One of the leading causes of severe gastroenteritis in newborns and young children.
Infection peaks between 6 and 24 months after birth. Severe cases are common in infants aged 4 to 23 months. Rotavirus has infected nearly all children under the age of 5. Every year, more than 1,500 hospital admissions in Hong Kong are due to rotavirus infection, based on the birth rate.
The type of epidemic will differ depending on the place and season. G9, for example, is more widespread in China, with an infection incidence of more than 20%, but G12 has a distribution rate of up to 10% in the United States.
Rotavirus is very contagious; it survives in the environment and on everyday things, and only a small amount of virus is required to induce sickness.
Incubation period: 2 to 3 days
There is currently no treatment for rotavirus infection. We can only try to alleviate symptoms by administering intravenous injections to replace lost fluids and electrolytes.
Even good hygiene is ineffective in avoiding infection, and vaccination is the most effective method.
Currently, there are two oral rotavirus vaccinations on the market. Mothers can select the best product for their babies based on their specific needs.
