Wuhan Virus Swimming Pool

Wuhan Virus Swimming

This post is all about whether the Wuhan coronavirus can spread in swimming pools. It is a top search in Google, however there is currently zero information about it.

We will list down various sources on other types of similar flu viruses and whether it can spread through swimming pools.

Source 1: Poolman.com (Yes!)

The short answer is yes. As Every Day Health summarized, germs that cause the flu and other illnesses spread so fast because people transmit it by simple motions, like a sneeze or a cough. Everyone from children to coworkers to spouses can be culprits. If any of them uses the pool, it can easily get to you.

No research has been completed on the susceptibility of H1N1 influenza virus to chlorine and other disinfectants used in swimming pools, spas, water parks, interactive fountains and other treated recreational venues. However, recent studies have demonstrated that free chlorine levels recommended by CDC (1–3 parts per million [ppm or mg/L] for pools and 2–5 ppm for spas) are adequate to disinfect avian influenza A (H5N1) virus. It is likely that other influenza viruses such as H1N1 virus would also be similarly disinfected by chlorine.

Source 3 (Channel News Asia):

Q: Can the virus be spread through water such as via swimming pools? Or through one’s eyes?

Prof Gray: We don’t know, but other respiratory viruses can, such as adenovirus which is a hardier type of virus.

Prof Wang: Transmission through the swimming pool is unlikely unless the person is swimming very close to an infected person. Yes, it is possible to be infected through the eyes.

Asst Prof Anderson: It is unlikely that the coronavirus can be spread through water, especially chlorinated swimming pools. Coronaviruses are also not known to be spread though the eyes.

There is an anecdotal case of infection through the eye and, if this infection did occur, it is an extremely rare event.

It is basic chemical knowledge that chlorine in pools is a powerful disinfectant. At high concentrations, chlorine is capable of destroying any living thing, not just Wuhan virus. However, swimming is not 100% underwater, there is a period of walking into the swimming pool, as well as breathing above water. During those periods above water, it is possible for the Wuhan virus to be transmitted. Also, if the chlorine concentration is not strong enough, it may not be enough to disinfect the virus.

Hence, it is better to be safe and avoid swimming pools during this period!


Congratulations to Joseph Schooling for Gold!

Heartiest congratulations to Mr Joseph Schooling, who has achieved the legendary accomplishment of a Gold medal at the Olympics! Good job!

Here is some analysis of factors contributing to Joseph’s Schooling’s success:


Joseph’s height is 1.84 m (close to the ideal height of 1.90 m). In swimming, a tall height is desirable, as that would lead to an instant lead the moment you jump into the water. But this is not basketball, too tall (e.g. over 2 m) is probably not good as that will lead to increased drag and bad aquadynamics. So judging by height of former Olympic swimmers, roughly 1.90 m is the ideal height.

In fact, in 2006, “Schooling’s parents, Colin and May, send him for a bone test – which calculates growth potential – to see how far he can go in the sport. The test reveals that he will hit 1.90 metres, which is an optimum height to excel in the sport at the highest levels.” (http://www.todayonline.com/sports/schooling-story)

Motivation / Training Hard

This is probably the most important factor. Even when just eight years old, Joseph Schooling woke up his dad at 4.30 am to request to go for swimming training.

Schooling also took training to the highest level by going overseas (to Texas) for his training.

Joseph Schooling also has a motivational poster (see below) to remind himself daily of the times he need to achieve for a podium finish.

Supportive Parents (and relatives)

Joseph Schooling’s grand-uncle Lloyd Valberg, a former high jumper, was Singapore’s first ever Olympian at the 1948 London Games. He was the one who inspired Joseph to aim for the Olympics, when Joseph was just 6 years old.

“Colin (Joseph’s father) and his wife, May, decided to groom their only son to the best of their ability, going so far as to ensure he had access to swimming facilities to train during every vacation they took during his childhood. This would continue into his formative years, when Joseph was sent first to the famed Bolles School in United States to train under renowned coach Sergio Lopez and now the University of Texas to continue his development at the best possible environment.” (from https://sg.sports.yahoo.com/news/colin-schooling–the-world-has-taken-notice-of-joseph-and-singapore-150934197.html)

Bounceback from Adversity

In 2012 Olympics, Joseph met with extreme bad luck in the form of his goggles and swim suit not being approved, leading to a last minute change which would affect his timings.

Despite that, Joseph continued to persevere in his training, which led to his fantastic results in 2016.

Excellent Coach

Joseph Schooling’s coach is Sergio Lopez, “who is a former international top swimmer from Spain, who won the bronze medal in the 200 meters breaststroke at the 1988 Summer Olympics in Seoul” (Wikipedia).

Coach is very important, Michael Phelps credits his success to his legendary coach Bob Bowman, who has written a book The Golden Rules: 10 Steps to World-Class Excellence in Your Life and Work.

Government Support

The Singapore government has humanely allowed a deferment from National Service (2 year mandatory conscription into the army) for Joseph Schooling. This is a crucial factor as for Olympic athletes, uninterrupted training is of utmost importance.
