The countries of comparison: Whose Corona has strategy works best?
Lockdown, Surveillance, Social Distancing, different countries chose different strategies to protect themselves from the pandemic. Usually, several measures came together. But what was particularly helpful?
You might think that Hong Kong has to be the most effective strategy against Covid-19. With a population of 7.5 million people, only four deaths have been reported, such as the magazine "Nature" writes. The country chose a Mix of Surveillance, quarantine, and Social Distancing measures. Schools were closed and many people were wearing face masks.
All of this led to the reproduction factor R, which indicates how many people are infects a of Infected in the Mediterranean, sank quickly. In the beginning of February, he was about 1. The scientists reported in a in April in the journal "The Lancet" published article.
Need to know what measures work particularly well
"Our results show that Social Distancing, and changes in the behavior of the population – the social and economic impact, which is less disruptive than a total Lockdown – Covid-19 check können", the researchers write.
However, the study to explain to authors that they could not account for in their study, which measure was out of the package especially effective. This is a question that experts are interested in is the most burning. Because if it is known what actions work to stem the pandemic, strategies can be developed to keep the Virus in check, as well as a normal life.

Therefore, researchers are working to collect global data to compare the measures taken in various countries – and thus more accurate predictions to new pandemic to phase, as "Nature" more reported.
However, this is not easy, because most of the countries selected is not a strategy, but a whole bundle, the Transmission of the Virus to contain.
Rosalind Eggo created mathematical models at the London School of Hygiene and Tropical Medicine (LSHTM). She is convinced to unravel the cause and effect of successful strategies, it is challenging, also because of the situations the Virus is met in different countries, different products. "It is really difficult, but this does not mean that we do not sollten" try it;, the scientist explains in "Nature".

Scientists take 170 interventions around the world under the magnifying glass
The LSHTM is currently working for the world health organization WHO at a platform that collects hundreds of different interventions that have been carried out worldwide. Several Teams of various scientific bodies, such as the University of Oxford or of the Complexity Science Hub Vienna (CSH), are involved. The data set can be used by anyone.
According to "Nature" has taken the Team of scientists from Vienna, 170 interventions in 52 countries, including smaller measures, such as floor stickers, the to a minimum point, and bigger steps such as school closures. The Team from Oxford has recorded 13 actions in more than 100 countries.
The Viennese scientists clusterten the investigated countries according to their interventions. In Europe, they noted, for example,
- Sweden, the UK and the Netherlands acted relatively slowly, and initially on herd immunity will be achieved. There were few voluntary measures.
- that Germany and Austria reacted in a more aggressive and early.
- France, Italy and Spain were in the comparison a little later in the respective course of the epidemic with similar measures.
The researchers from Oxford came also to the conclusion that poorer countries are imported mostly more stringent interventions than richer Nations.
"We need to the intervention in real time evaluieren", Eggo, who is not involved in the creation of the database is explained. The only way policy can be made decided what to do next. The researchers are now working. You continue to analyze the measures, in order to get more meaningful results, which of the interventions strike particularly well.
These strategies chose different countries in the fight against the Coronavirus

Later recommendations were to refrain from unnecessary travel, especially by Bus and train or to work, if possible, at home. Also, residents were of the Old – and nursing homes have no visitors.

According to the “Handelsblatt” show mobile data, however, is that the Swedes have avoided your cities recently. The news Agency Bloomberg reported that the popular tourist island of Gotland had over the Easter weekend, over 96 percent less visitors than usual. The Swedes isolate so now apparently without any official statement.
