BRATISLAVA, July 9 (WebNoviny.sk) – The public health service, as part of the summer tourist season, advises on which bathing and watering areas it is possible to swim and warns against cyanobacteria present in the water. The safest is to swim in officially managed pools and in water areas, the quality of which is monitored by public health authorities.
The quality of bathing water can be revealed to the naked eye, if the water feels or is repulsive, people should not bathe there. From a health point of view, it is not safe to swim in natural aquatic areas where waterfowl are caught because they can also transmit certain pathogens, such as salmonella.
Signs of occurrence in swimming pools
Consider swimming in the waters near which dead animals or sewage effluent have spilled. In the case of public pools, it is important to note the damage or the viscous deposits on the walls and tiles – if the pools are in such a state, hygienists do not want to swim in them.
"The bath is for healthy people who have normal immunity and intact skin that, if damaged, can be a route of entry to the infection", said the chief hygienist of SR Ján Mikas. it is possible to completely exclude contact with various types of waterborne micro-organisms, but the problem arises if they are overpopulated disproportionately.
[4] "These are micro-organisms that are a natural component of the environment and in some quantities are also part of the phytoplankton of all reservoirs and lakes." Sinice can cause respiratory problems in children, fringes of the skin or ocular conjunctivitis.After swallowing more, they can also cause intestinal problems, seizures and nausea.Although not all cyanobacteria produce toxic and allergic substances, the risk increases with the length of stay in the water and baths repeated for several days. " warns against hygiene.
Reproduced and accumulated toxic cyanobacteria form flakes or noises from colonies that are dispersed in a column of water or accumulated on the surface of the water. They live mostly in green or blue-green, they can be caught on the banks. Increased presence of cyanobacteria, especially after prolonged sun and warm weather. Mikas pointed out that the proliferation of sinuses represents a greater health risk than the reproduction of algae.
"That water contains cyanobacteria, it can be tested in a simple way: the water must be taken from the translucent container and left in the light for 15 to 20 minutes. colored ring resembling a cut pin or a green semolina forms on the water and that the water remains clear, it is probably a cyanobacteria. If the microorganisms remain dispersed in the water column, they are healthy and insignificant algae ", indicates in a press release .
Beware of pools
As for swimming, visitors should also check the color of water and odors before entering the pool. They should also take a shower before entering the pool. A full shower can reduce the risk of water contamination up to ten times. People with communicable diseases should not enter the pool.
"Visitors who often do not comply with the regulations of the operator, the rules of hygiene or visiting swimming pools with communicable diseases, also have a lot of poor quality of life. water " informs Mikas.
He adds that the water in the pools is usually warmer, so "better" is given to bacteria, viruses and parasites. The water in the public pools is the cause the most common intestinal diseases, including viral diseases such as eye inflammation viral hepatitis A.
Can be infected with parasitic worms (human rubella, baby butterflies), the thermal water basins may contain protozoa – amoebae, some of which are dangerous to humans and cause inflammation of the brain and cerebral mucus.
Children and adults are also exposed to microscopic fungi, molds and yeasts on artificial pools. On the other hand, the excessive use of chlorine, which belongs to the most used disinfection, may be sensitive to children, especially predispositions to allergies. Although the decree limits the amount of chlorine in the water, in practice, hygiene encounters cross the border.
The ILO also draws attention to other principles of bathing. Children should not be left unattended, after each bath, people should be able to take a shower and dry themselves, they should not go to an unknown water, they should avoid overestimating their abilities and not jump into the water. ;water. where it is forbidden.
