Nipah virus outbreak: 100 people quarantined in West Bengal

As long as it is very deadly I think there is a reduced risk of global pandemic, the hosts are easily isolated and the risk mitigated. I think the problem is if this virus stays dormant for a prolonged period or if the symptoms pass for something else during the early stages. Covid-19 had both of those, 72 hours of no symptoms and then 2-3 days of what looks like a regular cold or mild flu.
