Uruguay has been a rare bright spot in coronavirus–ravaged South America, thanks to a highly developed research infrastructure, a tradition of at-home medical care, and a strong public health system. Two key advisors to the government’s pandemic response team explain how they scaled up their tests so fast and why they are now encouraging people to go outside more.

The first cases in Uruguay were confirmed on March 13, and the national working group that we convened of about 60 people met with the president on April 16. There were two main arms, one in health and one in data science and modeling.

The number of cases never really built up to the point where we had no control. You could almost track our epidemic through five or six distinct outbreaks that we’ve had, all with around 50 to 60 cases, and they’re all basically isolated. The most recent outbreak was in a province called Treinta y Tres that is close to the Brazilian border, and this was the second outbreak we had of Brazilian origin. That border is technically closed, but there are some border towns which are binational, so it’s hard to enforce. Actually, the main street in one of these towns is the border. So people will just cross freely. You cannot really be as locked down as we would like in those border towns.

Right now there’s a reasonably good capability of PCR testing. [Editor’s note: polymerase chain reaction, or PCR, is the standard method of identifying a virus from its genetic material.] We have built up enough capacity that if there’s any outbreak, we can do contact tracing not just of the immediate contacts, but even second-order contacts. We’ve been doing that, plus some random testing of people around outbreak hot spots. As for the people who actually do the field testing, we have been relying on the existing capacity of the health ministry in terms of infectious diseases. We are used to dealing with other kinds of epidemics, like dengue, and so far we haven’t had a high enough number of cases to involve people outside their expertise. But it’s not really high tech. These guys are doing the job as it has long been done: lots of phone calls.

There was an early scientific response even before the disease arrived in the country in terms of interacting with research networks around the world and sharing reagents with different universities and centers abroad, such as the University of Hong Kong and the Pasteur Institute in France, to generate molecular biology tests here. Our first tests emerged from an agreement between the University of the Republic, a local affiliate of the Pasteur Institute, and our central government.

One specific thing we have here that is perhaps not so common around the world is that we have a lot of home-based medicine. We can tell people to stay at home and the doctor will come to you– not a paramedic, an actual doctor. So nobody really went to the hospital at the start of the pandemic, and there was no dissemination [of the virus] there. The testing teams went directly to people’s homes with all the equipment on them, and they did the sampling there. That was a key factor, I think, in keeping the initial outbreak under control.
