Covid-19: Some reasons why you haven't caught the virus

Perhaps you are among those who have never caught Covid. While this may be partly due to luck, there are other factors to be taken into account, according to the findings of several studies.

Covid numbers are soaring, warnings are pouring in on TV and loved ones are panicking about getting together for the holidays. And while some colleagues are slowly recovering from the Covid tornado, you're thankful for life, as you've always managed to slip through the cracks since the pandemic began. Like many, you have probably wondered why you escaped. Scientists have looked into this question and tried to answer it.

You don't have children

Unsurprisingly, Covid infections are strongly linked to the places you frequent. If you are not a big party goer, you are less likely to contract the disease because bars and clubs are the best places to transmit Covid. On the other hand, according to the Comcor study, conducted by the Pasteur Institute, 'no excess risk has been documented for cultural venues, shops (excluding convenience stores), restaurants (at a time when many operated outdoors and with ventilation), places of worship, sports activities and family gatherings (excluding weddings, for which an excess risk has been documented).'

Scientists also correlated Covid infections with the presence of children in the family home. So, if you don't have any offspring, this may partly explain why, because in the over-40s, 'an increase in infection' of 30% for schoolchildren and 90% for very young children (under three years old) has been observed.

Your blood type protects you

Working from home also has a role to play. The generalisation of this phenomenon has probably enabled thousands of people to escape the disease. It could reduce the risk of transmission by 24% to 30% depending on the conditions. Since Boris Johnson has reinstated 'Plan B,' the return of the order to work from home has been generalised.

Finally, if you are lucky enough to be of blood group O, you would be less likely to contract the disease but also to develop severe forms. Your genes would also allow you to avoid it.

A decryption published on 4 October on the CEA website says:

Recently, genetic analysis of the genomes of people affected by Covid-19 revealed the existence of a possible genetic predisposition.

On the other hand, all these elements, highlighted by scientists, do not dispense with barrier measures. Caution is still required.
