3/4 US children have had Covid-19, antibodies can last up to 2 years

According to the news agency Reuters, The CDC emphasized that it was the wave caused by the Omicron mutation that contributed to the rate of people infected Covid-19 in this country increased in a short time.

According to the data, Omicron increases infections at all ages, with children and adolescents – many of whom are still unvaccinated – having the highest rates; while the group over 65 years old – with the highest vaccination rate – got the least disease.

Between December 2021 and February 2022 – the period when Omicron rages in the US – the number of children 11 years of age and younger with Covid-19-related antibodies increased from 44.2% to 75. ,2%; 12-17 years old group increased from 45.6% to 74.2%.

The scientists emphasized that they were only looking for the type of natural antibodies produced during infection with SARS-CoV-2, excluding antibodies caused by vaccines. The good news is that trace amounts of these antibodies can stay in the blood for up to 2 years.

However Reuters also quoted a note from Dr. Kristie Clarke from the CDC, co-author of the study: “Having antibodies produced by an infection does not necessarily mean that you are protected from future infection. We do not provide protection against future infections. look at whether people have sufficient levels of antibodies to help protect against reinfection or serious illness.”

According to CDC director Rochelle Walensky, in the past week, the number of Omicron cases increased by 22.7%, the number of hospitalizations increased by 6.6%, but the number of fish deaths decreased by 13.2% compared to the previous week. Previously, some parts of the United States reported facing a new wave of subtype BA.2.12.1, which can spread about 27% faster than BA.2 but shows no difference in virulence (potentially) potential for serious illness).

WHO: The number of Covid-19 deaths last week fell to the lowest level since the beginning of the pandemic

Another good news about the pandemic has just been announced by the World Health Organization (WHO), showing that the global number of deaths from Covid-19 has dropped to the lowest level since March 2020. According to CNBC, WHO data shows that the world recorded 15,668 new deaths in the past 7 days, down much from the 18,000 reported in the week ended April 17.

WHO Director-General Tedros Adhanom Ghebreyesus said that some countries have reduced Covid-19 testing, which limits WHO’s ability to track the impact of the virus globally. He suggested that we should “cautiously welcome” good news about Covid-19. He called on countries to maintain a Covid-19 surveillance system, including testing and sequencing the SARS-CoV-2 genome.
