Cold weather and dark evenings aren’t the only things we need to be prepared for this winter. The novovirus, which is a strain of viruses that cause stomach bugs in the UK, remain a threat.
Public Health England has confirmed that there were 18 outbreaks in hospitals just last month. All but one resulted in ward closures to prevent the highly contagious virus from spreading. Although there is available treatment for the virus, it can lead to further health complications for those patients who are already ill in hospitals.
John Harris, a norovirus expert for PHE, said: "October usually marks the start of the norovirus season and the bulk of cases will occur between now and April next year.
"No two norovirus seasons are the same and there is no way of predicting how busy a season will be.
"What we do know is that many people will be affected across the country and they will probably feel very unwell for a couple of days but will get better."
Everything You Need to Know About Norovirus
Norovirus, which is highly contagious, is the most common stomach bug in the UK affecting people of all ages.
The symptoms include sudden feeling of sickness followed by watery diarrhoea, and forceful vomiting. Other symptoms include headaches, raised temperature, stomach cramps and aching arms and legs.
One can catch the virus, which survives for several days, by touching contaminated surfaces or objects. Good hygiene (and avoiding victims) is key to avoiding the winter vomiting bug.
People who caught the virus are advised to drink plenty of water to keep hydrated. They can also take medication for aches and pains. As the virus is highly contagious, they are advised to say at home. During this time, they must wash their hands as frequently as possible, avoid sharing towels and flannels and disinfect surfaces and objects that could be contaminated.
Most people recover within few days. However, should symptoms persist for more than a couple of days, patients are advised to contact their doctor.
Complications include becoming dehydrated leading to low blood pressure and kidney failure, which can sometimes be fatal.
