They joined to a lesser extent than expected. The response of the citizens selected by Istat to carry out the serological tests disappoints, as part of the national survey aimed at mapping the spread of the new coronavirus on the territory. Of the sample of over 150,000 subjects selected in 2 thousand municipalities and all contacted by the Red Cross, only 24% responded positively to the first contact and of these more than half have already taken the sample. A 63% of people are instead to be contacted because, for various reasons, has not yet responded. Finally, 13% expressed a temporary refusal, which CRI will try to “transform into positive responses”.

Covid, in the swabs less virus particles: merit of the masks
Virus, the bulletin: new infections (280) and deaths (65) on the rise. 70% of cases in Lombardy

Insufficient adhesions that led to the decision to extend the investigation, which started on May 25 and which was due to last two weeks, until the end of June. There are various causes for the lack of enthusiasm of the Italians, starting from the fear of having to carry out an undefined quarantine period. Meanwhile, to provide a first photograph of the spread of the virus in one of the most affected areas is another investigation, again with serological tests, promoted by the Ats Health Authority of Bergamo: from April 23 to June 3, 20,369 people were tested , of which 9,965 citizens and 10,404 health workers. For citizens, the percentage of positivity is 57%, while among healthcare workers it drops to 30%. The survey provides a first territorial picture of the ‘quantity’ of citizens who have developed antibodies to the virus. The goal, with the national survey, is to extend the mapping to the whole territory. The times, however, will inevitably lengthen at this point. “Honestly – said the vice president of the Red Cross Rosario Valastro – we expected more adhesions, more than anything else because there had been a great popular mobilization”.

Among the explanations of the low availability of citizens to undergo tests, “we have paid the price for an escalation of fake news on social media, an excessive presence of varieties of tests, some of which have since been withdrawn from commerce, while these are currently the safer, and then also because of incomplete information, since the communication campaign was launched in parallel with the start of the calls. So much so that then the membership has gone up a little “, argues Valastro. But above all, it is the lack of certain times between the serological test and the administration of the swabs that weighs: precisely «uncertain times represent a recurring fear. We asked the Ministry of Health in this regard at the common table – he specified – but this probably depends on the territorial differences ». When the citizen receives the results of the serological test, the presence of antibodies is reported to the healthcare company that imposes the quarantine on the person until a swab is made which will reveal if it is positive or negative.

But as for the timing of the entire procedure, “we – Valastro pointed out – we cannot give any deadline because it depends on the regional health systems, so we do not know the times within which citizens are then subjected to the swab”. For this reason, a new appeal comes from CRI to the selected Italians: «The appeal we launch to those who have received a pre-alarm text message is that when the calls arrive, they know that it is not advertising or anything else, it is a withdrawal made in an accredited facility and within 15 days you will have the results of the presence or absence of antibodies ». But how do you recognize that it is not a scam? The calls, recalls the Ministry of Health, come from the Red Cross number whose first digits are 06.5510, and this number is also included in the spot that will be broadcast on Rai networks.
