  In India the COVID-19 infected population has not yet been accurately
established. As always in the early stages of any epidemic, the need to test
serious cases first has meant that the population with asymptomatic or mild
sub-clinical symptoms has not yet been analyzed. Using counts of fatalities,
and previously estimated parameters for the progress of the disease, we give
statistical estimates of the infected population. The doubling time is a
crucial unknown input parameter which affects these estimates, and may differ
strongly from one geographical location to another. We suggest a method for
estimating epidemiological parameters for COVID-19 in different locations
within a few days, so adding to the information required for gauging the
success of public health interventions
