«The Delta variant spreads like a fire»

The Delta variant currently dominates the world. On Friday, a report by the US Centers for Disease Control and Prevention (CDC) came out saying that Delta is as infectious as chickenpox and that its transmission is only slightly limited by full vaccination. – This variant is more severe. It spreads like a violent fire, doctors say.

1. The Delta variant in the United States is responsible for 90 percent. cases. In Great Britain for almost 100. Over 90 percent. participation was also registered in Denmark, Sweden, Germany, Portugal, the Czech Republic and Our Country
2. According to CDC, Delta is much more contagious, causes more serious symptoms, and increases the risk of hospitalization
3. What does the practice say? The information contained in the CDC report, in an interview with Reuters, confirms doctors experienced in the fight against coronavirus

Coronavirus: Delta variant more dangerous than the previous ones

The U.S. Centers for Disease Control and Prevention in the report stress that the Delta variant of the coronavirus, first identified in India and now dominant worldwide, is “possibly more severe” than earlier strains.

1. CDC report leaked. Delta is one of the most infectious viruses in the world

The agency cited studies in Canada, Singapore and Scotland that showed that people infected with the Delta variant were hospitalized more often than patients earlier in the pandemic.

Experts in an interview with Reuters – based on their own experience – confirm that the Delta variant is much more dangerous, but at the same time emphasize that the populations participating in the study were not very large, and the results have not yet been verified by external experts.

Doctors point out that more data and epidemiological studies involving more people are needed to determine to what extent this variant causes more severe disease.

Delta is like chicken pox

According to a CDC report, the Delta variant is as contagious as chickenpox, much more contagious than the common cold, flu, or the primary strain of the coronavirus.

Shane Crotty, a virologist at the La Jolla Institute of Immunology in San Diego, said the most specific indication the variant could cause more severe disease came from a study in Scotland that found Delta roughly doubled the risk of hospitalization compared to an earlier strain of the virus.

However, most hospitalizations and deaths from COVID-19 in the United States are among people who have not been vaccinated. But there is evidence that vaccines are less effective in people with weakened immune systems and in the elderly.

In vaccinated, healthy people, COVID-19 infection is usually asymptomatic or mild, says Dr. Gregory Poland, an infectious disease expert at the Mayo Clinic.

– But they can pass it on to family members and others who may not be so lucky – said Dr. Poland. – We must be vaccinated, otherwise we will have to deal with an increase in the number of cases for the fourth time, and this may result in further, even worse variants.

The delta spreads like a fire

– Delta is like a fire. Not like a small fire, but like raging flames, says Dr. Michelle Barron, senior medical director of infection prevention and control at UCHealth, Colorado.

Research from China shows that the Delta variant replicates much faster and generates a thousand times more viruses in the body compared to the original strain. This is the greatest threat of the new wave, says Dr. Barron.

According to other doctors, Delta-infected patients progress much faster, and some have more severe symptoms than those treated in earlier pandemic waves.

“We are now seeing more oxygen-requiring patients,” said Dr. Benjamin Barlow, chief physician at American Family Care, a network of US state clinics.

At his clinic in Birmingham, Alabama, Barlow added about 20 percent. of patients tested positive for COVID-19. A few weeks earlier it was 2-3 percent.

David Montefiori, director of the AIDS Vaccine Research and Development Laboratory at Duke University Medical Center, confirms the CDC report that the Delta variant is more contagious and leads to faster disease outbreaks, especially in unvaccinated people.

– This variant is more severe. Not only does it spread faster, it also makes the disease much more serious, says Montefiori.

Delta variant in the world

The Delta variant currently dominates the world. It is especially severe in the United States. It is currently responsible for almost 90 percent. infections, the number of which is constantly growing, on June 30, over 100 thousand were recorded there. new cases, the daily average for the last week exceeds 80 thousand. This does not translate into a large number of deaths. On average, 350 people have died daily in the last seven days.

1. Where did the first anti-vaccines come from and who were they?

In Great Britain, Delta is responsible for almost 100 percent. cases. There, the peak of the fourth wave took place in mid-June (on average, there were almost 60 cases), now the number of cases is falling (the current daily average for the last week is over 26). The number of deaths did not exceed 100 cases per day.

In Poland, according to what health minister Adam Niedzielski said on Friday, the share of the Delta variant has already exceeded 60 percent. In the last two days, the number of new cases was 91, no fatalities were recorded. The average daily number of new COVID-19 cases from the last week is 129. However, this value has been increasing for several days. On June 10, the average was 77.
