HS’s revamped, daily updated graphics show the development of corona infections from the summer onwards in individual municipalities and hospital districts.
For a moment the direction already had time to look right in Helsinki. In late October, the incidence of new coronavirus infections in the capital began to decline.
In a couple of weeks, the incidence dropped from more than 130 to less than a hundred. Incidence refers to the number of new coronavirus infections reported per 14,000 population over a 14-day period.
Then the good development stopped, and the infections started to grow again. According to Friday’s data, the incidence in Helsinki was more than 150.
The data is reflected in the new graphics of HS. The graphics now offer municipality-specific historical data with an accuracy not previously available.
About the graphics It is also clear how Espoo and Vantaa passed Helsinki in the event of the moon at the turn of the month. Currently, the incidence rate in Vantaa is one of the highest in Finland, about 170 according to Friday’s data.
You can also add neighborhood information to the line graph by tapping the municipalities below the graphic. In addition, from the graphics drop-down menu, the reader can add to the graphics any municipality for which infection information is available.
Health and the Department of Welfare (THL) does not report data on municipalities where infections have been reported to the Communicable Diseases Registry since less than five since the beginning of the epidemic.
Municipal infection data only appear in the graphics when daily data has been accumulated long enough. For example, calculating a 14-day incidence requires data from 14 days.
For this reason, for example, data from Sodankylä are not yet in the graph, although a total of 53 infections had already been reported in Sodankylä by Friday. Most of the infections have been reported to the Infectious Diseases Register in recent weeks.
Information by hospital district
HS’s new the graphics allow data to be viewed not only by municipality but also by hospital district. Both data can be viewed in terms of both population and absolute number of cases.
For example, the graph below shows the number of cases of coronavirus infections reported in hospital districts.
The Helsinki and Uusimaa Hospital District (Hus) has clearly had the highest number of infections.
After infections the number begins to look at in relation to the population, the situation looks different.
The graphics below clearly show how big a corona cluster Vaasa was in October. The number of infections in relation to the population in the Vaasa Hospital District in October was from time to time more than four times higher than in the Hus area.
The graphics also show how quickly the situation in Vaasa has come under control. In November, the incidence in Vaasa has already been clearly lower than in the Hus area.
Graphics also offer the reader many opportunities to explore exactly the areas in which he is interested. In the graphs above, you can tap to display as many hospital district data as you want.
For example, by tapping the Lapland Hospital District button, you can see how the incidence in Lapland has surpassed the incidence in the Vaasa Hospital District in recent days.
Beware of inferences
Many graphs let you choose whether you want to view absolute numbers of infections or figures relative to population. Selections can be made from the buttons at the bottom of the graphic, such as in this graphic.
From the graphics above, it is well illustrated that even in small localities, even minor infections raise the incidence very high for a moment.
At the end of October, the incidence in Närpiö fluctuated in more than 350, which is considerably higher than in the Helsinki metropolitan area. When you tap the absolute infections from the graphics, notice that in Närpiö there were on average less than three new infections a day at that time.
Thus, Närpiö’s situation was not necessarily as bad as could have been inferred from the mere occurrence.
The incidence rate is therefore the best indicator for examining the situation of rather large municipalities.
This is how the data is calculated
Municipal and Medical records Historical data is based on THL data recorded daily by HS. THL publishes daily open data the total number of infections since the beginning of the epidemic in each hospital district and in those municipalities where there have been at least five infections.
Based on this total amount of data stored daily, HS calculates daily data for municipalities and hospital districts into graphs. Sometimes municipalities correct the data retrospectively, and for example, the total number of infections may thus decrease compared to the previous day.
The daily figures for municipal hospital districts are available in HS’s graphs for municipalities from June at the earliest, for hospital districts from August, ie after HS has stored the figures reported daily by THL in its database.
