Now that more than 70% of the Spanish population is vaccinated, we look back at reinfections with caution. We know that they are possible; but they are very rare cases. In fact, we did not begin to see people with COVID-19 reinfection until almost a year after the pandemic began. That does not mean that they are occurring and that you have to be careful; as well as we have to prevent infections despite having the complete guidelines for the coronavirus vaccine. But what exactly is happening with reinfections by the coronavirus in Spain?
In recent months we have seen many more infections, despite the SARS-CoV-2 vaccines; but also many fewer deaths, also thanks to the injections. Because the virus has been spreading more, with different variants, that implies that reinfections have been occurring of COVID-19. Some of these reinfections are confirmed; others fall into the categories of “possible” or “probable”, as explained from eldiario.es.
Only 8% of the cases classified as COVID-19 reinfections know that they are without any doubt
But let’s look at the data. Between May and September of this year there have been 1,300,000 cases of COVID-19. Of them there is only 9,082 cases that may be reinfections of COVID-19. Some, as we said, are confirmed: 729 of these patients have a confirmed diagnosis of reinfection by this coronavirus. That is, only 8% of the cases classified as reinfections know that they are without any doubt. On the other hand, 77.3% of the cases are “probable” compared to only 14.7% of the “possible” ones. However, we continue to talk about a process that, at the moment, is less than 1% of diagnosed cases. So that we shouldn’t be worried; Although we do take preventive measures even if we have previously passed COVID-19.
How to know if it is a reinfection of COVID-19?
To know whether or not they are reinfections of COVID-19, several factors must be taken into account. The first, that the person has recovered from COVID-19 and, after this, has returned to be sick with the virus. From what is being seen, the new reinfections are before different variants of the coronavirus (not to be confused with strains, since they are not the same). That is, a person who has already passed the alpha variant, for example, would be difficult to present symptoms again when coming into contact with the same variant; but you could get sick if you catch the delta. Even have symptoms. It is also being seen that reinfected people, in general, pass COVID-19 a second time asymptomatically or with very mild symptoms.
But knowing if there is reinfection of COVID-19 is not easy. Keep in mind that many people fell ill at the beginning of the pandemic; when no diagnostic tests were done yet. That is why it is difficult to know exactly how many real reinfections there are. However, with the data we have in hand, yes we know that they are less than 1% of the cases. Therefore, if a variant does not appear that causes more reinfections of COVID-19, for the moment we can be calm.
