VIENTIANE, May 5 (Vientiane Times/ANN): The Laos government has extended the lockdown for another 15 days until May 20 in an ongoing effort to contain the Covid-19 outbreak as new cases continue to surge. The National Taskforce for Covid-19 Prevention and Control announced to continue imposing the measures in a press conference on Tuesday. The government has imposed a lockdown in the capital of Vientiane since April 22 after suspected super-spreaders had caused a widespread outbreak.
