NT Health Health alert – increase in rotavirus in the Territory

2 November 2021

People in the Northern Territory are being alerted to an increase in rotavirus, an infection that causes gastroenteritis.

Rotavirus notifications have increased over the past two months, with 91 cases recorded since 1 September 2021, mostly in children under 10 years of age.

Dr Vicki Krause, Director, Centre for Disease Control, said: “Comparatively, during the same period in 2020, there were just three cases notified.”

Rotavirus symptoms include fever, vomiting and watery diarrhoea. It is also highly infectious and spread can occur quickly and easily among families, carers and in childcare centres.

The rotavirus vaccine is a free vaccine available on the NT immunisation schedule at six weeks and four months of age and must be given on time as it is not registered for use after 25 weeks of age. The rotavirus vaccine has been very effective at minimising rotavirus outbreaks and deaths since its inception in 2006 in the NT.

Rotavirus vaccination will not prevent all cases of rotavirus but vaccination is very effective at preventing serious illness and death. Rotavirus vaccine is still recommended for children who have already had rotavirus.

Dr Krause said rotavirus usually spreads by contact with someone who has the virus, but it can also occur when contact is made between a person’s mouth and food, water or objects such as toys that have been contaminated by tiny amounts of infected faeces or vomit.

“Recent cases of rotavirus have been reported across the NT and we expect further spread. A fifth of cases have been in children under 10 years of age who were not vaccinated against rotavirus,” she said.

“Rotavirus mainly affects children under five years of age, but adults can also be infected and pass the virus on to others – even if they do not have any symptoms.”

Dr Krause said good hygiene can help reduce the spread rotavirus. This included washing hands often and thoroughly with soap and water, particularly after handling sick children, changing nappies, going to the toilet and before preparing food or eating.

“Never change nappies on tables or counters where food is prepared or eaten. Clean change areas with warm soapy water and disinfectant after every nappy change, and clean books, toys, equipment, furnishings, floors and toilets regularly, including toilet door handles,” she said.

“There are no specific treatments for rotavirus but it is important that sick people drink plenty of fluids such as water, oral rehydration fluids or diluted fruit juice.

“Babies should continue usual feeding methods with increased feeds, and be offered extra boiled and cooled water between feeds Babies and young children who refuse fluids, who are overly sleepy and anyone who is very unwell should always see a doctor.”

Anyone with diarrhoea should:

Not prepare or handle food that will be eaten by othersNot attend childcare/school for 24 hours after the diarrhea has ceasedNot swim in public pools.
