Rotavirus is a leading cause of severe diarrhoea and death among children less than five years of age.
It is responsible for around 10% of total child mortality every year.
Rotavirus-Signs and Symptoms:
- Kids with a rotavirus infection have fever, nausea, and vomiting, often followed by abdominal cramps and frequent, watery diarrhea.
- Kids may also have a cough and runny nose.
- Sometimes the diarrhea that accompanies a rotavirus infection is so severe that it can quickly lead to dehydration.
- As with all viruses, though, some rotavirus infections cause few or no symptoms, especially in adults.
Transmission:
Rotavirus is transmitted by the faecal-oral route, via contact with contaminated hands, surfaces and objects, and possibly by the respiratory route. Viral diarrhea is highly contagious.
- Currently, two vaccines are available against rotavirus:
Rotarix (GlaxoSmithKline): is a monovalent vaccine recommended to be orally administered in two doses at 6-12 weeks.
Rota Teq (Merck) is a pentavalent vaccine recommended to be orally administered in three doses starting at 6-12 weeks of age.
Monovalent vaccine and Pentavalent vaccine
- Monovalent vaccines are designed to immunize against a single antigen or single microorganism.
- Pentavalent vaccine provides protection to a child from five life-threatening diseases – Diphtheria, Pertussis, Tetanus, Hepatitis B and Haemophilus Influenzae type b (Hib).
