South America - Brazilian P1: Manus. Brazilian scientists prefer to speak of the P1 or 'Manaus variant'. (spread over 10 countries).
South America - Brazilian P2: Rio de Janeiro. The mutation P2 would have some similarities with the South African variant.
South Africa - B1351: Experts are concerned about the corona variants in South America, because the virus mutations show similarities with the South African variant. They may be more contagious and at least two vaccines appear to provide less protection than initially expected against the mutations. (spread over 41 countries).
UK - B117: This is an original and dominant virus type, according to several studies, deadlier variant. (spread over 80 countries).
California - Cal.20C: The California variant was first found in Los Angeles in a July 2020 test sample. It then took until October 2020 for the same virus variant to reappear in Southern California. Currently also in North California. (14-02-2020).
New York - B.1.526: mutation of this variant of the virus bears similarities to those from South Africa and Brazil, the scientists say.
Mexican - B.1.1.222: Mexican corona variant was found recently in Limburg (05-03-2021)
India - B.1617: Scientists are concerned about India, where a mutation of the virus seems to be circulating very quickly. Vaccines may be less effective against this variant. Indian doctors also notice that very young patients need to be ventilated this time. (20-04-2021)
The Delta B.1.617.2: was previously known as the “Indian variant”, as it was first found in India. It's one of three sub-lineages of the Indian variant, and is also known as B.1.617.2 (11-06-2021)
Omicron variant is B.1.1.529. The World Health Organization WHO has named the variant omicron, a reference to the Greek letter 'o'. Earlier variants were also named by the WHO after a letter from the Greek alphabet. Consider, for example, the beta and the delta variant. A "variant of concern" is slightly different from a so-called "variant of interest", as omicron was described. In the latter category, too little is known about the variant to really sound the alarm. Scientists are still investigating the variant. (29-11-2021)
IHU variant: The World Health Organization (WHO) has the so-called IHU variant of the coronavirus "on its radar" and is conducting research, a senior staff member said on Tuesday. The organization is not yet concerned. The IHU variant of the coronavirus, which was identified and provisionally named after the IHU Méditerranée Infection research center in France, was found in a vaccinated Frenchman in mid-November. This person had returned from Cameroon three days earlier. As far as is known, the IHU variant has been found in twelve people in southeastern France, including five children. IHU is not on the WHO's list of 'variants of care', nor is it classified under 'variations of interest' for the time being. (05-01-2022)
Local omikron variant: Chinese city of Tianjin tests all its 15 million inhabitants in one day.
The Chinese metropolis of Tianjin, which borders Beijing, is rapidly testing all residents for Covid-19. All nearly 15 million residents must remain indoors until health officials test them at home.
The operation must be completed within 24 hours. People who have been vaccinated less than 48 hours ago do not need to undergo a test.
The reason for the measure is the discovery of twenty corona infections in the city. According to the Chinese authorities, in at least two cases this concerns a 'local' omikron variant that does not resemble earlier, imported omikron variants. It is not clear where the two patients contracted the virus: they would not have traveled. (09-01-2022)
New dangerous mutation by 15 Feb. 2021 to June 2021
(Clinical Microbiologist, Subspecialty in Genetics and Infectious Microbes in Texas) A new dangerous mutation in the corona virus from February 2021 to June 2021 upcoming. Example from the points that have been seen: people who blink with eyes or get stutter. According to a new study you must create a high selenium protein in your body in combination with antioxidant intake and high doze vitamin C so that the virus tentacles can not stick in to your body parts.

Breakthrough at Ghent University: dogs's can smell coronavirus
Ghent University has trained six dogs that can be used to test whether people are infected with the corona virus, microbiologist Chris Callewaert told the radio program De Wereld Today of the Flemish channel VRT. The results the dogs get from smelling the virus are more accurate than those from a rapid test. In 95 percent of the cases, the dogs are able to trace the virus. The coast: €1
New variant of corona in New York B.1.526
Researchers are concerned about a new variant of the coronavirus spreading in New York, American media reports. Coronavirus variant B.1.526 first appeared in the city in November 2020. The researchers discovered the variant in the shared database GISAID. In February 2021, the mutated version appeared in a quarter of the sequences from the database that the scientists examined. The New York variant of the virus bears similarities to those from South Africa and Brazil, the scientists say. The variant is said to be more contagious and weaken the body's immune response. Scientists from the California Institute of Technology and a team from Columbia University researched the new variant in New York. They have not yet received any peer reviews. (25-02-2021)
7 virus variants found in the US with the same mutation
(NYTIMES) Scientists don't yet know if the mutation makes the variants more contagious, but they fear it could be the case. "There is clearly something going on with this mutation," said Jeremy Kamil, a virologist at Louisiana State University Health Sciences Center Shreveport and co-author of the new study. It's unclear whether it makes the variants more contagious. But because the mutation occurs in a gene that affects how the virus enters human cells, the scientists are highly suspicious. (17-02-2021)
Brazil is bracing for the 'Manaus variant' corona virus P1
The so-called 'Brazilian variant' of the coronavirus has already been detected in at least fifteen countries. But in Brazil itself, the mutation has not even been found in every state. Brazilian scientists prefer to speak of the P1 or 'Manaus variant', after the city where the mutation comes from. (14-02-2020)
South African variant distributed via Dubai
Two Brazilian variants and the South African variant of the coronavirus are also gaining a foothold in the Netherlands. The Outbreak Management Team (OMT) noted in the latest advice to the cabinet that the South African variant enters Europe via Dubai.
The OMT recommends that positive corona tests of travelers from the United Arab Emirates (which includes Dubai) be investigated on the South African variant. In addition, the germ surveillance (sample that looks at the corona variant) is further scaled up. Van den Hof calls it "not surprising" that the South African variant enters Europe via Dubai, since many intercontinental air travel goes via Dubai. She says not to worry. "No, that's a big word. We have to keep a close eye on it and it is good that through cooperation with other European countries those signals are coming in. It shows that it is even more important that people coming from Dubai are quarantined and get tested. We can't do more than that. " (10-02-2021)
A Brazilian corona variant with three worrisome mutations in the Netherlands P1 & P2
It was announced on Thursday 28-1-2021 that another corona variant from South America, with one worrying mutation, had been detected in Brabant. One Gelderlander also appears to carry this type of virus. The so-called P1 virus strain was found in Amsterdam, in two people who recently traveled to Brazil. The mutation was discovered during source and contact research. The virus variant is normally mainly detected around the remote Brazilian metropolis of Manaus.
It is not clear how many people have been in contact with the two travelers from the Amsterdam region. RIVM reports that further research is being carried out. The people in Brabant who came into contact with the other Brazilian corona variant, the so-called P2 virus strain, have not recently been to the South American country. The GGD is investigating how they contracted the virus.
Experts are concerned about the corona variants in South America, because the virus mutations show similarities with the South African variant. They may be more contagious and at least two vaccines appear to provide less protection than initially expected against the mutations. The vaccines are still considered effective.
The cabinet decided in mid-January on the advice of the experts to impose a flight ban to the continent, in order to prevent further spread of the mutations. The flight ban went into effect this week, but the corona variants were found earlier this month. (29-1-2021)
California, new variant of coronavirus Cal.20C
A new variant of the coronavirus CAL.20C has surfaced in California, the mutations of which are similar to the British and South African variant. The California variant was first found in Los Angeles in a July 2020 test sample. It then took until October for the same virus variant to reappear in Southern California. Currently also in North California. (27-1-2021)
Japan, new variant of coronavirus
Japanese authorities have found a new variant of the coronavirus in four people entering the country from Brazil. According to the Department of Health, the mutated virus partially resembles the British and South African variants. (12-1-2021)
Brazil, new variant of coronavirus P.1
Brazilian corona variant pops up in the Netherlands, in a care institution in Brabant (29-1-2021) This is a virus mutation that may be more contagious than the original coronavirus. A spokesperson for the institute confirms that it is not about the mutation that has gripped the Brazilian metropolis of Manaus. It would be a variant that was mainly seen in Rio de Janeiro. The mutation would have some similarities with the South African variant. The fear is that these variants will cause people to become infected with the corona virus a second time more often. Currently, more than one in three Dutch people who test positive would have become infected with the British corona variant, in February that share will probably increase to half. Experts from the OMT expect that the presence of virus mutations will increase the pressure on the health system again, resulting in more admissions and deaths. A third corona wave has been called "inevitable" before.
This mutation may be more contagious than other variants like the UK variant. (29-1-2021)

South Africa, new variant of coronavirus B1351
It seems that the so-called South African variant of the coronavirus (501Y.V2) can escape previously built-up defenses. This became clear on Monday evening during an extensive scientific briefing led by epidemiologist Salim Abdool Karim about the results of a month of intensive research into this variant. These are preliminary results that have not yet been published in scientific articles. Compared to the British variant, the South African has three changes in the portion of the spike protein on the outside of the virus that attaches to the human cell's ACE2 receptor. The two variants share one mutation that causes this: N501Y. But two others that the South African variant has, E484K and K417N, may enhance infectivity and immune system escape. (23-1-2021) (nrc.nl)
AstraZeneca vaccine less effective against South African virus'

UK, new variant of coronavirus B117
British Prime Minister Boris Johnson said at a press conference on Friday that there are indications that the mutation in his country may not only be more contagious, but also more deadly than the original coronavirus. But that is not yet certain, because much is still unclear. (23-1-2021)
The British variant much easier to transmit
This is an original and dominant virus type, according to several studies, deadlier variant, let's see why. The example comes from epidemiologist Adam Kucharski. As an example we first take the situation we are in now, with 9,000 infections per day and a reproduction rate of 1.15. This leads to each infected person infecting 1.15 people every six days. After a month we are at more than 18,000 infections per day. The percentage that dies from this is 0.8, or 145 deaths per day. But the virus now mutates into a version that is half deadly then this ensures that every infected person infected 1.65 others after six days. After a month, the number of infections has risen to 110,000 per day. With a death rate of 0.8, that means almost 900 deaths per day. Nearly 700 more than a virus that is half the deadly, of course this is just an example where all measures do not apply. But it shows that a more contagious virus is in theory a more deadly virus in the end.
The British corona mutation has been found in almost all EU member states, according to a meeting of the European Commission on Thursday. The South African variety has emerged in fourteen EU countries, and the Brazilian in seven. "We still have a major challenge ahead of us," warns chairman Ursula von der Leyen. (25-02-2021)

According to Pfizer and BioNTech, their vaccine also works when infected with the British or South African variant of the corona virus
"Small differences" found during research are unlikely to make the corona vaccine much less effective, the companies said in a statement Thursday. The companies emphasize that they continue to monitor how effective the corona vaccine is in practice. They promise to take action when needed. (28-1-2021)
Oxford, a vaccine against new variants
Scientists at Oxford University are hard at work developing new versions of the AstraZeneca vaccine that are effective against the corona variants from South Africa, Brazil and the United Kingdom, the British newspaper Daily Telegraph reports. (21-1-2021)
AstraZeneca will deliver fewer vaccines than expected in the first quarter. This is because a European production has been send to UK. The European Commission informed AstraZeneca on Monday 25-1 that it expects the contractually agreed amount of doses to be expected as soon as possible. Governments want to know what they can count on. This is necessary in order, for example, to be able to decide whether they should keep doses on hand to be able to administer the necessary second injection to vaccinated people. (27-1-2021)
Amsterdam UMC started a major investigation into a new corona vaccine. Hospitals around the world are participating in the study, which requires a total of 36 thousand participants.

The breast milk of women who have become infected with the coronavirus contains important antibodies against the coronavirus. The discovery was made by researchers from the Emma Children's Hospital of Amsterdam UMC. The antibodies in breast milk were also still present after the milk was heated, the researchers report in a press release. According to the researchers, this is important, because only after heating (pasteurization) the breast milk is usable for others. (18-08-2020)

Corona is even more harmful than we already knew: it also affects the brain
Dutch researchers at the Amsterdam UMC have discovered that corona is even more harmful than we already knew: it also affects the brain. The disease can cause the immune system in the brain to run wild. The research is published today in the leading medical journal The Lancet Microbe. Immune cells (so-called T lymphocytes) were discovered that do not belong in the brain. They found these abnormalities in the entire brain and spinal cord in the deceased patients. "These are cells that are normally excluded from the brain," says dr. Van der Valk. "But in the covid-19 patients, we saw that they had left the bloodstream and entered the brain tissue. Then I know as a pathologist: here's something not ok. (26-09-2020)
Vaccination, the Dutch population is divided into groups
The pace of vaccination will slow down because pharmaceutical AstraZeneca can deliver fewer doses of the corona vaccine in the first quarter than agreed. That is what Minister Hugo de Jonge (Public Health) says on Monday 25-1 about the Dutch vaccination strategy. Change of plan: Vaccination strategy (version January 12, 2021)
