I don't think there is any evidence at the moment, Joe.
What there is evidence of is the incredible contact tracing and use of technology in SE Asia which seems to have kept deaths and infections to manageable levels. This is in today's Sunday Times:
The mobile phones of millions of Vietnamese users of a messaging app named Zalo started buzzing this month with an urgent alert from the ministry of health in Hanoi. Anyone who had visited the Lucky Star gym in the Me Linh district of Hanoi between 6.30am and 8am during a 10-day period in March was instructed to self-isolate immediately and to contact their local authorities.
The recipients of the message knew exactly what it meant: someone who had been using the gym had tested positive for the coronavirus. The government embarked on a nationwide effort to trace that person’s every contact during the period he or she would have been likely to infect others.
If it seems barely credible that a national health service in a country of 97 million people should be able to focus its resources on the gym-going habits of a single citizen, that is exactly what Vietnam has been doing on a near-daily basis for much of the past three months. Television bulletins feature warnings about the potentially infectious activities of individual coronavirus patients. Recent video clips posted on YouTube discussed the travel records of patient No 237 and, soon afterwards, No 243.
In Britain, lockdown measures were introduced in late March after 8,000 cases had been confirmed. It took only eight cases to spur Hanoi into action in late January. Vietnam had suffered through several previous epidemics that crossed its northern border from China. It had learnt to take no chances.
Britain’s coronavirus caseload has since swollen to more than 148,000 confirmed, with more than 20,000 deaths. Vietnam, whose population is 30 million larger than the UK’s, is reporting 270 confirmed cases, without a single death. While sceptics may feel that Vietnam’s status as a one-party communist state undermines the credibility of its figures, independent experts note that its people are among Asia’s most enthusiastic users of western social media.
“I don’t see widespread concerns that the numbers aren’t right,” said Robyn Klingler-Vidra, a senior lecturer in political economy at King’s College London. “I’ve been researching Vietnam for 10 years. I’ve asked colleagues and collaborators there about the virus, and even some who are usually critical of the state say it very much feels as though the cases are low.”
