Nipah virus: Ahead of the bat breeding season, Kerala’s Health Department has initiated awareness activities in five districts in the State that are considered to be hotspots for the zoonotic infection – Kozhikode, Malappuram, Kannur, Wayanad, and Ernakulam.
According to a Mathrubhoomi report, The Kozhikode-based Kerala One Health Centre for Nipah Research has recently issued fresh warnings, urging heightened vigilance in Malappuram, Kozhikode, Kannur, Wayanad and Ernakulam districts. These districts have previously recorded the presence of the Nipah virus in humans or fruit bats.
Every year, the months from May to September, which coincide with the breeding season of fruit bats, are regarded as the peak period for the virus’s spread. However, recent studies suggested that the risk extends into February as well, leading to increased monitoring efforts.
Meanwhile, Malappuram District Medical Officer Dr R Renuka stated that any patient presenting with a viral illness affecting the brain is being tested for Nipah. Reportedly, this protocol applies to patient visiting both government and private hospitals. According to the Mathrubhoomi report, the authorities have emphasised that if there are any suspected case, samples will be collected and sent to Manjeri Medical College or Kozhikode Medical College for initial testing.
