Portugal to carry out immunity tests

Portugal will carry out studies to find out what proportion of the population has acquired immunity to the new coronavirus (SARS-CoV-2,), with the methodology and the date being considered by the international scientific community, announced the Director-General of Health.

"Yes, Portugal is going to do serological studies to find out what proportion of its population has acquired immunity to this virus", said Graça Freitas at a press conference.

The Director-General of Health said that the National Institute of Health Doctor Ricardo Jorge, together with other countries, will proceed to immunity tests, with “how can these tests be done and when is the ideal time” being studied.

“Immunity is something that takes time to settle, that is, between the date of infection and the date when our body starts producing visible antibodies for a long time to wait. It seems like a long time ago, but the disease in Portugal started about a month ago ”, she said, stressing that most Portuguese patients are still in the recovery phase.

Graça Freitas explained that the Ricardo Jorge Institute, in collaboration with scientists, academics and DGS, will enter a pilot phase with other countries, to understand what is happening.

"We will have to understand the ideal time to do the test, because if it is too early, there may still be no antibodies and, therefore, we have to find the ideal date here", he said, stressing that the methodology and the date that the studies are going to be carried out "are now being considered by the international scientific community".

Graça Freitas also said that the studies will probably have to be repeated, "to see the duration of immunity".

“It is not enough to test it once, it is necessary to know whether this immunity is lasting or not. The history of this virus is very short, we have to wait for the time to pass to find out more ”, he said.

The new coronavirus, responsible for the covid-19 pandemic, has already infected more than 1.2 million people worldwide, of whom nearly 60,000 died.


I am convinced I have had covid19. I was in Faro hospital (they where fantastic). I still think I had it & came through it. I would be willing to be on a test program. Regards, Rosemary

The last sentence is not correct. It is the REGISTERED cases of infection. Many of those who were diagnosed via phone and stay at home not even included nor the vast majority that never were registered. So the total number of infections is multiple times of what this sentence says.

During these difficult times it is important to be correct in reporting...

So how will that work? Testing every resident?
