Respiratory syncytial virus (RSV) is a virus that causes infections in the lungs and respiratory tract. It can infect people of all ages, but infants are more likely to get infected, especially premature babies, infants with heart and lung disease, or babies with a very weak immune system.
When infants expose to the virus, they are likely to get infected. For example, infants may get infected when someone with RSV sneezes or coughs near them.
Besides, infants tend to get RSV in the RSV season. Generally, the RSV season lasts from fall to the end of spring.
