Viruses in public transport toilets!

Updated: Dec 4, 2020

Toileting is a basic human activity. Human beings have to urinate and defecate as a regular daily activity to maintain a normal physiological life. During travel, urination and defecation are required. During long travel, the toilet in the vehicle is also an important issue.

We do not pay due attention to this

Toilets are seen in several types of vehicles, such as the bus and the airplane. They are considered as public toilets, and concerns about them usually concern sanitation. Disease transmission can occur due to a dirty toilet in a travel vehicle.

On Airplanes

Toilets in airplanes require a special design for the prevention of spillage. Microbial contamination occurs in airplane toilets and might be a source of infectious disease transmission. On many airlines, technical operations employees disinfect the lavatories overnight using cleaning products containing bleach (or sodium hypochlorite).

Between flights during the day, the cleaning crews empty the trash, restock supplies, and mop the lavatory floor. In flight, the flight attendants usually check the lavatories regularly, typically every 30 minutes, partly to make sure that paper products are still available but more to make sure that no one is hiding out indefinitely in the lavatory.

On Trains and Buses

On a train, the toilet sanitation must be controlled. The design of a train toilet is also important. It must be a good design with a coat or luggage hook which is suggested to be located about 1.8 meter above the floor. Contamination due to droplets from train toilets is possible and can be detected at high levels at the end of a train. Preventing contamination becomes an interesting issue.

Similar problems are also observed in a bus toilet. Intestinal parasitic contamination is detectable in buses with toilets.

On Cruise Ships

Finally, a similar problem has also been reported for toilets on cruise ships. To provide good toilet facilities is mentioned as a way to prevent the problem of food-borne infectious diseases relating to cruise trips. Regular cleaning of the toilets is needed. In a recent study, only one-third of cruise ship toilets received proper daily cleanings.

The issue of toilets in transportation vehicles is an important but forgotten issue. Usually, no one specific person is assigned to deal with this public health issue.

All public transport toilets have one problem in common: People bring a lot of bacteria into toilets, the researchers found. Within an hour of normal use, there were 500,000 bacterial cells per square inch on the bathroom surfaces, on average. It's a tiny compartment containing a toilet that flushes with violent force. Fecal bacteria spread throughout the lavatory compartment in the mist caused by flushing. Studies find dangerous E. coli bacteria on and around the water taps.

We have created a solution

For these reasons, we at COCOON GROUP have created a separate brand, AirDNA, that tackles these issues. The solution we create will be adaptable not only in public transport, but also in all households, hotels and other public places.
