Has community transmission of coronavirus (Covid-19) outbreak begun in India? It may well have, but we wouldn't know because we are not testing enough people, say experts.
"Community transmission began in India two to three weeks ago, around the same time as other countries. India is not an exception to the way the virus behaves. We just haven't tested a representative sample that the country's population of 1.34 billion demands," said Ramanan Laxminayanan, director and senior fellow at Center for Disease Dynamics, Economics & Policy.
Community transmission occurs when a person with no travel history to a Covid-19-affected country or known contact with a confirmed case tests positive for the disease. It indicates undiagnosed and often asymptomatic people are unknowingly causing infection, which makes it difficult to break the chain of transmission.
