The recent case of five people testing positive in Kerala three weeks after returning from Dubai has raised questions on whether 14 days self-isolation period is enough. This further raises the question on whether the incubation period too could go beyond 14 days. Doctors have now clarified that while 14 is enough, 28 days may be better, they clarify on this and a host of other issues like whether predisposed patients need special masks and whether 30 days after travel you are safe to see your family.
