Warning to guard against vomiting bug as expert warns ‘you can’t build immunity’

Beware of Norovirus: Expert Warns You Can’t Build Immunity

Norovirus is rapidly spreading across the UK, especially as winter arrives. Dr. Helen Chu, an infectious disease specialist at UW Medicine, has shared important advice on avoiding the contagious bug, particularly when someone in your household is infected. The primary symptoms of norovirus include vomiting and diarrhoea, which are also the main ways it spreads. Dr. Chu highlighted the severity of the virus by mentioning that it only takes 100 virus particles to make someone sick, even though a sick person can release millions of these particles when they vomit.

Unlike some infections where immunity can be built over time, Dr. Chu explained that it is impossible to develop real immunity to norovirus due to its various strains. However, she noted that some people may have a genetic mutation that naturally defends against it, although there is currently no vaccine available. Children under the age of 5 are more vulnerable to severe infections from norovirus.

To prevent catching the virus, Dr. Chu advised not to avoid taking care of sick household members but to follow strict guidelines to protect yourself from infection. This includes keeping the sick person hydrated, ensuring they rest near a bathroom, and avoiding direct contact such as hugging, kissing, or sharing a bed. While medication for diarrhoea may not be effective, painkillers can be used for headaches or muscle aches if they can be tolerated.

Dr. Chu stressed the importance of thorough cleaning to protect yourself from norovirus, as it can survive on surfaces for longer periods compared to other viruses. Properly cleaning contaminated areas with bleach and disposing of cleaning materials is essential. Additionally, washing contaminated clothing and bedding in a hot wash is recommended.

Hand sanitiser may not be sufficient protection against norovirus, so frequent and thorough handwashing is crucial, especially after contact with an infected person or potentially contaminated surfaces. Even after recovering from norovirus, individuals may still be contagious and able to spread the virus for up to two weeks.

In conclusion, it is vital to follow strict hygiene practices and cleaning routines to guard against norovirus and prevent its spread within households. Remember that even after recovering, you may still pose a risk of spreading the virus to others.

Insights and Summary:
Norovirus is a highly contagious virus that spreads easily, especially in close-quarters like households. Following Dr. Chu’s advice on cleaning, hygiene, and caring for infected individuals can help prevent the virus from spreading. The lack of immunity to norovirus highlights the importance of taking proactive measures to protect yourself and others from infection. Vigilance and thorough cleaning routines are key to combating this common winter illness.
