The 8% prevalence can be extrapolated to the 1 million registered working population of Karachi, meaning at least 80,000 infected cases in Karachi alone, with 70,000 being currently infected, unaware and spreading infection to those around them. @Getzpharmapubli https://twitter.com/hyzaidi/status/1264499888781492225

If the assumptions hold true for the rest of Pakistan, of its 61.7 million registered workers, at least 4.9 million could already be exposed and infected.

Of the 261,065 registered medical and dental practitioners in Pakistan who are on the frontline fighting Covid-19, at least 11% or 28,000 may currently be exposed to and infected with Covid-19, with no or only mild symptoms.

For the 41,151 officially confirmed cases of Covid-19 in Pakistan (as of May 17) and taking a family size of seven, at least 53,400 people are already infected with Covid-19, unaware of it and spreading it around.
