Hong Kong authorities say nearly half a million people have registered for a free universal coronavirus testing program that is due to begin from Tuesday, AP reported.

Residents registering online have already booked out 80 testing sites located in gymnasiums and community centers for the initial day of the program, according to the government’s website.

Hong Kong launched the program in an effort to track down paths of infection that have consistently added to case numbers despite strict social distancing and other measures.

Hong Kong has reported another 15 cases of coronavirus and one additional Covid-19 fatality, bringing its totals to 4,801 cases and 88 deaths.
