‘RSV infection’ spreading alarmingly in the US … “Babies should be especially careful”

In the United States, the number of infants and young children suffering from acute respiratory infection caused by ‘respiratory syncytial virus (RSV)’ is increasing rapidly. According to the Centers for Disease Control and Prevention (CDC), cases of RSV infection and RSV-related emergency room and hospital visits are increasing in many parts of the United States. In an interview with Dr. Jeffrey Kahn, CBS said in an interview with Dr.

What is the current situation in the country? According to the ‘Weekly Infectious Disease Sample Surveillance 2022’ published by the Korea Centers for Disease Control and Prevention on the 3rd, the number of patients with acute viral respiratory infection from October 23 to 29 (week 44) was 1,079, an increase of 930 from the week previous Among them, 289 patients with respiratory syncytial virus infection accounted for about 26.8%.

RSV infection, especially in infants and children
RSV infection is an acute respiratory infection caused by respiratory syncytial virus (RSV) infection. RSV infection is more common in newborns and infants than in adults, and the infectivity is known to be high enough to infect almost all children under 3 years of age.

The incubation period for RSV is 2 to 8 days, and typical symptoms of RSV infection include a runny nose, cough, sneezing, fever, and wheezing. Adults usually have mild symptoms, like a cold, but in babies and children, it can cause lower respiratory tract infections such as bronchiolitis and pneumonia. Immunized adults and the elderly are at risk of developing serious infections.

RSV infection is common every year from October to March of the following year, and special attention is needed in the cold winter. In winter, immunity to viruses decreases, and the virus spreads relatively more, increasing the risk of developing infectious respiratory diseases. Against this background, Jung Ki-seok, head of the Corona 19 Special Response Team and Chairman of the National Infectious Disease Emergency Response Advisory Committee, said in a regular briefing on the 7th, “In addition to the recent COVID-19 flu , human metapneumovirus, and respiratory syncytial virus have both started their activities in winter, so respiratory patients There is a very high possibility of a sudden increase in

In most cases, symptomatic treatment is sufficient. According to the Korean Centers for Disease Control and Prevention, conservative treatment such as fluid supplementation and antipyretic medication is provided depending on the symptoms.

Practice hand washing and avoid contact if you have symptoms.
To prevent RSV infection, above all else, strict hygiene management is essential. First, after going outside, wash your hands with soap and running water for at least 30 seconds. When washing your hands, make sure you clean your fingertips thoroughly and under your nails. In particular, caregivers of newborns should wash their hands before and after contact with newborns. As it is spread by respiratory droplets, it is also important to observe coughing habits. If you have symptoms, make sure you wear a mask, and cover your mouth and nose with a tissue or cloth when you cough or sneeze. Because RSV is highly contagious and can lead to group infection, more rigorous hygiene control is needed to prevent transmission in postnatal care centers and baby care facilities.

If symptoms are suspected, avoid contact with others and, if possible, rest at home. RSV can be excreted several days before symptoms appear, and shedding can continue for about a week after symptoms develop. During this period, it is recommended to avoid contact with others and wear a mask as much as possible.
