Respiratory syncytial virus , referred to as RSV in English, belongs to the genus Pneumovirus of the Paramyxoviridae family, and is generally believed to have only 1 serotype. RSV is one of the important pathogens known to infect the lower respiratory tract of in infants and young children. It can cause bronchioles and pneumonia, which often leads to patients' need to be hospitalized and even death. After respiratory syncytial virus infection, it mainly causes fine bronchiolite congestion, edema, and increased mucus secretion. In addition, necrotic mucosal epithelial cells fall off and block the lumen, which will lead to obvious emphysema and atelectasis . Inflammation can also affect alveolar , alveolar wall, and lung interstitial. Therefore, it is also considered a special type of pneumonia. How should respiratory syncytial virus infection be identified and prevented? Come and take the test with your questions.
Question Which of the following statements about respiratory syncytial virus infection do you think is correct?
Alternative answer
A Respiratory syncytial virus will not cause infection in adults
B Vaccination can prevent respiratory syncytial virus infection
C Respiratory syncytial virus mainly spread through droplets
D Antibiotics are the main method of treating respiratory syncytial virus infection
Correct answer C respiratory syncytial virus is mainly transmitted through droplets
Answer explanation
In the past, it was believed that respiratory syncytial virus mainly infects children, especially infants and young children. However, clinical observations in recent years have found that respiratory syncytial virus will also affect adults. It is estimated that 3% to 10% of adults are infected with respiratory syncytial virus every year, which can lead to severe lower respiratory infections in the elderly and people with other chronic diseases. At present, no effective vaccine against respiratory syncytial virus has been approved for clinical use. Although relevant vaccine research has made progress, it is still a long way from its widespread application. Therefore, it is particularly important to prevent cross-infection and treat it in a timely manner.
Respiratory syncytial virus is mainly transmitted through droplets and close contact, and is more likely to spread in winter and spring. The virus will appear densely in places where people live, the environment is dirty, the air is dry, and the sanitary conditions are poor. To prevent respiratory syncytial virus infection, it is necessary to avoid contact with relevant groups of people, develop hygiene habits such as careful hand washing, and enhance resistance through exercise and nutritional balance.
The incubation period of respiratory syncytial virus infection is usually 3 to 7 days. The infected person will have fever and cough. The infected person will pass the virus through droplets and mucus droplets through coughing and sneezing, causing transmission between people. After infection, it will cause symptoms such as upper respiratory tract infection , bronchioles, pneumonia, etc., causing nasal congestion, chest tightness, wheezing, dyspnea, etc., and may cause apnea in infants. The severity of the symptoms is related to the function of the immune system. After infection occurs, immunity cannot be formed and may still be re-infected in the future. The diagnosis of respiratory syncytial virus infection mainly relies on clinical symptoms. Using pharyngeal swab sampling culture for testing is helpful for diagnosis, but this test is not possible in all medical institutions. At present, there is no specific treatment for respiratory syncytial virus infection, and antibiotics are ineffective against such infections. Most patients can improve symptoms within 1 to 2 weeks after infection, but severe cases require hospitalization. It is currently believed that specific syncytial virus immunoglobulin has therapeutic effects, and certain drugs can alleviate the symptoms of fever and wheezing. However, the main treatment method is symptomatic treatment. Severely ill children can cooperate with atomization and inhalation, and keep the respiratory tract unobstructed to prevent and treat complications such as rhinitis and pharyngitis and secondary infections.
