of Covid-19 c "is also the closure of gyms and swimming pools. In fact, since the beginning of the health emergency, sports centers and facilities have been considered places with a high risk of contagion. For this reason, during the lockdown before and in the areas red and orange then, the various decrees have prohibited its use by users. These structures were able to reopen to the public only in the short periods of easing of containment measures, but respecting strict regulations. Now, however, a window is open. At least for the aquatic centers. According to the new English study, not yet subjected to revision, in fact, the chlorine in swimming pools would not only be very effective in deactivating the Coronavirus, but it would also be extremely fast: it would act, in fact, within 30 seconds. If this hypothesis were confirmed, therefore, the combination of Covid chlorine in swimming pools and reopening of the plants, perhaps it would be possible.
-CoV-2 with chlorinated water. The aim was to study the impact of different concentrations of chlorine diluted in water on the novel Coronavirus in view of the reopening of swimming pools in the UK (which should take place shortly). The results were very positive and seem to confirm that Covid and swimming pool chlorine "do not" agree. In fact, according to the analyzes conducted, it seems that a chlorine concentration of 1.5 milligrams per liter and an acidity index between 7 and 7.2 are able to reduce the infectivity of the virus by more than a thousand times in just 30 seconds. The low degree of infectivity and the dilution of the microorganism would suggest that the risk of contracting Covid-19 in the pool would be very low.
For a "further confirmation, the experts used different concentrations of chlorine and pH levels to evaluate different scenarios. They thus obtained a new confirmation of the" effectiveness of swimming pool chlorine on the contagion and spread of Covid-19: a concentration of free chlorine. of 1.5 milligrams per liter and a pH level of 7.0, which are the values suggested by the guidelines for the operation of swimming pools, according to their calculations would be sufficient to make the possibility of contagion negligible.
has a protective role against the disease. On the website of the "Istituto Superiore di Sanità, for example, the following is reported."There is no evidence that COVID-19 can be spread to humans through the use of swimming pools, hot tubs. The correct operation, maintenance and adequate disinfection (for example with chlorine and bromine) of swimming pools and whirlpools ensure the inactivation of the virus that causes COVID-19. By the COVID-19 Communication Group of the ISS (source: CDC ) ".
Now this study seems to give further confirmation to these theses. "We performed these experiments in our high containment laboratories in London so we were able to measure the virus' infectivity and its ability to attack cells," explained Wendy Barclay, of Imperial College London.
The first reactions are very positive.
"These results - explained Jane Nickerson, managing director of Swim England - support the hypothesis that swimming pools are safe environments if appropriate measures are taken. This is fantastic news for operators, our members and clubs who participate in sporting activities, swimmers and those who rely on "water to stay physically active".
"We are thrilled with these results - adds Paul Thompson, founder of Water Babies - as we prepare to restart classes and welcome children and clients back into the country's indoor pools. We know that swimming has multiple benefits for both physical and mental health. for children and adults of all ages "and we can't wait to resume activities".
