Coronavirus continues to mutate, having 8 variants globally

The new strain of coronavirus, which is causing the pandemic, continues to mutate and there are 8 variants that are spreading globally, health experts said.

Scientists are studying the genome of the coronavirus and discovering new strains have emerged, since the virus first jumped from animals to humans at China’s wildlife meat market late last year, according to New York Daily News .

The good news is that the new variants are not more lethal, says Trevor Bedford, owner of , a site that tracks the genome of viruses from samples sent from around the world.

The new variants are thought to be no more fatal, according to experts.

The results “show how the virus spreads and divides into other similar strains,” USA Today explained.

“Literally, if the question is ‘whether the virus is genetically altered’, then the answer is yes,” Harvard epidemiologist Marc Lipsitch told NPR .

“The question needs to be asked whether there are any significant changes to the course of the disease or the likelihood of transmission of the disease, or other things we are concerned about.”

The new variants are only slightly different, with no change in the level of lethality, experts said.

“The currently recorded mutation rate, about two variants per month, is perfectly normal for the virus,” Bedford wrote on Twitter. “Flu and the common cold have similar mutations. Even flu. even faster mutations. ”

The genomes recorded so far are providing the information needed to predict whether viruses can be prevented, and whether social strain orders will work. But the picture of the virus is still a sketch, experts say.

They agree that there is still much to discover. But for the time being, micro-level variations are helping researchers map the spread of pathogens around the world.

“The outbreaks can be traced,” Charles Chiu, a professor of medicine and infectious disease at the University of California, San Francisco Medical School, told USA Today. “We have the ability to decode the genome in real time to see which strains or variants are spreading.”

  • WHO updates mask recommendations

    Now they are advised to wear not only sick.

    WHO Director-General Tedros Hebreyusus, at a new briefing on COVID-19, announced new recommendations for the prevention of coronavirus. Here are the main points:

    • Doctors and other medical staff should always wear masks, regardless of whether they work with infected coronavirus infections or not.
    • People over 60 years of age, as well as those who have chronic diseases, are advised to wear masks wherever it is impossible to maintain physical distance.
    • The governments of the countries should encourage the wearing of masks in any places where it is impossible to maintain physical distance, especially for public transport and shops.
    • Those with symptoms similar to coronavirus infection should stay at home. All who contacted him should be quarantined.
    • If a sick person or someone who has contacted him needs to leave the house, he must wear a mask.
    • WHO considers masks to be of high quality, which consist of three layers of different materials or more.

    Previously, the WHO spoke only about the need to wear masks for patients who were ill, because there was insufficient data (apart from clinical studies, which many experts consider to be of little relevance to real life).

  • WHO recorded 106,000 new infections globally in 24 hours

    The WHO recorded 106,000 infections in 24 hours, a record day since the outbreak, with two-thirds of these cases recorded in only 4 countries.

    Tedros Adhanom-Ghebreyesus, Director General of the World Health Organization (WHO), said on May 20 that the number of coronavirus infections reported to the agency in the past 24 hours has been higher than at any time since outbreaks, according to CNN.

    “We still have a long way to go in this pandemic,” Tedros said at a news conference in Geneva, Switzerland. “In the past 24 hours, 106,000 cases have been reported to WHO – the highest daily level since the outbreak.”

    “About two-thirds of these cases have been reported in only four countries,” he added.

    According to WHO epidemiologist Maria Van Kerkhove, confirming with CNN via email, these four countries are the US , Russia, Brazil and India.

    It should be noted that there may be a delay in reporting the number of cases at various points in the process, so the above date record does not mean that these 106,000 people were infected, tested or statistically counted in the last 24 hours.

    According to the constantly updated data of John Hopkins University, the world has recorded nearly 5 million cases of coronavirus, of which more than 326,000 people have died. The United States remains the leading country in both cases – more than 1.5 million, and deaths – more than 93,000.

    Notably, Russia has recently become the second country in the number of cases – more than 308,000, although only a few weeks earlier did not even make the top 20 of the list. Brazil also climbed rapidly in the ranking, ranking third in the number of cases – more than 271,000.

    Russia is ranked second in terms of deaths – more than 35,000, followed by Italy – more than 32,000, France – more than 28,000, Spain – more than 27,000.

  • Brazil has most deadly day of epidemic, patients do not have enough breathing machines

    Brazil recorded the highest number of Covid-19 deaths since the outbreak, as coronavirus continues to exert a heavy influence across South America.

    According to the Guardian , the number of deaths due to the coronavirus recorded on May 19 in Brazil is 1,179, the highest number of deaths per day since the outbreak in the country. Earlier, the highest number of deaths in 24 hours due to the disease was recorded on 12/5 with 881 cases.

    Brazil has also officially overtaken the UK in the number of cases to become the 3rd largest outbreak in the world. The South American country has recorded 271,628 cases positive for coronavirus, an increase of 17,408 cases compared to the previous 24 hours.

    Other South American countries also noted the heavy impact of Covid-19. As in Brazil, many cities in South America report deaths due to don’t have enought breathing machine.

    Chile is facing the risk of collapse of public health system due to overload. More than 90% of the intensive care beds in Chile’s capital Santiago have been mobilized to treat Covid-19 patients. The city cemetery had to dig 1,000 emergency graves urgently to prepare for the “wave of death” approaching.

    In the Peruvian capital Lima, cases of Covid-19 infections account for 80% of the intensive care beds. “We are in a bad situation, this is a war,” said Pilar Mazzetti, who heads the Peruvian government’s anti-Covid-19 task force.

    Public health organization Pan American Health said there was growing concern about the risk of virus spreading in the border areas between Brazil and Colombia and Peru. The organization calls on regional authorities to step up measures to protect vulnerable groups such as aboriginal people, the poor and ethnic minorities.

    In Africa, the number of Covid-19 infections across the continent has exceeded 90,000 cases, with a total of 2,907 deaths. South Africa is the country most affected by the disease with more than 17,200 cases, of which 312 cases have died. The number of Covid-19 infections in Africa has been described as “stabilizing” in recent days.

  • Covid-19 caused infections of the intestines, kidneys and many other organs

    Pneumonia virus can spread throughout the body, to the lungs, throat, heart, liver, brain, kidneys and intestines.

    Published on May 13 in the journal Nature Medicine , a research team at the University of Hong Kong said the pneumonia virus can attack many different parts of the body.

    This finding helps explain why the symptoms of people infected with Covid-19 appear in many parts of the respiratory system. This includes blood clots that cause strokes in young people, blockage of the dialysis system, headaches and even kidney failure.

    Covid-19 is classified as a respiratory virus, spread through respiratory droplets, but it can still cause diarrhea and many other digestive symptoms. The researchers also found virus traces in the faeces of patients with Covid-19. This evidence shows that it can be transmitted through waste.

    Researcher Jie Zhou and colleagues at Hong Kong University tried to find out how the SARS-CoV-2 virus can thrive in the gut. In laboratory samples in both bats and humans, the virus invaded many internal organs. Viruses not only live but also grow exponentially.

    “The human intestinal tract may be the infectious route of SARS-CoV-2,” the research team said.

    Covid-19 caused infections of the intestines, kidneys and many other organs
    Covid-19 not only causes pneumonia but also invades and damages many other organs. 

    “A 68 year old female patient had a fever, sore throat, high cough and diarrhea after being admitted to the hospital at Princess Margaret Hospital. We isolated the infectious virus from her stool sample. Here we have demonstrated that the virus replicates in organic matter in the intestinal tract, ”Zhou said.

    In addition, another team at the University Medical Center Hamburg-Eppendorf (Germany) also performed autopsies of 27 patients who died of Covid-19. They found traces of the virus in many parts of the patient’s body.

    The pneumonia virus is mainly active in the kidney, which explains the rate of kidney damage is usually higher than other parts in Covid-19 patients.

    Infection with SARS-CoV-2 virus can make underlying diseases worse. Conversely, people with heart disease, diabetes and especially kidney disease will also be more vulnerable to the virus because of the lower ability of self-healing than healthy people.

  • Sweden has passed the deadly milestone with 1,000 coronavirus deaths

    Sweden has passed the deadly milestone with 1,000 corona virus deaths, far ahead of its neighbors.

    Officials say the peak could have come close, while scientists continue to question the government’s soft approach.

    101 people died of coronavirus in 1 million people

    The Swedish Public Health Agency (PHA) announced that the number of deaths for Covid-19 in the country was 1,203, as of April 15, or 101 deaths per million residents, compared to 51. in Denmark, 11 in Finland – two neighboring countries have imposed strict blockade early to contain the virus.

    The sign at a restaurant in Stockholm on March 26, the notice is still open and happy hours of the day. 

    The death rate per million people in Sweden is also significantly higher than the 37 recorded in Germany , and the number is equivalent to 79 deaths in the United States , but lower than the 182 deaths per million people in the UK and far less than 348 in Italy and 386 in Spain.

    Anders Wallensten, Sweden’s leading epidemiologist, said the number of new Covid-19 cases was beginning to decline and he was cautiously positive that Sweden had reached its peak. Meanwhile, government officials say the health system is coping with the situation.

    Public opinion polls continue to show people’s support for the government’s strategy, which urges citizens to take personal responsibility for complying with distance-holding guidelines rather than strictly enforcing them. strict rules required.

    While the authorities closed high schools and banned the gathering of more than 50 people, they also suggested – rather than giving orders, people avoid non-essential travel, working from home and in homes with people over 70 or feeling sick.

    The statistics show that about half of Swedish workers are working from home, the use of public transport has decreased by 50% in Stockholm while the streets in the capital have been less crowded by about 70%. with the usual. However, Swedes can still shop, eat and drink in restaurants, have their hair cut and send their children under 16 years old to school even if a family member is ill.

    Criticism rising

    The government refused to close primary and secondary schools – and the government’s insistence that only sick children should stay at home, made some families and teachers particularly worried.

    Healthy students whose parents are worried about not attending school have been threatened to report to social services, while families and school-related staff have written open letters expressing their dissatisfaction with government policy and believe that this risks the lives of children, relatives, and school staff.

    Swedish authorities have advised the public to keep social distance. 

    Swedish chief epidemiologist Anders Tegnell describes the Swedish approach as an attempt to ensure “to slow the spread and to keep the health services from being overloaded”. He thought it was important that a part of the population be immune.

    Mr Tegnell denied that he was seeking to establish a “rapid herd immunity” with the virus, a strategy initially used in Britain and the Netherlands before the soaring deaths caused these countries to change course.

    Some experts speculate that Sweden’s approach to managing the spread of the virus may also be affected by the local demographic situation – more than 50% of households are single – and confidential The population is relatively low at about 25 people per km2, compared with 205 in Italy.

    While the long-term impact is not yet known, Sweden’s strategy is not expected to help preserve its economic development this year, more than any other country taking measures. Swedish Finance Minister Magdalena Andersson said on April 15 that GDP could fall 10% this year and unemployment would rise to 13.5%.

    The strategy also faces stiff opposition from some of its own scientists. A team of 22 doctors, virologists and researchers on April 14 criticized the health authorities in an article published in the Dagens Nyheter newspaper.

    “There is a need to change completely and quickly the approach,” the expert group emphasized. “When the virus spreads, it must increase the social distance. Closed schools and restaurants. People who work with older people must wear full protective clothing. Isolate the whole family if one member is infected or tested positive.

    Mr. Tegnell dismissed criticism and argument over numbers. Previously, he had said that Sweden and its neighbors were in different positions on the curve, and that Sweden unfortunately had a large spread in care facilities for the elderly, which was not captured meet in other Nordic countries.

    The chief epidemiologist has repeatedly stressed that the world is still unclear about the coronavirus, he asserted that while Sweden could record more cases in the short term, it would not face the risk of infection. The infection increased greatly as many other countries removed the blockade.
