Vietnam’s Covid-19 tally now stands at 1,304 cases with 1,142 recoveries, of these 18 announced Thursday, and 35 deaths. Many of the fatalities were elderly patients with underlying conditions like diabetes and kidney failure.

Of the active cases, 23 have tested negative at least once. Over 16,000 are in quarantine nationwide, and no community transmission has been recorded in over two months.
