No districts in the Czech Republic are at risk of community transmission

The Ministry of Health has updated its map of alert levels based on the risk of COVID-19 contagion. The alert levels are based on the current epidemiological situation. Districts in the Czech Republic are largely white, meaning the risk is negligible, while Prague and Frýdek-Místek remain green (without risk of community transmission but with the incidence of local outbreaks).

After the 33rd week (for the period of 7 August to 13 August 2020), most districts are white with zero risk of contagion. There are 2 districts in the green zone with incidence of contagion without community transmission in the Czech Republic, those being Prague and Frýdek-Místek. Currently, the highest number of people with COVID-19 per 100,000 inhabitants is in Frýdek-Místek (244.1 per 100,000), with less in Prague (107.5 per 100,000). The highest number of newly diagnosed cases per 100,000 inhabitants in the past 7 days was again registered in Frýdek-Místek (60.1 per 100,000), with less in Prague (34.8 per 100,000).

“The situation in the Czech Republic is stable and there is no community transmission. Local outbreaks consist largely of asymptomatic cases or patients with mild forms of the disease. The situation is under control in those areas with increased incidence of contagion, vulnerable population groups have not been affected, and the number of hospitalised patients is not rising. The second and third levels of risk have still not been applied anywhere. Only Prague and Frýdek-Místek remain green. We are continuously monitoring the situation and evaluating further measures,” said Chief Hygienist Jarmila Rážová.

Prague Capital City is still classified among districts with alert level I because of the relatively high 7-day cumulative incidence per 100,000 inhabitants and the consistent number of diagnosed patients in the course of the week. Alert level I was issued for Prague as the risk trends are not escalating and there is no apparent rise in the risk for vulnerable population groups. The issuing of this alert level is an expert decision taken by the Prague Public Health Authority and the Chief Hygienist of the Czech Republic.

The epidemiological situation has generally calmed down in the Moravian-Silesian Region, and indicators show a declining trend. Frýdek-Místek has returned to daily diagnostic detections of below 20. Karviná is entirely stable, with only sporadic, single-digit daily detections. Alert level I was issued for the Frýdek-Místek district. This is an expert decision by the Moravian-Silesian Regional Public Health Authority and the Chief Hygienist of the Czech Republic.

The alert levels are primarily published as an information service for citizens and an early warning system for the changing epidemiological situation. A total of 25 parameters derived from weekly summaries of daily monitoring are evaluated. The final decision on an alert level for a given area is made based on the expertise of epidemiologists and hygienists. A significant role is played by the assessment of the risk of community transmission, meaning the risk of uncontrolled spread through the population during which the respective regional public health authority cannot determine the origin of a substantial number of the detected contagions.

The system, which identifies the individual districts according to the degree of COVID-19 contagion, is divided into four alert levels – white, green, yellow, and red – and is known as the traffic light system.  White means minimal risk, green indicates the incidence of contagion without community transmission in CZ, yellow indicates incipient community transmission, and red means rising or lasting community transmission in CZ. The Ministry of Health of the Czech Republic updates the map of alert levels on a weekly basis.
