In a follow-up on the Nipah virus case and death in Kerala state, India earlier this month, the World Health Organization published a Disease Outbreak News Friday that provides some additional information:
On 4 September 2021, the Kerala State Health department reported an isolated case of Nipah virus disease in Kozhikode district, Kerala state, India. Nipah has a relatively high case fatality ratio, and is an emerging zoonotic disease of public health importance in the South East Asia and Western Pacific WHO Regions.
This is the fifth outbreak of the disease in India (Siliguri town in 2001, followed by a second outbreak in Nadia district in 2007, both in West Bengal state. In 2018, an outbreak was reported in Kozhikode district, and in 2019, another outbreak in Kochi district, both in Kerala state).
On 29 August, a 12 year-old boy developed low grade fever, and the family sought care at a local health care facility. On 31 August, he was transferred to several hospitals as his condition deteriorated. On 1 September, the patient’s condition continued to deteriorate, and the family requested his transfer to another hospital in Kozhikode.
On 3 September, plasma, serum and cerebrospinal fluid samples were sent to the National Institute of Virology in Pune, India. On 4 September, the presence of Nipah virus in the plasma, cerebrospinal fluid and serum samples was confirmed by real-time polymerase chain reaction (RT-PCR) and IgM antibodies was confirmed in the plasma sample by ELISA serology test. On 5 September, the patient died and a safe burial and cremation were performed the same day in Kozhikode.
As of 6 September, epidemiological investigations identified contacts, including health care workers and close family members, who were placed under quarantine.
The current isolated case was reported in a rural area in Kerala state where an outbreak was previously reported in 2018. India has experienced and contained Nipah virus disease outbreaks in the past and has demonstrated the capacity to carry out outbreak control activities, including case identification, laboratory testing, case management, contact tracing and risk communication. This event is an isolated case and the risk is low at national level and low at the regional level.
