At least 151,000 people in the United States have been fully vaccinated against Covid-19, according to a New York Times survey of all 50 states. 7 дней назад
It typically takes a few weeks for the body to build immunity (protection against the virus that causes COVID-19) after vaccination. That means it’s possible a person could be infected with the virus that causes COVID-19 just before or just after vaccination and still get sick.
Caution is advised for anyone who has a history of serious allergic reactions to vaccines or injections in the past. Out of millions of doses administered to date, very few severe side effects, including allergic reactions, have been reported. No long-term adverse effects have been reported.
While the COVID-19 vaccine isn’t necessary to fly yet, some high-risk nations require specific immunizations to enter the country. For example, it’s typical for many countries in Latin America, Asia and Africa to require the Yellow Fever vaccine.
SARS-CoV-2 RNA has also been detected in other biological samples, including the urine and feces of some patients. One study found viable SARS-CoV-2 in the urine of one patient. Three studies have cultured SARS-CoV-2 from stool specimens. To date, however, there have been no published reports of transmission of SARS-CoV-2 through feces or urine.
Research is still ongoing into how strong that protection is and how long it lasts. WHO is also looking into whether the strength and length of immune response depends on the type of infection a person has: without symptoms (‘asymptomatic’), mild or severe. Even people without symptoms seem to develop an immune response.
There is some evidence that COVID-19 infection may lead to intestinal infection and be present in faeces. However, to date only one study has cultured the COVID-19 virus from a single stool specimen. There have been no reports of faecal−oral transmission of the COVID-19 virus to date.
“In other words, a vaccinated person might still be able to spread the virus, even if they don’t feel sick.” Until researchers can answer that question, Frieden said, wearing masks is the safest way for vaccinated people to protect those around them. 2 дня назад
For now, the CDC recommends that people not assume they are completely immune to infection after having been vaccinated. Overall, both vaccines provided about 95% protection in clinical trials — so a small number of people might still catch the virus even after two shots.
People of all ages can be infected by the new coronavirus (COVID19). Older people, and people with pre-existing medical conditions (such as obesity, asthma, diabetes, heart disease) appear to be more vulnerable to becoming severely ill with the virus. WHO advises people of all ages to take steps to protect themselves from the virus, for example by following good hand hygiene and good respiratory hygiene.
Swimming in a well-maintained, properly chlorinated pool is safe. However, it is advisable to stay away from al crowded areas including crowded swimming pools. Keep 1 metre distance from people who sneeze or cough even in a swimming area.
COVID-19 can be characterized as a pandemic. This is due to the rapid increase in the number of cases outside China over the past 2 weeks that has affected a growing number of countries.
Посмотреть полный ответ At the time of preparing this Q&A, there are no peer-reviewed studies that have evaluated the risk of SARS-CoV-2 infection associated with smoking. However, tobacco smokers (cigarettes, waterpipes, bidis, cigars, heated tobacco products) may be more vulnerable to contracting COVID-19, as the act of smoking involves contact of fingers (and possibly contaminated cigarettes) with the lips, which increases the possibility of transmission of viruses from hand to mouth. Smoking waterpipes, also known as shisha or hookah, often involves the sharing of mouth pieces and hoses, which could facilitate the transmission of the COVID-19 virus in communal and social settings.
The COVID-19 pandemic, also known as the coronavirus pandemic, is an ongoing pandemic of coronavirus disease 2019 (COVID-19) caused by the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which was first identified in December 2019 in Wuhan, China. The outbreak was declared a Public Health Emergency of International Concern in January 2020, and a pandemic in March 2020.
Hotels and other accommodations should have procedures for cleaning, disinfecting and ventilating the room properly between every guest’s stay. These processes allow the accommodations to be used immediately afterward. If these procedures are followed, there is no need to leave the room empty between guests.
