If you have recently contracted COVID-19 and thought that you were resistant for a few months – you may have to call up again . Researchers have find that the shortest - known COVID reinfection point is 20 days .
Thefindingswere showcased in a display at the European Congress of Clinical Microbiology and Infectious Diseases ( ECCMID ) in Lisbon , Portugal ( 23 - 26 April ) .
The unlucky somebody who contracted the computer virus was a 31 - yr - sure-enough health care doer . It is reported that the woman did not develop any symptoms after the first positive PCR psychometric test on December 20 , 2021 , and after a 10 - 24-hour interval self - isolation period returned to body of work . However , she developed a cough and fever three weeks later and so took another test , and this too was positive .
Whole genome sequencing discovered that the woman was infected with two unlike variant – Delta in December andOmicronin January . The fair sex was fully inoculate and had incur a booster shot shoot 12 24-hour interval before her first incontrovertible exam .
“ This causa highlight the potential of the Omicron variant to bilk the previous immunity acquire either from a rude infection with other variants or from vaccines . ” Dr Gemma Recio , one of the studies authors from the Institut Català de la Salut in Tarragona , said in astatement . " In other words , people who have had Covid-19 can not seize they are protected against reinfection , even if they have been full vaccinate .
" Nevertheless , both previous infection with other stochastic variable and inoculation do seem to part protect against hard disease and hospital care in those with Omicron . "
In the UK and US , it is no longer a requirement to take a confirmatory PCR test after a positivelateral flow test(LFD ) . Therefore , it is very difficult to set the accurate number of reinfection cases , as this demand whole genome sequencing to differentiate between dissimilar stock .
presently , the virus is still classed as a pandemic – the World Health Organization ( WHO ) define diseases as this when it has spread worldwide , and is unpredictably increasing in numbers . However , this disease is slow heading towards becoming anendemic – which is similar to the common cold or influenza , where case numbers game are still big but at a more predictable charge per unit . If coronavirus becomes aseasonal virus , scientists envision that everyone will eventually catch COVID-19 twice , and probably many more times over the form of their lifetimes .
Despite this , COVID-19 variant monitoring is still very important even in masses who are fully immunize , as this inquiry will aid pinpoint variants that can evade vaccinum and the full effects of long COVID are still not known .
