Coronavirus map and its maintenance as THL’s service has ended on 31 December 2021. The contents can be found on the new Coronavirus cases, hospital treatment situation, and deaths website.

Source: THL / National Infectious Disease Register, the latest data are from 6/9/2022.

Information in the National Infectious Diseases Register is updated with a few days' delay. The data may be updated retroactively. The information is updated on weekdays at 12 noon. Information from Saturdays and Sundays is updated the following Monday. THL updates the number of patients in primary health care, specialised medical care and intensive care on Mondays, Wednesdays and Fridays.

The tabs on the map show the incidence of the disease, and the number of cases and tests by hospital district and municipality. The upper right corner of the Incidence tab in the map view allows you to select different map layers. You can either view data from the entire period (cumulative) or from the last 14 days. By default, the map displays data from the previous 14 days. You can find an explanation of the map symbols by clicking on the menu in the upper right corner of the map. 

On the right-hand side of the map the number of cases, incidence and number of tests is shown, as well as the change from the previous reporting.  In addition, the number of patients in primary health care, specialised medical care and intensive care as well as changes in the number of patients in relation to the previous reporting day in the entire country is presented. 

The bar chart shows cases and deaths according to age group. On the chart the cases are shown according to municipality. The charts on the lower edge show tabs with each day's cases of the disease, deaths, and accumulated cases, and the daily number of tests and the number of tests for the whole period (cumulative).

Information on municipalities with 0–4 cases is not shown. Incidence refers to the number of cases in relation to the population of the region (per 100,000 residents). On the basis of the number of tests presented by each hospital district, the number of tests in proportion to the population and the proportion of positive cases have also been calculated. 

The two week incidence by municipality is calculated using two last full calendar weeks (using THL corona open data). If there are 0 - 4 cases on both weeks, no data is shown. The 14-day incidence for hospital districts is calculated for the last 14 days, excluding the most recent reporting day and the two days preceding it.
