<p>As the second wave of the Covid-19 epidemic in India swells up, scientists have warned that the second surge would worsen in the coming weeks as seen from the computer models that are being used to track the outbreak.</p>.<p>The alert is based on the rising value of R (reproduction number) – a parameter to denote the virus's ability to spread the infections – in almost all the big states.
