November-March is the time of colds and viral infections. During these months, millions of people fall ill. Huge amounts of money are spent on treatment, hundreds of thousands and thousands of working hours disappear. The most annoying thing is that people themselves are to blame for these epidemics! After all, most viral infections are transmitted only by airborne droplets! And people coughing and sneezing at work, in transport, in public places infect each other. And patients with asthma, bronchitis and other lung diseases are at the greatest risk. But avoiding infection in a modern city is quite simple: 1) try to avoid contact with people who carry respiratory infections. If someone comes to work sick, the whole team try to send him home to be treated. If he does not fulfill his obligation to be treated at home, explain that this is tantamount to causing deliberate harm to everyone; 2) if someone at home gets sick, try to isolate the sick person, put on a gauze mask when you are near him (this is easier than putting on masks for all healthy family members); be sure to ventilate and “ quartz ” the apartment with an ultraviolet lamp; 3) if “sniffing” children appeared in the class where your child is studying, “keep” him at home for a week – missed classes will more than pay off if he does not get sick, like everyone else; 4) teach him the rules of “flu safety” and follow them yourself: never allow others to cough in your face, do not allow a subject who does not cover his mouth and nose with a handkerchief to sneeze and cough in his direction. Move away from him or turn your back on him. And if this is not possible (for example, in public transport), cover your mouth and nose with a handkerchief yourself or unfold a newspaper in front of you. If possible, move or change seats – I assure you: standing on your feet is less harmful than a respiratory infection; 5) but, most importantly, do it discreetly and as delicately as possible. Do not enter into conflict with people who are coughing and sneezing and do not try to educate strangers. Unfortunately, many representatives of our society are not only uncultured, but also aggressive. Remember: your caution will be rewarded and you will not get sick! But what if, despite the precautions taken, no luck? Take immediate action to prevent a viral infection from causing a severe asthma flare-up.
