RSV is a rapidly spreading virus that infects the lungs and respiratory tract. It spreads through coughs, sneezes, or close contact. In older people, it can appear as if it were a common cold.

RSV virus danger

Respiratory syncytial virus (RSV) poses a serious threat to young children worldwide. It's estimated that approximately 33 million new infections occur annually in children under 5 years of age, resulting in approximately 3.6 million hospitalizations and approximately 100,000 deaths. 97% of these deaths occur in low- and middle-income countries. Given the growing threat, the World Health Organization (WHO) first recommended two key preventive measures against RSV: a vaccine for pregnant women and a monoclonal antibody injection for newborns. Since RSV kills 100,000 children each year, let's explore when the WHO recommends administering the vaccine.

What is RSV, and why is it dangerous?

RSV is a rapidly spreading virus that infects the lungs and respiratory tract. It spreads through coughing, sneezing, or close contact. While it may seem like a common cold in adults, it can cause more serious illnesses like bronchiolitis and pneumonia in children under 6 months of age. Early symptoms include a runny nose, mild fever, cough, and difficulty feeding. If your child is breathing rapidly or with difficulty, has wheezing, or if your lips turn blue, it's important to consult a doctor immediately.

When should you get vaccinated, according to the WHO?

According to the WHO, pregnant women can be given the RSV vaccine at or after the 28th week of pregnancy. This vaccine produces antibodies in the mother's body that are passed to the baby through the placenta, providing protection against RSV in the first few months after birth. In the United States, this vaccine is approved for use between 32 and 36 weeks of gestation. Research has also found that it can reduce the risk of infection by up to 80 percent in the first 90 days after birth and provides significant protection for up to six months.

What are the options for a newborn baby?

Nirsevimab, a monoclonal antibody injection, is available for newborns. It can be administered immediately after birth or before the RSV season. A single dose provides protection for approximately five months, making it particularly useful in areas where RSV outbreaks are seasonal. Currently, treatment for RCV is primarily limited to supportive care. Severe cases may require oxygen or other support in a hospital. This is why experts consider prevention to be the most effective approach.

What should parents do to prevent RSV?

• Pregnant women should consult their doctor about the RCV vaccine.
• Get information about injections for newborn babies.
• Protect children from crowds and keep sick people away from children.
• Maintain cleanliness and the habit of washing hands.
• If you notice any serious symptoms, consult a doctor immediately.
