People infected with Omicron do NOT clear the virus quicker

People infected with Omicron do NOT stop being infectious sooner than they did with past variants, scientist claims

  • Dutch virologist says she is ‘not convincedOmicron infectious period is shorter
  • Countries shortening isolation period are doing so because variant is less severe
  • Studies suggest Omicron is shed from 2 days before to 7 days after symptoms
  • People infected with 오미크론 do not clear the virus quicker than those who had earlier strains, a scientist has claimed.

    Many scientists believe that part of what makes Omicron so transmissible is how quickly someone becomes infectious after catching it.

    That theory, which also assumes people shake the variant more quickly, has seen most countries reduce or entirely scrap the seven-day isolation period for positive cases.

    But Dr Marjolein Irwin-Knoester, a virologist from the University of Groningen in the 네덜란드, said she is ‘not convincedby the data to support the assumption.

    She pointed to a number of lab studies which still suggest Omicron carriers are infectious two days before symptoms start to seven days after onset — in line with other strains.

    Dr Irwin-Knoester will tell a medical conference in Lisbon tomorrow that a new variant could throw everything ‘up in the airagain if nations stick to their reduced quarantine times.

    She did, 하나, admit that Omicron’s reduced severity made it ‘acceptable’ 순간에.

    Studies have so far suggested a person who catches Omicron can pass the virus on to others from around two days before symptoms start to seven days after onset — in line with other strains. Data from Oxford University researchers (shown in graph) suggests almost all transmission occurs shortly before and after symptom onset

    Her comments come a month after the legal requirement for infected people to isolate in England was scrapped. It has also been switched from law to guidance in Northern Ireland.

    Organ donation from people who died with Covid is ‘safe’, 과학자들은 말한다

    Organs of people who died with Covid are safe to give to transplant patients who have been vaccinated or previously infected, 과학자들은 말한다.

    Organ replacement surgery ‘fell significantlyworldwide when the pandemic hit, with kidney, lung and liver transplants the worst affected.

    영국에서, transplant operations fell by 20 per cent in the first year of the pandemic.

    But Professor Paolo Grossi, an infectious disease expert from the University of Insubria in Varese, 이탈리아, said ‘evidence is continuing to buildthat organ donation from people who have previously been infected is ‘safe’.

    And even organs from donors with an ‘active Covid infection can be consideredif their infection was asymptomatic and the virus was not the cause of their death.

    Professor Grossi is tomorrow set to tell the European Congress of Clinical Microbiology and Infectious Diseases, 말했다: ‘Based on growing worldwide experience, we believe that organs from donors with past or active SARS-CoV-2 infection may be safely offered to candidates with immunity against SARS-CoV-2 because of previous infection or vaccination.

    ‘This might contribute to increase the donor pool.

    He also pointed to 10 liver transplant recipients in Italy, two of whom had Covid infections, while eight previously had the virus.

    One of those infected subsequently died from a bacterial infection following the transplant, but the other nine patients survived.

    하나, people are still required to isolate for at least one week in Scotland and six days in Wales.

    영국 이외의 지역, isolation duration periods vary from four days in Norway to 10 days in Germany.

    Dr Irwin-Knoester said a seven-day isolation period ‘should be safein almost all cases, but five days ‘strikes an acceptable balancebetween the infectiousness of the virus and the desire to get back to normal.

    Dr Irwin-Knoester is tomorrow expected to tell the European Congress of Clinical Microbiology & Infectious Diseases: ‘The decisions being made by different countries around the world to shorten the period of isolation for Omicron infections are partly based on evidence from modelling.

    And she noted the move also takes account ‘of the fact that Omicron is causing less severe disease, and fewer hospitalisations and deaths’.

    그녀가 말했다: ‘It is a way of returning to something like normal life and accept transmission of this less dangerous Omicron variant.

    ‘From the evidence so far, I am not convinced that a person is likely to be infectious for a shorter period of time with Omicron as they would have been with previous variants.

    Dr Irwin-Knoester said a maximum of seven days isolation ‘should be safe in almost all cases of infection’.

    But a five-day isolation period ‘strikes an acceptable balance between the infectiousness of the virus and what most communities are willing to accept going forward, especially after around two years of restrictions in many cases’, 그녀는 덧붙였다.

    하나, Dr Irwin-Knoester noted that people still suffering from respiratory symptoms, such as coughing and sneezing, after seven days should continue to isolate for 10 ...에 14 일.

    And those severely unwell with the virus often ‘shed for longer’, while immunocompromised people can transmit the virus for months.

    Dr Irwin-Knoester also warned that a new variant ‘could throw everything up in the air’, especially if it causes more serious illness or escapes the protection offered by Covid vaccines.

    ‘If it is a new variant that makes us seriously ill, I would recommend returning to longer periods of isolation – with seven days as a minimum,’ 그녀는 덧붙였다.

    영국에서, the legal requirement to self-isolate after testing positive came to an end on February 24, although people are still advised to do so.

    The requirement to wear face masks also came to an end on that date, while free tests are being scrapped from April 1.
