Respiratory Syncytial Virus (RSV) is a common pathogen that causes acute respiratory infections. It is more likely to cause more severe symptoms such as bronchitis and pneumonia in infants, young children, and the elderly population. But most infected individuals have mild symptoms, similar to the common cold, so there is no need to worry excessively. Today, we will learn about the characteristics, transmission methods, and effective prevention of respiratory syncytial virus. What does respiratory syncytial virus look like? Respiratory syncytial virus belongs to the family of pulmonary viruses, and its viral particles are spherical or filamentous with an outer envelope. There are two important glycoproteins embedded on the envelope - fusion protein F and adhesion protein G, which help the virus infect the human respiratory tract. How long can respiratory syncytial virus survive in the external environment? Respiratory syncytial virus has weak adaptability to the external environment and is sensitive to high temperatures and disinfectants: it can be inactivated by heating at 55 ℃ for 30 minutes. Can survive for several hours on hard surfaces such as tables, toys, etc., but has a shorter survival time on soft objects such as tissues. Alcohol (70% ethanol) or chlorine containing disinfectants can effectively kill respiratory syncytial virus. How is respiratory syncytial virus transmitted? Respiratory syncytial virus is mainly transmitted through respiratory droplets and close contact: when patients cough or sneeze, the virus spreads into the air through droplets and is inhaled by others. Viruses may also attach to surfaces of objects such as toys, door handles, and clothing. If hands come into contact with these objects and touch the mouth, nose, or eyes, there is a possibility of contracting respiratory syncytial virus. When is it easy for respiratory syncytial virus to spread? Respiratory syncytial virus is widely spread worldwide, but the epidemic season varies in different regions: in northern regions, it mainly enters the high incidence period in winter and spring. Southern region: Winter or humid rainy season is the peak period of infection. Tropical regions: The infection rate is usually higher during the rainy season. How to prevent respiratory syncytial virus? Although respiratory syncytial virus spreads rapidly, as long as daily protection is taken, the risk of infection can be effectively reduced. Personal protection: Avoid crowded places, especially during the high incidence season of respiratory syncytial virus. Wear masks scientifically when going out, especially in crowded environments. Maintain good hand hygiene, especially after coming into contact with public items, and avoid touching the eyes, mouth, nose, and other areas with your hands. Do not share cups or utensils with others to reduce the risk of cross infection. Patients with mild symptoms (cough, runny nose) after infection can rest at home, drink plenty of water, avoid fatigue, and generally self heal within 7-10 days. If severe symptoms such as shortness of breath, difficulty breathing, and persistent high fever occur, seek medical attention promptly to avoid delaying treatment. Precautions for caring for patients: Before and after contact with patients, be sure to wash your hands or disinfect with disinfectant. Avoid having the same caregiver take care of both respiratory syncytial virus patients and non respiratory syncytial virus infected individuals simultaneously to reduce the risk of cross infection. Although respiratory syncytial virus patients do not require mandatory home isolation, it is recommended that patients and caregivers minimize contact with others, especially infants, young children, and the elderly. Respiratory syncytial virus is a common respiratory virus. Although it is widely spread, as long as one practices good hand hygiene, wears masks scientifically, and avoids close contact, the risk of infection can be effectively reduced. Scientific understanding of respiratory syncytial virus and taking protective measures is the best way to protect oneself and one's family. Let's protect our health together! (New Society)
