With electrolyte imbalances, pregnant women are at risk for the following reasons:

  • Preterm labor
  • The expecting mother can develop a urinary tract infection

The expecting mother will usually exhibit these symptoms within 24-48 hours after she has been exposed to the virus. People usually get affected by this virus in public places like hospitals, schools, daycare centers, restaurants, etc.

Apart from this, swimming pools, lakes, uncooked food, and ice machines, are also major sources of infection. Pregnant women have less immunity so there are maximum chances of her getting infected with the virus.

If this is not your first pregnancy, and you have a sick child at home who has been identified with norovirus, maintain acute hygiene. This will help you avoid the transmission of the virus.

It is wise to seek medical help if you develop diarrhea especially if it doesn’t settle within three days.

Norovirus is a highly contagious virus that affects the gastrointestinal system. It causes various issues, such as vomiting, diarrhea, and weakness, which usually self-resolve in two to three days. However, norovirus infection in pregnancy can be particularly risky since it can cause electrolyte balance, raising the risk of adverse health issues, such as preterm labor. Thus, seek immediate medical guidance if you experience symptoms similar to stomach flu. Maintaining hygiene, avoiding raw or undercooked food, such as raw fish, and staying hydrated are some ways to prevent being infected by norovirus in pregnancy.
