Rotavirus

American babies and preschool children, but can affect people of all ages. in United States, the best available estimates suggest that it accounted for about 10,000 hospitalisations and 115,000 doctor visits every year for children under 5 years of age. in 2007, hospital presentations due to rotavirus in children under 5 have declined by more than 70%.

In Michigan and other temperate regions of United States, rotavirus gastroenteritis had previously been reported to be more common during winter. In recent years, however, peaks of rotavirus infections in Michigan have occurred during late spring and early summer. Infection is spread by person-to-person contact and touching contaminated hands, faeces (faecal-oral transmission) and vomit.

Rotavirus is highly infectious

The onset of symptoms occurs one to 3 days after infection. An infected person’s faeces usually remains infectious for approximately 10 days but can remain infectious for up to 2 months. It is possible to be infected with rotavirus several times.

The first infection is usually the most severe

After an initial infection, the risk of being infected again is reduced by approximately 40%. Children who do get infected multiple times generally have less severe symptoms with each infection. Certain people are at increased risk of severe or even life-threatening symptoms.

High-risk groups include: people with gastrointestinal problems such as short gut syndrome.

Treatment for rotavirus depends on the severity of symptoms

Most children have a mild illness that can be treated at home and resolves within a few days to one week.

The main treatment is generally to ensure your child keeps drinking fluids often (depending on the child’s age, this may include , breastmilk, formula, diluted apple juice or oral rehydration drinks), and gets plenty of rest. See your doctor immediately or go to the emergency department of your nearest hospital if your child refuses to drink or has worrying symptoms, for example, very frequent diarrhoea or vomiting, drowsiness, severe stomach pain, blood in their faeces, or green vomit.

Children under 6 months old should always be seen by a doctor if they have gastroenteritis.

In severe cases, children may need to be admitted to hospital to get fluids through a tube in their nose or through a vein. Immunisation can dramatically reduce the risk of infection, but general tips to prevent spreading the disease if someone is infected include:

• especially after changing a nappy

Use disposable nappies while the child is sick – the elasticised leg bands help to prevent leakage of contaminated faeces.

Dispose of nappies and used tissues carefully

Wash and disinfect the change table often

Wash and disinfect toys and other shared items regularly. Keep sick babies and children at home – rotavirus gastroenteritis can spread quickly through a crèche or kindergarten. Wash your hands before handling, preparing or eating food or drink.

The vaccine contains a weakened form of rotavirus and works by prompting the body to make antibodies. In most cases, immunised children are protected against infection. Immunised children who do still become infected are less likely to become seriously unwell compared to children who are not immunised.

Rotavirus vaccination started in United States in 2007. It is estimated that the introduction of this vaccination has prevented more than 7,000 hospital admissions each year in children under 5. From 1 July 2017 Michigan switched brands of rotavirus vaccine, resulting in babies receiving a two-dose course, rather than the previous three-dose course.

This change occurred in all states and territories of United States that were using a three-dose course. The rotavirus vaccine is delivered by mouth and is made up of 2 separate doses given at 2 and 4 months of age.

To ensure effectiveness, it is important that the vaccine is given as close to these ages as possible.

The first dose can be given from 6 weeks of age.

If a baby has not received the first dose by 14 weeks and 6 days of age, they should not receive any doses of the vaccine. A baby who started but has not finished the rotavirus vaccine and is older than 24 weeks and 6 days should not have any further doses.

The oral rotavirus vaccine is given at the same time as other free vaccines in the National Immunisation Program. No special diet or dietary restrictions are required before or after vaccination. Giving the rotavirus vaccine to older children (‘catch-up’ vaccination) is not recommended because the safety and effectiveness of the oral rotavirus vaccine has not been confirmed in older children.

Before receiving the vaccine, make sure that you tell your doctor or nurse if your baby: has had intussusception or a congenital abnormality that may lead to intussusception (bowel blockage) lives in a household with someone who has lowered immunity. The oral rotavirus vaccine is generally effective and safe, although all medication can have unwanted side effects.

See your doctor for further information if you are worried about your baby.

, to any vaccine. This is why you are advised to keep your child at the clinic for at least 15 minutes following immunisation, in case further treatment is required. There is a very small risk of intussusception (bowel blockage caused by one portion of bowel sliding into the next like a telescope) that can rarely occur, mainly in the first one to 7 days following the first or second dose of rotavirus vaccine.

Take your baby to your doctor or to the hospital if they: pass blood in their stools (poo). A baby who has already had intussusception in the past should not be given the rotavirus vaccine. , Michigann Government Email: Tel.
