The European Center for Disease Control and Prevention (ECDC) observed an increase in Covid-19 cases in some European Union countries prior to arrival new optionsthough he believes there is “no indication” of an increase in hospital admissions.

In the application, the European body indicates that after a few months infection rate “very low”, transmission of Covid-19 disease “has begun to rise in some EU/EEA countries”.

Although this coincided with an increase in the discovery of pedigrees like XBB.1.5 carrying mutation F456L, like option EG.5, ECDC believes that “there are other factors that can contribute to the increase in transmission speed”.

“These include large gatherings during seasonal holidays and lower levels immune defense against infection after several months of very low incidence. There are currently no signs of an increase in hospital admissions or pressure on healthcare systems,” they said.

In any case, ECDC classified XBB.1.5-like lines with an additional F456L amino acid substitution as variants of interest due to the “rapid increase in the proportion of these options currently in circulationwhich may have immunity evasion properties compared to variants that were previously in circulation.”

Based on what has been observed in countries outside the EU, the agency considers it “probable” that the F456L variants “contribute increase transmission In the coming weeks.” “However, the resulting levels of severe disease are unlikely to reach the peaks previously seen during the Covid-19 pandemic,” they say.

They also consider it “unlikely” that variants of the F456L will be associated with an increase severity of infection compared to previously circulating variants or reduced vaccine efficacy against severe disease.

“However, as with other variants of SARS-CoV-2, older people and people with comorbidities may develop severe symptoms if infected,” they noted in this regard.

Therefore, ECDC called on Member States to increase the use and reporting of data from “well-designed and representative” population-based surveillance in primary and secondary health care in order to “track timely trends in transmission and disease serious in time, place and person.

“To the extent possible, all samples positive for SARS-CoV-2 from representative surveillance systems should be sequenced and submitted to the Global Initiative to Share All Influenza Data (GISAID) and/or the European Surveillance System (TESSy) to facilitate the assessment of circulating options,” he said.

Finally, they argue that adherence to national vaccination schedules is “necessary to protect people with risk of serious illness and death“. “Countries should assess whether they are ready to identify target groups and timely conduct vaccination campaigns against Covid-19. In addition, communication campaigns aimed at the public and healthcare workers are considered necessary to reach high-risk groups and inform them of the importance of timely vaccination,” he stressed.
