Every day, buses travel through the streets of the city, carrying countless passengers to their respective destinations. In recent times, some buses have been equipped with anti-bacterial lifts and chairs, which would have been a welcome step towards improving public health, but many have mistakenly assumed that these anti-bacterial facilities would have prevented the spread of the disease, far from it.
The emergence of antibacterial stretchers and chairs does create a “front line of defence” for antibacteria. These facilities often use special materials and techniques, some of which are integrated with nanosilver ion, which, by virtue of its super-oxidative properties, is able to strike precisely against the cytowalls, membranes of bacteria, disrupt the metabolic process of bacteria, and make it difficult for common pathogens, such as coliform and yellow raisins, to survive and reproduce in the arm. The use of anti-bacterial-treated leather or fabrics can also inhibit the growth of disease, reduce the vulnerability of passengers to infection through direct contact and, to some extent, create a relatively clean travel environment for passengers.
But this appears to be a strong anti-bacterial barrier, and there are holes in it that simply cannot block the path to disease transmission. First, the bus is a highly populated and mobile “mixer”. At each station, new passengers boarded the car, carrying their “micro-organism cysts”, dust on their clothing, the mud on the soles of their shoes, and the various strains encountered in public places. Even when the arm and seat are anti-bacterium, these bacteria from all sides can readily be exposed to passengers’ clothing, place their belongings, etc., and other areas within the vehicle contaminated, such as car windows, zipping rings, moneyboxes, etc., still have numerous opportunities for “floating crime”.
Second, the means of transmission of the bacteria are complex and do not depend solely on exposure. In small, enclosed cars, the air flows poorly, as long as one passenger coughs and sneezes, and the foams of pathogenic microorganisms such as influenza viruses and gland viruses spread out in an instant, and other passengers, even if they hold their antibacterial arm and sit firmly in their antibacterial seats, are exposed to the risk of inhalation through the air. Moreover, air-conditioning in summer cars, if the air vents are not cleaned in time, and the growth of fungus spores spread with the cold wind, also threatens the health of the passengers, which is too long for antibacterial hand and seat whips.
Third, the efficacy of antibacterial products is not consistent. With daily high-intensity bus operations, antibacterists and seats are subjected to frequent natural wear and tear, such as friction, squeeze, and sun and rain, the antibacterial coatings on their surfaces will gradually wear and tear down, the antibacterial ingredients will be lost and the original antibacterial capacity will be significantly reduced. The anti-bacterial facilities of a bus that has been in service for many years may have been defunct, but the passengers are often hard to detect and are still blindly dependent on its protection.
To effectively break the transmission chain of the disease on the bus, there is a need for a comprehensive and multi-pronged approach. Public transport companies, on the one hand, should not simply be content with the installation of anti-bacterists and chairs, but should strengthen the daily cleaning of vehicles by regularly cleaning at depths in every corner of the vehicle, including the floor, roof and window cracks, where there is a high risk of contamination; increasing the frequency of ventilation, using new wind systems or open windows, to allow fresh air to circulate in the car and to dilute the bacterial concentrations; and, on the same day, in the high-prevalence season, general disinfection of the vehicle and the failure to multiply the disease.
For passengers, their own awareness of protection is also crucial. The use of a mask on a car is both a barrier to the spread of a flurry and a degree of isolation from exposure to contaminated bacteria; it minimizes the use of the hand to touch the mouth and nose and reduces the opportunity for the disease to enter the body; it washes its hands, washes its hands first after getting out of the car, removes the potentially contaminated bacteria and insures itself and others ‘ health.
The installation of anti-bacterial hand and seating on buses is a commendable advance, but it is only a small step to truly stop the spread of the disease. Only a public transport operator working hand in hand with the passengers to complete the short-walled and enhanced protection will make the bus carriage a safe port, rather than a “hotbed” of disease. Don’t be confused by seemingly powerful antibacterial symptoms that defend each and every car’s health.
