Hungarian research finds clear correlation between lockdown, falling death rate

Hungarian scientists analysing publicly available iPhone data to gauge the effects of lockdowns have found a clear correlation between their severity and speed and the decline in the death rate.

Hungarian researchers of the Eötvös Loránd University, the Eötvös Research Network’s Ecological Research Centre (ELKH OK) and Australian researchers examined publicly available mobility data during the first wave of the coronavirus pandemic in Belgium, the United Kingdom, France, the Netherlands, Germany, Italy, Spain, Switzerland and Sweden.

The study published in the Jan. 18 edition of Nature Magazine’s online Scientific Reports found the Covid death rate was linked to how swiftly lockdowns were ordered and the extent to which people observed them.

Generally, mobility fell sharply when lockdowns were introduced before levelling off, though there were differences between the lockdown practices of various countries,

the study’s co-author István Scheuring said in a statement. The severity of the lockdown, which correlates closely with the mobility data, was a key indicator of the number of deaths during the first wave, Scheuring said.
