Nipah Virus Antibodies in Bats, the Philippines, 2013-2022
Emerging Infectious Diseases
|July 24, 2025
Abstract:
In 2014, an outbreak of zoonotic Nipah virus (NiV) occurred on Mindanao Island, the Philippines. We investigated the prevalence of NiV in Philippine bats. Because neutralizing antibodies were detected in insectivorous bats on Siargao Island, public health officials should consider that the distribution range of NiV is not limited to Mindanao Island.
Insights
Nipah virus (NiV) can spread to insectivorous bats, as shown by antibody detection on Siargao Island. This finding suggests NiV
Area of Science:
- Veterinary Medicine
- Infectious Diseases
- Epidemiology
Background:
- An outbreak of zoonotic Nipah virus (NiV) occurred in the Philippines in 2014.
- Bats are known reservoirs for Nipah virus.
Purpose of the Study:
- To investigate the prevalence of Nipah virus in Philippine bats.
- To determine the geographic distribution of Nipah virus in the Philippines.
Main Methods:
- Serological investigation of bats for Nipah virus antibodies.
- Sampling of insectivorous bats on Siargao Island.
Main Results:
- Neutralizing antibodies against Nipah virus were detected in insectivorous bats on Siargao Island.
- This indicates Nipah virus is present in bat populations beyond Mindanao Island.
Conclusions:
- The distribution range of Nipah virus is not limited to Mindanao Island.
- Public health officials must consider a wider geographic area for Nipah virus surveillance and control efforts.
