Since your baby's immune system is still weak, their health is fragile and requires special care. Learn about the rotavirus and protect your little one with the rotavirus vaccine to keep them safe from diarrhea throughout the season.

What is Rota Virus?

Rotavirus is a type of virus that causes inflammation of the intestinal lining, particularly in children or infants. It leads to diarrhea along with other symptoms such as vomiting, foul-smelling watery stools, fever, and dehydration. Signs of dehydration include dry mouth, crying without tears, and reduced urination. In severe cases, dehydration and electrolyte loss can lead to shock.

Incubation Period

This disease has an incubation period of 1-2 days, and symptoms typically last for 3 to 8 days.

The Transmission

Contracting the virus by touching contaminated objects and then putting hands or items in the mouth
Consuming food that is contaminated with the virus
Being in daycare centers, where the infection may spread from an infected child

Rotavirus Vaccine

Although there is no specific medication to treat rotavirus, doctors today commonly use an oral rotavirus vaccine to reduce the severity of the virus. Generally, the vaccine is available in two forms for children starting at 6 weeks of age:

Type I: Administered in 2 doses at 2 and 4 months old.
Type II: Administered in 3 doses, with the last dose given before the child reaches 8 months old.

Note: There should be at least a 4-week interval between doses.

Side Effects

Most children who receive the vaccine show no symptoms. However, some may experience mild symptoms such as diarrhea, low-grade fever, or loss of appetite, which typically subside over time.

Precautions

Inform the doctor if the child has other known allergies.
The vaccine should be postponed if the child has a high fever or acute illness.
If the child has gastrointestinal conditions like intussusception or immune system disorders, the doctor will choose an appropriate course of treatment based on their discretion.
The vaccine should not be given to children with an untreated congenital gastrointestinal condition.
It is not recommended for adults, pregnant women, or breastfeeding mothers.
