A 43-year-old businessman from Ramanattukara in Kozhikode (a coastal district in the southern Indian state of Kerala) has tested positive for Nipah virus, prompting authorities to launch containment and surveillance measures. The patient is on ventilator support in an intensive care unit, and 77 contacts — including 58 healthcare workers and 14 family members — have been identified, with 15 high-risk individuals placed in quarantine. Health officials suspect the man may have been exposed to bat excreta while cleaning a rented warehouse in May, and investigations are underway through a coordinated "One Health" approach involving health, animal husbandry, and forestry departments; this marks the fourth time the deadly zoonotic disease, which has a high mortality rate, has been reported from Kozhikode since the first Indian outbreak there in 2018.
