New cases of Zika virus infection have been detected in Dhaka this time as eight patients were infected with the virus over the past three months.

According to the Institute of Epidemiology, Disease Control, and Research (IEDCR), the affected individuals are residents of Dhanmondi, Shyamoli, and Banani, with infected Aedes mosquitoes also detected in their homes.

IEDCR Director Professor Tahmina Shirin confirmed that the cases were detected through sample testing conducted over the last two months. This resurgence follows the first identification of Zika in Bangladesh in 2014. 

The International Centre for Diarrhoeal Disease Research, Bangladesh (ICDDR,B) also reported five Zika cases last year, suggesting that the virus continues to circulate in the region.

The Zika virus, transmitted primarily through the bites of Aedes mosquitoes, often presents mild symptoms such as rash, fever, red eyes, and joint pain, which typically resolve within a week. However, up to 80% of infected individuals may remain asymptomatic, complicating surveillance and containment efforts.

The IEDCR recommends symptomatic treatment, including hydration and rest, and advises hospitalization if symptoms worsen.

While cases have been reported in Dhaka, no data are currently available on the virus's spread outside the capital due to limited testing.

Public health experts stress the need for expanded surveillance, mosquito control initiatives, and community awareness campaigns.

Zika, first discovered in Uganda in 1947, has caused significant outbreaks globally, including in the Americas and Asia. Since its 2016 designation as a Public Health Emergency of International Concern by the World Health Organization (WHO), efforts have focused on research, vaccine development, and vector control. Despite declining global cases, localized outbreaks persist, particularly in regions with favorable mosquito breeding conditions.
