As governments around the world begin easing their lockdowns — and as new infections are inevitable — they will get another chance to get their responses right.
Without a vaccine in sight, what governments need to do to safely lift lockdowns is test, trace and quarantine, according to WHO spokeswoman Dr. Margaret Harris.
“We need to know where the virus is, and then separate the sick from the healthy — that’s why you need testing. You need to check that people who have symptoms actually have the virus, and then find people who they’ve been in contact with and isolate them,” she told CNN.
“If you can’t do that, then you go back to square one.”
US misses testing benchmark (but so does the UK)
The way some leaders talk about the level of testing can be confusing. President Trump had claimed that the US had carried out the most tests in the world, and while that may be true, per capita, it’s not leading.
While it’s useful to look at how widely a country is testing per capita, the WHO says there is a better benchmark to measure whether a country is testing adequately. Dr. Mike Ryan, Executive Director of the WHO’s Health Emergencies Programs, said recently that a good benchmark is to have at least 10 negative cases for every one positive case confirmed. That means if a state or country carries out testing and comes back with positive cases of around 9% or under, then it’s likely that it is testing well.
The US has a positive result rate of 18.8%, going by the COVID Tracking Project’s figures cited by JHU.
Such high rates suggest a country is only testing the worst cases, usually people who are severely ill and in hospital, Harris said.
It’s the same picture in individual US states. Georgia has carried out around 101,000 tests, with a positive result rate of 21.6%, even further away from the WHO benchmark.
Elsewhere, several European countries are also lagging far behind in testing and will need to catch up to safely reopen their societies.
The UK stands out, with just over 610,000 tests carried out and a positive case rate of 23.4%, worse than Georgia.
The difference is, the UK government has extended its social restrictions. But it is looking at when and how to lift its lockdown.
France and Sweden are also performing tests below the WHO benchmark.
Germany lifts lockdown with caution
Germany makes a good case for comparison with the US. It too has begun easing its lockdown, and it too leaves much of the decision-making to individual states. Yet its approach is far more rigorous than what we’re seeing in Georgia, and Germany’s states are showing a uniform sense of caution.
By the end of last week, RKI reported that Germany had tested more than 2 million people and has a positive result rate of 7.5%, well above the WHO benchmark.
Last week, German Chancellor Angela Merkel laid out a list of steps the country would undertake to begin lifting its lockdown, and on Monday stores up to 800 square meters in size began reopening, as long as they have hygiene and social distancing measures in place.
Bookshops, car dealerships and bike stores can also now reopen regardless of their size. Restaurants, bars and gyms will remain closed.
Merkel also announced that the country would ramp up its contact tracing efforts, deploying a team of five officers for every 20,000 people in the population to trace people who may have come into recent contact with every confirmed case.
But Merkel has repeatedly warned that the situation could quickly reverse if people do not adhere to social distancing measures, which are still in place.
On Thursday, the Chancellor warned Germany was on “the thinnest ice” after many people flocked to shopping areas and pedestrian zones this week, prompting German virologists to warn against complacency. While Merkel supports the reopening decisions made by the federal government and the states, “their implementation worries me … they appear to be very bold, maybe too bold,” she said.
Germany only considered reopening as its reproduction rate — the average number of people each person is infecting — had fallen below 1, to 0.7. According to the WHO, keeping this rate below 1 means the virus can decline and eventually die out. On Friday, however, German authorities reported that rate had gone up to 0.9.
Trump contradicts White House stance
The messaging in the US has been less coordinated and clear.
Trump has also supported protesters rallying against stay-at-home measures that they say violate their rights.
“Our next measured step is driven by data and guided by state public health officials. We will continue with this approach to protect the lives — and livelihoods — of all Georgians,” he wrote.
In separate posts, he also said that the state was dramatically ramping up its testing capacity.
Dr. Anthony Fauci, the director of the National Institute of Allergy and Infectious Diseases, said Thursday that if he were advising Kemp, he would tell him “not to just turn the switch on and go.”
“Because there is a danger of a rebound. And I know there is a desire to move ahead quickly. That’s a natural human nature desire. But going ahead and leapfrogging into phases where you should not be, I would advise him as a health official and as a physician not to do that,” said Fauci, who is part of the White House’s coronavirus task force.
There’s plenty of opposition to Kemp’s plan in Georgia as well, and many shop owners there said they wouldn’t reopen on Friday.
Atlanta Mayor Keisha Lance Bottoms, a Democrat, told CNN in an interview that she was “perplexed that we have opened up this way.”
“I don’t know how you get a haircut and keep a safe distance from someone who is cutting your bangs, it just doesn’t make sense to me,” she said.
