue hemorrhagic fever.

Research has shown that certain serotypes, particularly DENV-2 and DENV-3, tend to cause more severe illness. Moreover, the dengue virus mutates rapidly, adapting to new environments, which not only increases its infectivity but also reduces the effectiveness of existing vaccines and treatments. This makes genetic surveillance-in addition to entomological monitoring-crucial for tracking serotype shifts and emerging strains.

To combat the threat of dengue, Bangladesh must adopt a comprehensive approach. Government initiatives, scientific research, community awareness, and personal preventive measures must work hand in hand. Urban planning must be improved, waste management strictly enforced, and public awareness campaigns intensified to educate people about mosquito breeding prevention and personal protection.

If proactive and sustainable measures are not implemented now, the consequences could be far more devastating in the coming years. Aedes mosquito control through collective community action and enhanced public education is essential. The time to act is now before this public health threat further worsens and claims more lives.
