Daily coronavirus infections have risen by the highest daily amount in a month, while some researchers raised concerns that the official ‘coronavirus dashboard’ is not registering all instances.

On Monday, the RIVM reported 185 new positive tests, on Sunday there were 144 while on Saturday there were 127, reports NOS. Andreas Voss, a professor of infection prevention at Radboud teaching hospital in Nijmegen, and member of the Outbreak Management Team, told NPO Radio that the rise was ‘to be expected after relaxing the lockdown’ and predicted more hospital admissions in four or five weeks.

However, Marino van Zelst, a student at Tilburg University, told the NRC that he believes 264 too few infections have been measured this month by the dashboard. The paper reports that this dashboard is judged a crucial weapon by the government to measure how far to continue relaxing controls – or whether to impose new ones.

Van Zelst claimed that the problems were related to corrections of previous faults in the numbers.

A spokesperson for the RIVM confirmed that there are corrections of the numbers, but told the paper that the number of positive tests reported depended above all on people’s willingness to get the test.

Last week, the RIVM reported that more than eight in 10 Dutch people with cold symptoms are not requesting a corona test, although a fifth are staying home.
