What This Article Covers

1.A Nature report analyzing recurrent Nipah spillovers in India finds Kerala and West Bengal exhibit different outbreak patterns due to ecological factors and health system strength.

2.Kerala experiences frequent spillovers but limits them to small clusters via strong surveillance and a One Health approach, while West Bengal has fewer spillovers but historically larger healthcare-related transmissions.

3.The 2026 West Bengal outbreak (Barasat, 2 healthcare workers infected) was detected early through proactive AES/ARI surveillance via 10 VRDLs, a significant improvement from the 2001 Siliguri outbreak (66 cases, 68.2% CFR).

The Big Picture
Prelims · HighMains · High

A Nature report reveals Nipah virus outbreaks in India follow two distinct patterns shaped by ecology and health systems. Kerala sees frequent spillovers but contains them via strong surveillance, while West Bengal experiences fewer but larger healthcare-associated outbreaks. This highlights the critical role of One Health preparedness and ecological factors in zoonotic disease management.
