Here, Nature explores what the science says about the months and years to come. > But exactly how much contact tracing and isolation is required to contain an outbreak effectively? An analysis by the Centre for the Mathematical Modelling of Infectious Diseases COVID-19 Working Group at the LSHTM simulated fresh outbreaks of varying contagiousness, starting from 5, 20 or 40 introduced cases. The team concluded that contact tracing must be rapid and extensive — tracing 80% of contacts within a few days — to control an outbreak. > Tracing 80% of contacts could be near-impossible to achieve in regions still grappling with thousands of new infections a week — and worse, even the highest case counts are likely to be an underestimate. A June preprint1 from a Massachusetts Institute of Technology (MIT) team in Cambridge analysing COVID-19 testing data from 84 countries suggests that global infections were 12 times higher and deaths 50% higher than officially reported (see ‘Predicting cases and deaths’). “There are many more cases out there than the data indicate. As a consequence, there’s higher risk of infection than people may believe there to be,” says John Sterman, co-author of the study and director of the MIT System Dynamics Group. > It is clear now that summer does not uniformly stop the virus, but warm weather might make it easier to contain in temperate regions. In areas that will get colder in the second half of 2020, experts think there is likely to be an increase in transmission. > Another possibility is that immunity to SARS-CoV-2 is permanent. In that case, even without a vaccine, it is possible that after a world-sweeping outbreak, the virus could burn itself out and disappear by 2021. However, if immunity is moderate, lasting about two years, then it might seem as if the virus has disappeared, but it could surge back as late as 2024, the Harvard team found.
