Most want masks made compulsory on Swiss public transport, suggests survey

On 13 May 2020, Switzerland’s government published more information on the Swiss Proximity Tracing App (Swiss PT), an app designed to slow the spread of SARS-CoV-2. Developed by teams at EPFL and ETHZ, the app uses Bluetooth to detect when your phone comes within two metres of another phone or device with the app. It then records the contact as an anonymous key and the duration of contact, flagging any close contact longer than 15 minutes.

Italy is preparing to reopen its borders with the rest of Europe, according to the newspaper La Repubblica. A draft law on new rules was published on 15 May 2020 by the Italian Council of Ministers. It provides for the possibility of allowing entry to Italy from 3 June 2020 without requiring those arriving from certain countries to quarantine for 14 days. The countries include EU nations and Schengen members, including Switzerland and Monaco.

Lombardy, the region in northern Italy where the coronavirus outbreak first took off in Europe, now has fewer per capita cases testing positive for the virus than some Swiss cantons. Recent data from Italy show there were 179 cases per 100,000 in Lombardy. In Ticino, Switzerland’s worst affected canton, there were 329 cases per 100,000. Geneva (231) and Vaud (211) had Switzerland’s next highest rates.

Coronavirus testing has been rationed in Switzerland, reserving it for high risk more severe cases, although doctors retain discretion to have anyone tested. It is likely those that have been infected and have recovered will have immunity and no longer be able to act as carriers of the disease.

This morning, Switzerland’s federal government announced the number of Covid-19 tests conducted so far in Switzerland. South Korea, a nation often cited among those with high test rates, now trails Switzerland on the number per capita tests it has conducted.

While there is currently no scientifically proven link between anosmia (loss of smell) and Covid-19, more and more experts are saying the symptom is a strong indicator. Gilbert Greub, head of the microbiology department at the CHUV hospital in Lausanne, is one such expert. “Given the widespread Covid-19 epidemic, I think that everyone who has a problem tasting or a problem smelling has a very high likelihood of testing positive and should be tested.

By 31 March 2020, there were around 326 Covid-19 patients in intensive care and 228 on ventilators in Switzerland. It is estimated that there are around 750 ventilators across the country. If the health system reaches overload, medical professionals in Switzerland might be forced to make the kinds of difficult decisions being made in neighbouring France and Italy.

As Switzerland moves towards easing Covid-19 social restrictions, some fear the virus will get away again. A key part of containing the spread is testing. One way to evaluate how comprehensive testing is is to look at positivity, the percentage of tests that are positive.
