How to prevent respiratory infections?

When winter and spring meet, it is not too cold but still not warm, and it is easy for people to get sick. The human respiratory tract is divided into the upper respiratory tract and the lower respiratory tract, which means there are two respiratory tract infections. Respiratory tract infections can be well prevented as long as sufficient preparations are made. So, how to prevent respiratory tract infections? Let’s take a look now, I hope it will be helpful to you.

Acute upper respiratory tract infection can occur throughout the year. Typical cases start with sudden chills, followed by high fever, with body temperature as high as 39℃~40℃, presenting a prolonged fever type, often accompanied by headache, muscle aches all over the body, and decreased appetite. Dyspnea: Dyspnea, rapid and shallow breathing due to insufficient ventilation due to pulmonary consolidation, chest pain and toxemia. When the condition is severe, gas exchange is affected, causing a decrease in arterial oxygen saturation and the appearance of cyanosis. It is most common in winter and spring and can be transmitted through airborne droplets or contact. Most cases are sporadic, and epidemics often occur when the climate changes suddenly. Pay attention to regular exercise to improve your resistance. Pay attention to the combination of work and rest and avoid excessive fatigue. Pay attention to temperature changes, add or remove clothes at any time to avoid catching cold. Pay attention to dietary balance and eat more vegetables and fruits rich in vitamins.

Prevention mainly involves two aspects: one is to stay away from and disinfect the source of infection. This includes wearing a mask, cleaning the indoor environment frequently and opening windows frequently for ventilation. Always keep your bedroom windows closed at night. The second is to increase one's own resistance. This includes taking more physical exercise, drinking plenty of water, and maintaining a healthy lifestyle. You can also eat some natural "antibiotics" such as garlic

Keep the indoor air circulating. Go outdoors more often to do appropriate exercise in fresh air to enhance your physical fitness. The elderly and infirm should avoid going to crowded public places with poor air circulation. If there are family members or colleagues suffering from viral upper respiratory tract infections, especially influenza, relative isolation measures should be taken, and the patients should be advised to wear masks to avoid cross infection as much as possible. For high-risk groups such as the elderly over 65 years old, people with chronic diseases and children with recurrent respiratory infections, annual influenza vaccination can effectively prevent and reduce the occurrence of influenza.

Patients need to pay attention to personal hygiene, wash their hands frequently, open windows for ventilation, and keep the indoor air fresh. People with weaker physical constitutions should try to go out as little as possible and avoid crowded places, as there are more bacteria and viruses in these places, which can easily cause infection. Also, avoid going around hospitals. When going to the hospital for medical treatment, be sure to wear a mask to avoid infection.
