Covid-19 reinfections are rare unless you are over 65 years of age

by

The study, which examined reinfection rates among 4 million people in Denmark, found that most people who have had Covid-19 appeared to have protection against reinfection for more than six months. At a follow-up after six months, the study found no evidence that protection decreased. But a check on the demographics of those re-infected showed that they were mostly people aged 65 and over, Jen Christensen reports.

The older age group had only 47% protection against repeated infection, compared to younger people who appeared to have 80% protection against reinfection, the team wrote. The finding is not entirely unexpected, as as people age, their immune systems weaken.

“Given what is at stake, the results emphasize the importance of people adhering to the measures implemented to keep themselves and others safe, even if they have already had COVID-19,” he said. say the co-author of the study, Dra. The Danish Institute said in a statement.

These tips are not being heeded in some parts of the United States, where governors are lifting measures to prevent their spread. Although nearly one in eight Americans is fully vaccinated, the country may be on the verge of a second increase, after the numbers of cases that declined in recent weeks appear to be declining.

Chicago officials earlier this month increased the indoor capacity of bars, restaurants and other businesses, while Baltimore leaders said yesterday that they were easing restrictions on places such as religious facilities, retail stores, malls. and fitness centers.

“We are in a race to vaccinate the population,” Dr. Richard Besser, a former acting director of the Centers for Disease Control and Prevention (CDC), told CNN on Wednesday. “At the same time, we are fighting against the exhaustion of the people with the restrictions that public health has set and we are fighting against the decision of so many governors to remove the restrictions that protect us all.”

Q: I have a high BMI and meet the requirements for the vaccine. Does that mean I’m unhealthy?

A: With obesity as a factor in eligibility for the Covid-19 vaccine, many Americans are debuting to find out their body mass index or BMI. But experts say the meaning behind these numbers – and how to reduce them – is not always so clear.

The CDC lists obesity as an underlying medical condition and defines it as a person who has a body mass index of between 30 and 40.

Having a BMI above 30 can lead to serious health problems, such as diabetes and cardiovascular disease, and obesity increases the risk of having a more severe reaction to Covid-19.

Having a high BMI, however, does not necessarily mean that you are not healthy. There are rare cases where a healthy person may have a seemingly unhealthy BMI. This includes weight trainers and people with athletic exercises who have a lot of musculature, which creates a high number of BMIs, said Dr. Caroline Apovian, co-director of the Weight Management and Wellness Center at Boston’s Brigham and Women’s Hospital. , Massachusetts.

If you’re not sure if your high BMI is due to fat or muscle, Apovian recommends that you visit a weight loss specialist for more specific tests.

Covid-19 expelled hundreds of Africans from Guangzhou. A generation of mixed race children is their legacy

The EU continues to attack AstraZeneca when it reveals vaccine passports

European Commission President Ursula von der Leyen attacked AstraZeneca for alleged underproduction and under-delivery, blaming them in part for the slow deployment of vaccines in Europe.

This comes as the EU drug regulator prepares to issue guidelines on vaccine safety after many countries have suspended its deployment following reports of blood clots. The regulator has already said there is no evidence of any link between AstraZeneca’s shootings and clots.

Von der Leyen stressed that he relied on the Covid-19 vaccine from Oxford / AstraZeneca, but warned that an export ban that the EU introduced during its recent row with the pharmaceutical company could be used if it believed other countries they did not export enough vaccines.

The EU also unveiled its proposal for a “digital green certificate”, or vaccine passport, that would allow safe and free movement within the bloc during the pandemic. The certificate confirming that a person has been vaccinated against Covid-19, has received a negative test result or has recovered from Covid-19 can be used in all 27 Member States.
