The Covid this year does not give up even in summer, with all due respect to those who thought that the heat could slow down contagions (and the number of deaths): both theRt index (1.30) both the incidence of cases (763 per 100 thousand inhabitants), and the hospitals reorganize themselves to reactivate those specialized departments reserved for infected people, such as, for example, the San Giovanni hospital in Rome which reopens another Covid ward, while the number of entries in the intensive therapies.

A sad picture that has recurred too many times in the last two years, and begins to alarm those who fear that they have been infected or recontacted due to the new variant of the virus, Omicron 5, which is proving to be very infectious. And a new hunt for tampons has started, a test that Fr.the rest could give way to new patches capable of detecting antibodies to the virus.

New patches instead of tampons

The result of the test is guaranteed in about three minutes: this is the perspective that emerges from a study by scientists from the University of Tokyo, who have developed a new method to detect specific antibodies for the new coronavirus, capable of verifying the presence of a Covid infection in a safe, reliable and non-invasive way, thanks to a special patch that is applied to the skin. And the study was published in Scientific Reports.

The ineffective identification of Covid-infected individuals has severely limited the global response to the pandemic, the authors explain. At the same time, the high rate of asymptomatic infections, which according to current estimates would be between 16 and 38%, has multiplied the difficulty of identifying positive cases and breaking the chains of contagion.

Omicron 5, Iss: Rt and intensive care hospitalizations are still growing, few infections detected by contact tracing

Omicron 5, who are the new positives? Admissions only for unvaccinated and over 65. “But the symptoms have changed”

“Alarm of submerged cases related to do-it-yourself tests”

The number of swabs processed to detect infections by Covid. And at the same time the number of “hidden cases” linked to do-it-yourself tests is growing. “In Italy we are witnessing an increase in contagions certainly also the result of the variant Omicron 5 – argued just a few days ago the national secretary of Federfarma, Roberto Tobia – There is therefore a resurgence of the virus that is raising its head. A fact that worries us, it being understood that this rise was coupled with an increase, albeit in a lower percentage, of tampons carried out in pharmacies Italian. The difference, and this alarms us a lot, is the do-it-yourself kits for the Covid test at home. A phenomenon that dissuades people from swabbing in public facilities or pharmacies and that creates a hole in the tracing of cases: so many infections are so submerged “.

The prices of tampons

With the end of the state of emergency, the prices of quick tampons in pharmacies for adults have remained stable, but there have been increases for children. From the survey carried out by Altroconsumo the day after the expiry of the state of emergency, which ended, we recall, at the end of March, and which sampled over one hundred pharmacies in 10 regions, it emerged that the price of a rapid test for adults it remained almost everywhere at 15 euros, while for minors between 12 and 15 years it went from 8 euros set by the emergency protocol to almost 13 euros on average. During the state of emergency, however, by virtue of the agreement between the government and pharmacies to limit the prices of tampons, for minors between the ages of 12 and 18 the amount was set at 8 euros. Then there are rapid tests carried out in pharmacies capable of measuring the viral load, and here the price rises: in Rome, for example, the amount is 22 euros..

Much cheaper, however, are the prices of do-it-yourself tests, with prices ranging from 3 to 10 euros.

The difference between rapid antigen tests and molecular swabs

THE rapid antigen tests (so-called quick swabs) and i Pcr molecular buffers they represent two distinct types of tests that aim to identify the presence of the SARS Cov-2 virus.

THE quick swabs are based on the search, in respiratory samples, for surface viral proteins (gly antigens) and guarantee a response within minutes of collection. The sensitivity of rapid antigen tests, however, is lower than molecular swabs in patients who have a low viral load, and could give rise to “false negatives”. Furthermore, a positive result in the rapid test requires a confirmation test performed in the laboratory with the molecular technique (molecular buffer PCR). Rapid tests are believed to be less reliable in symptomatic patients who have developed the disease less than 5 days ago, or after the seventh day after the onset of the first symptoms.

Molecular tests Pcr, golden strandard test (maximum value in terms of reliability and efficacy) by the WHO, detect the presence of viral genes from Covid in the body. Response times are up to 48 hours from the time the test is performed, with reliable and timely reports. Molecular tests minimize false positives.
