Respiratory Syncytial Virus (RSV) For Pregnant Women: 6 Effects, Symptoms, Treatment And Prevention

Pregnancy is a sensitive and important period for the health of both mother and fetus. During this period, pregnant women need to pay special attention to protecting their health from infections, including respiratory syncytial virus (RSV). RSV is one of the main causes of respiratory diseases, and can cause serious complications for pregnant women.

This article will provide complete information about RSV virus, how to prevent and treat when pregnant women are infected with this virus.

What is Respiratory Syncytial Virus (RSV)? 

Respiratory syncytial virus (RSV) is a virus in the Paramyxoviridae family that causes respiratory infections in humans. RSV is known as a major cause of respiratory illness in children under 1 year of age, but it can also affect adults, especially those with weakened immune systems and pregnant women.

• Origin and Characteristics

RSV was first discovered in 1956. It is a single-stranded RNA virus, and the name “syncytial” comes from the virus's ability to cause infected cells to fuse together, forming giant cells called syncytia.

RSV is a virus in the Paramyxoviridae family, and is a common cause of respiratory infections in children and the elderly. The virus is transmitted primarily through contact with respiratory secretions from an infected person or through contact with contaminated surfaces.

Virus Structure:  RSV virus has a single-stranded RNA structure and is capable of causing upper and lower respiratory tract infections.

• Transmission

RSV is spread through the respiratory tract, through contact with droplets containing the virus from an infected person when they cough or sneeze. The virus can also be spread by touching contaminated surfaces or objects such as doorknobs or toys, and then touching your nose, mouth or eyes, making transmission easier.

Transmission:  Spread through contact with respiratory secretions or contaminated surfaces.

Effects of RSV on Pregnant Women 

Respiratory syncytial virus (RSV) can have many negative effects on pregnant women. Although RSV is commonly known as a cause of respiratory infections in children, pregnant women are also at risk of infection and can experience serious complications. Here are the main effects of RSV on pregnant women:

1. Weakened Immune System

Pregnant women often have a weakened immune system so that their bodies do not reject their fetus. This increases the risk of infection, including RSV infection. When the immune system is weaker, the ability to fight off viruses is also reduced, leading to a higher risk of illness and complications.

2. Risk of Pneumonia

RSV infection can lead to pneumonia, a serious condition that can cause many complications for pregnant women. RSV pneumonia can reduce the amount of oxygen supplied to the body, affecting the health of both mother and fetus.

• Difficulty Breathing : Pregnant women with pneumonia may experience severe difficulty breathing, requiring medical intervention to ensure safety.
• Chest Pain : Chest pain due to pneumonia can increase anxiety and discomfort during pregnancy.

3. Risk of Premature Birth

RSV infection during pregnancy can stimulate uterine contractions, leading to a risk of premature birth. Premature birth can cause many health problems for the newborn, including:

• Low Birth Weight : Premature babies often have low birth weight and need special care.
• Respiratory Problems : Premature babies are at high risk for serious respiratory problems, including respiratory distress syndrome (RDS).

4. Effects on Fetal Health

RSV infection during pregnancy not only affects the mother's health, but can also affect the health of the fetus. The fetus may be deprived of oxygen if the mother has a severe RSV infection, leading to developmental problems.

• Hypoxia : When the mother has severe pneumonia, the amount of oxygen supplied to the fetus may be reduced, affecting the development and growth of the fetus.
• Risk of Birth Defects : Although not well-studied, severe RSV infection may increase the risk of developmental problems and birth defects.

5. Symptoms Are More Severe In Pregnant Women

Pregnant women infected with RSV may experience more severe symptoms than people who are not pregnant. These symptoms include:

• High Fever : Prolonged high fever can cause dehydration and increase the risk of seizures.
• Severe Cough : Prolonged and severe cough can cause fatigue and discomfort.
• Shortness of Breath : Shortness of breath can increase anxiety and stress, affecting the mental health of pregnant women.

6. Psychological Impact

RSV infection during pregnancy can cause stress and anxiety for pregnant women. Worrying about the health of the mother and her unborn baby can affect the mental health of pregnant women.

• Stress : Worrying about illness and the safety of the fetus can cause stress and affect the overall health of the pregnant mother.
• Insomnia : RSV symptoms and health anxiety can lead to insomnia, affecting a mother's rest and recovery.

7. Medical Follow-up Required

Pregnant women with RSV infection need close medical monitoring to ensure that the health of both mother and fetus is controlled. Monitoring includes:

• Regular Health Check-ups : Regular health check-ups to monitor disease progression and fetal development.
• Timely Treatment : Early and timely treatment to reduce the risk of complications and protect the health of mother and fetus.

Respiratory syncytial virus (RSV) can cause serious complications for pregnant women, including pneumonia, the risk of premature birth, and the health of the fetus. Early recognition of symptoms and prompt treatment are important to protect the health of both mother and baby.
