Dhaka, February 7, 2026 : Scientists in Bangladesh have reported the detection of a novel bat-borne virus in human patients, identified as Pteropine Orthoreovirus (PRV). The discovery has drawn immediate attention from the global health community, given its parallels to the Nipah virus, which has caused periodic outbreaks in the region. While research is ongoing, experts stress the importance of vigilance, surveillance, and public awareness to mitigate potential risks.
Timeline of PRV Emergence
- Late January 2026
Researchers identify unusual viral symptoms in patients and confirm the presence of PRV. - Early February 2026
Investigations trace the likely source of transmission to fruit bats (flying foxes). Preliminary evidence suggests contamination of raw date palm sap, a traditional beverage, as a possible route of spillover. - February 2026 (Week 1)
Health experts highlight similarities with Nipah virus transmission pathways, prompting calls for immediate public awareness campaigns on safe food practices. - February 2026 (Week 2)
Public health authorities begin strengthening surveillance systems, laboratory testing, and case management protocols. International researchers signal readiness to collaborate with Bangladeshi teams to accelerate understanding of PRV. - Ongoing (2026)
Studies continue to assess PRV’s pathogenicity, clinical impact, and potential for human-to-human transmission. Preventive measures, including boiling sap and protecting collection pots from bats, are promoted to reduce spillover risks.
Understanding the Threat
While PRV belongs to a different viral family than Nipah, both share a bat reservoir and potentially similar transmission routes. Scientists caution that the full spectrum of illness caused by PRV is still under evaluation. Early findings suggest symptomatic cases, but its epidemic potential remains uncertain.
Public Health Response
Authorities are prioritizing:
- Enhanced disease surveillance and laboratory capacity.
- Public education campaigns on safe food handling, especially regarding raw date palm sap.
- International collaboration to develop diagnostic tools and explore therapeutic options.
Key Points
- PRV has been detected in human patients in Bangladesh.
- Transmission is suspected via bat-contaminated raw date palm sap.
- Similarities with Nipah virus raise concern, though PRV is a different viral family.
- Surveillance, awareness, and preventive measures are being scaled up.
- Global scientific cooperation is underway to study the virus.
