Coronavirus – Is it Safe to Use Your Home Swimming Pool?

With spring here, and so many of us isolating at home amid the Coronavirus lockdown many people will be looking to open their swimming pools for a source of relaxation, exercise and enjoyment.

But is it safe to share your home swimming pool?  Does chlorine, bromine etc.. kill Coronavirus / Covid 19?

According to CDC (Centers for Disease Control and Prevention):

“There is no evidence that COVID-19 can be spread to humans through the use of pools and hot tubs. Proper operation, maintenance, and disinfection (e.g., with chlorine and bromine) of pools and hot tubs should remove or inactivate the virus that causes COVID-19.”

Of course, you should still consider keeping distance between one another if you can, around 6ft.  It’s also not a bad idea to shower before you get in the swimming pool to keep the pool as sanitized as possible and give the chemicals the best chance to do their job.

CDC officials say this coronavirus is thought to spread mainly from person-to-person. It spreads between people who are in close contact (within about 6 feet) with one another and through respiratory droplets produced when an infected person coughs or sneezes, according to the CDC.

Those who are unwell or suspect they may have Coronavirus should refrain from swimming if others are to use the same pool.

As always you should check your pool chemicals regularly to ensure that your swimming pool remains healthy.
