Czech Rep., Jan 6 (BD) – The Ministry of Health has made changes to the anti-epidemic risk index calculation. The new PES 2.0 system has replaced the parameter measuring the relative positivity of tests with a new indicator measuring the share of patients hospitalized with Covid-19 in the last 14 days who had been previously undetected. 

The new parameter recognizes the number of covid-postive patients who have been hospitalised but had not been previously diagnosed by a test or detected by tracing. 

According to the Ministry of Health, several fundamental questions remain in PES Version 2.0 to calculate the risk index, only one source-indicator has been adjusted. 

“The new parameter serves as an indicator of the detection of the infected and predictively reflects its health impact. Other parameters of the risk index remain unchanged,” said Ladislav Dušek, Director of the Institute of Health Information and Statistics.
