There's too much social distancing in Vietnam!



I’ve previously written about Vietnam, where my wife was born and grew up – but I’ll say it again, since it’s an amazing story. Despite having a per capita income that’s less than 1/20 that of the US, being much more densely populated than the US, and being next door to China, they have only 35 active Covid-19 cases (with 293 recoveries), and (count ‘em!) zero deaths. This is better than New Zealand, who despite having only 23 active cases has had 22 deaths. As of May 15, there had been no community spread of the virus (i.e. a new case that wasn’t from someone coming from overseas). Vietnam has a population of about 100 million, which is a little less than a third that of the US.

How did Vietnam do this? This article tells the story, along with information my wife has given me (she’s in Vietnam now. She went there to help her parents with health problems, but now she’s very reluctant to return because of a) the danger of spending 17 hours in a metal tube with a bunch of other people who may be infected and not know it, and b) the brutal fact that the US has around 1,000 deaths a day nowadays. In fact, many Vietnamese citizens who live in the US want to return now and the government isn’t letting them in, even if they’re willing to quarantine):

  1. The government has done extensive testing and contact tracing since before their first case in late January (all the East Asian countries learned the importance of doing these things the hard way, especially with SARS). In fact, my wife was tested twice, in February and March, even though she really didn’t have symptoms of the virus.
  2. In March the government put in place mandatory quarantining (i.e. away from their families) for 14 days of anybody arriving from overseas. This is at government expense, although the article makes clear the accommodations aren’t exactly luxurious.
  3. The government also quarantines anybody who has been in contact with a suspected case.
  4. Schools closed as usual for the Tet lunar new year at the end of January, but never reopened until this month. Now they’ll stay open through the summer.

The government locked most of the country down in March. They were planning on opening up in May, but in at least some areas – including, unfortunately, my wife’s province – they haven’t done so. And they just announced that, at least for my wife’s province, they won’t allow reopening of most businesses until late September!

This has created tremendous hardship for people, since there is no safety net of any kind in Vietnam: no Medicare or Medicaid, little private medical insurance, no food stamps or welfare payments, no free government schools, etc. The government said they were giving $40 to every family, but so far it hasn’t shown up, at least where my wife lives.
                                                                                                                
I assume there were some new cases in the province, which is why they can’t reopen now. But I certainly think that, with the level of testing, contact tracing and quarantining that the government is doing, they could figure out a way to open my wife’s province as well. In the US, they would certainly meet the White House criteria for opening up. My guess is that maybe they don’t have enough testing capacity to test a good portion of the province’s citizens, which is really what it would take for them to feel safe about opening. And “safe” in Vietnam obviously has a much stricter meaning than in the US.


I’m once again omitting the table of projections, since the numbers have barely changed in the last few days – in fact, total projected deaths from March-June is within 400 of what it was several days ago. This is because the 7-day rate of increase in total deaths remains solidly at 7%. The numbers below are all current.

I. Total deaths
Total US deaths as of yesterday: 109,159
Increase in deaths since previous day: 1,076 (vs. 1,156 yesterday)
Percent increase in deaths since previous day: 1% (this number was 1% yesterday)
Yesterday’s 7-day rate of increase in total deaths: 7% (This number is used to project deaths in the table above – it was 7% yesterday. There is a 7-day cycle in deaths, caused by lack of reporting over the weekends from closed state offices. So this is the only reliable indicator of a trend in deaths, not the three-day percent increase I used to focus on).

II. Total reported cases
Total US reported cases: 1,902,779
Increase in reported cases since previous day: 21,297
Percent increase in reported cases since yesterday: 1%
Percent increase in reported cases since 7 days previous: 9%

III. Deaths as a percentage of closed cases so far in the US:
Total Recoveries in US as of yesterday: 688,811
Total Deaths as of yesterday: 109,159
Deaths so far as percentage of closed cases (=deaths + recoveries): 14% (vs. 14% yesterday)
Kevin Perry and Royce Howland have pointed out that the recoveries number is inherently flawed, meaning the ratio above doesn’t have much meaning as an absolute number. However, I think it has value as a relative number. For example, the fact that the ratio has fallen from 41% in late March to 14% yesterday, which is much faster than in countries like Italy and France, indicates the US is doing something right – most likely having to do with hospitals being much better equipped to handle Covid-19 patients than they were in March. For further discussion of this issue, see this post.

The tragedy in India

For a great account of what’s going on in India, read this WaPo article. And read this Atlantic article for a good commentary on how India’s wealthier class ignored the lessons of the 1984 Bhopal disaster and let the health care system stagnate, leaving the country unable to handle this sudden surge in the virus. Although it's wrong to say the system stagnated. For the wealthy, it became (and remains) world-class. Does this remind you of another health care system that, at least in the early days of the pandemic, was overwhelmed?  Both articles call attention to the Modi government’s failures, but they both try to spread the blame around. Yes, others are responsible, but the fact that – after a terrible response to the first wave of the virus – the government got lulled into thinking they’d beaten it, so they could open up completely (including holding big political rallies and allowing the annual Kumbh Mela to take place – this year in Haridwar, which I’ve visited and can ...

The Indian variant

The numbers keep improving every week. Both new cases and deaths grew at the same 0.7% rate in the past week, vs. 0.9% for both cases and deaths the previous week. And average daily deaths in the past week were 573. For perspective, the last time deaths were this low was March 31, 2020. But given that daily deaths hadn’t gone above 10 until March 15, the fact that they’d accelerated to 468 on March 31 was a bad sign (at the time, my big concern was that total deaths would end up in the low tens of thousands. In fact, they passed 600,000 last week). This morning, WaPo ran a story on the new Indian variant’s arrival in Britain, where it passed 2,000 cases recently. It seems to be at least 50% more transmissible than what we used to call the UK variant, but which is now the dominant variant in both the US and Britain. And that variant in turn easily displaced what had been the previous dominant variant in both countries, since the beginning of the pandemic (in fact, I remember a lot o...

More than ever, we’re on our own

Leana Wen, a physician and former public health commissioner for Baltimore, wrote another great op-ed piece for the Post today entitled “We’ve reached 200,000 deaths. Our response has gotten even worse than it was at 100,000.” It makes the stark point: By the most important measures of public health, we’re doing worse on a national scale than we were in late May, when the US passed 100,000 Covid deaths. Here are some of her points: “In late May, we had about 20,000 new infections per day. Now we are at double that, with  around 40,000  new daily infections. This is a high baseline to have entering the fall and winter, when the combination of quarantine fatigue and cold weather could drive people to congregate indoors and substantially increase transmission.” “In addition, restrictions keep getting lifted, even in states with surging infections. The nearly 2  million  students returning for in-person instruction will surely lead to more outbreaks, as some colleg...
