– Blood tests confirm that there are probably very few who have had the infection so far, says FHI. They are now asking for saliva samples from test subjects.
Blood samples from a group of 480 people in the Oslo area confirm that less than 2 percent, less than 1 in 50, have antibodies to the blood coronavirus. This indicates that only a small part of the population has been infected with the coronavirus, writes the Institute of Public Health in a press release on Friday.

Antibody studies will provide information on how many have been infected in Norway. If antibodies are found in the blood, there is evidence of infection, while a PCR test shows if you have the virus in your body or if you have had it recently. (The PCR test is taken with a swab in the nose or throat.)

The FHI-referenced antibody study was taken between 6 and 8 May with participants from the Oslo area.
– The results confirm that there are probably very few who have had an infection so far, says project manager Per Magnus of the Institute of Public Health.

DIFFERENT TESTS: PCR tests (as here in the Aker Hospital emergency room) are taken with a swab in the nose or throat. It shows if you have the virus in your body or if you have had it recently. A blood test can detect if you have antibodies in your blood and have had a covid-19 infection.

Check saliva samples
The National Institute of Public Health will now initiate more research to track the coronavirus. Test subjects must present a saliva sample, reports NTB.
Magnus says they hope to start the new tests soon. The saliva test can show if the person has the virus in their body, just as you do when you test your nose and throat with a brush.
– From the Institute of Public Health, we want to send a small package to a random sample. It contains a tube that you can spit out and send again, Magnus tells NTB.

The latest crown numbers
- As of Thursday, 232 deaths had been reported to the Institute of Public Health (FHI), which updates its figures once a day. That’s three more than Wednesday. The average age of these is 82 years. 54 percent of the dead are men. FHI states that it is not always possible to know if the patient died or with covid-19.
- 8,197 people have been diagnosed with coronavirus infection, the Infectious Diseases Notification System (MSIS) reported Thursday. On the last day, 22 new cases of infection were detected.
- The average age of those who registered infected is 46 years old. 50 percent of those infected are women.
- The infection rate, which describes how many people on average an infected person continues to transmit, was 0.49 on May 8 (for the period from April 20 to May 8). This is the last figure updated so far, as a new model is being worked on.
- A total of 61 corona patients were hospitalized on Thursday, according to figures from the Health Directorate. This is the same number as Wednesday.
- Patients are distributed as follows in the four health regions: Health South-East (40), Health West (8), Health Central Norway (9) and Health North (4).
- Thirteen patients received respiratory therapy on Thursday, two fewer than on Wednesday.
- The average age of all 218 who have entered intensive care is 62, and 74 percent are male. 37 deaths have been recorded in intensive care units.
