COVID-19 Can Rarely Reinfect Again

Health Editor’s Note: So you have already had COVID-19 (positive testing) and now you have symptoms again, possibly worse than the first time. Yes, you could have another COVID-19 infection but it will not be exactly like the first one that you have recovered from. Typically new mutations occur in COVID-19 every 15 days and that would be a natural change that happens to any coronavirus and this change will alter the potency of the coronavirus, not make it a new strain. So the second infection will be slightly different than the first one, but not a reinfection but nonetheless, an infection caught from another source than the first one. Mutations can be analyzed since they involved in the genetic signature of the coronavirus.
There were four seasonal coronaviruses prior to the introduction of COVID-19 and reinfections can occur in those as quickly as 6 to 9 months after infection. Since we have been exposed to these seasonal coronaviruses before (COVID-19 is a novel (new) coronavirus) we have adapted to them. Also, some people do not develop an adequate antibody response after the first infection. The immune system did not function to its full capacity, thus a ‘reinfection’ from the slightly altered coronavirus.
Bottom line, continue to wear masks while in public places, physically distance yourselves from those you do not live with, do not touch your face, mouth, nose, or eyes without first thoroughly washing your hands, wash you hands all time, stay away from groups, stay away from those who are ill, stay home if you are sick, even if you think or know that you have already had COVID-19. The COVID-19 vaccine is the definitive prevention of future bouts with COVID-19 and the initial two doses may need to be boosted yearly, exactly like the current influenza vaccines…..Carol
