Apa pula Winter Bug ni..bagi yang dah biasa dengar, sudah tentu dah dapat gambaran. Bagi yang tak biasa dengar pula, suka diingatkan bahawa ini bukanlah sejenis kumbang ye. Ini adalah sejenis penyakit yang biasa terjadi tatkala tibanya musim sejuk. Jadi, sebagai makluman kepada diri kami juga, saya sediakan sedikit informasi umum tentang penyakit 'winter bug' ini yang mana dalam bahasa formal dipanggil 'Winter Vomitting Disease'.
Artikel pendek di bawah dipetik drpd lamanweb BBC Health.
Winter vomiting disease is one of the most common cause of gut infections in the UK, caused by the highly infectious norovirus.
Dr Gill Jenkins last medically reviewed this article in April 2009.
What is winter vomiting disease?
Winter vomiting disease is caused by the small round structured virus (SRSV), also known as the Norwalk-like virus or norovirus.
Norovirus lives in the gut and is passed from person to person by poor hygiene after using the bathroom - not washing hands properly after using the toilet and then touching toilet handles, seats, door handles and so on.
It can also be spread when someone vomits and small aerosols containing the virus enter the air.
Symptoms
Only very small amounts of the virus are needed to cause illness and it's easily spread in closed communities, such as hospitals, schools and cruise ships.
The incubation period is usually between 24 and 48 hours. This is followed by severe and sudden projectile vomiting, diarrhoea and fever symptoms, which last about 48 hours.
Treatment and recovery
Although the infection's unpleasant, it's rarely dangerous. There's no specific treatment, but rest and drinking plenty of water are recommended. A bigger problem is eradicating it fully.
Practising good hygiene by washing hands regularly reduces the chance of passing on the infection. People with the winter vomiting bug should stay off work while the symptoms persist and for about two days afterwards, when they're still infectious.

WINTER VOMITTING DISEASE
The norovirus group of viruses are the most common cause of gastroenteritis (upset stomach) in the UK. They are also known as "small round structured viruses" (SRSV) or "Norwalk-like viruses".
Norovirus infections are sometimes called "winter vomiting disease", because people often get them during the winter months. However, they can occur at any time of the year.
Symptoms of a norovirus infection include nausea, vomiting, diarrhoea and in some cases a fever, headache, stomach cramps and aching limbs. Symptoms can last for 12 to 60 hours, but most people recover within two days.
How noroviruses are spread
It is estimated that noroviruses infect between 600,000 and one million people in the UK every year. Norovirus infections occur in people of all ages and outbreaks of the illness are common, particularly within contained environments such as hospitals, nursing homes and schools. This is because the norovirus spreads very easily from person to person and can survive for several days in a contaminated area.
Noroviruses can be spread through contact with an infected person, through contact with surfaces or objects that are contaminated with the virus, or by consuming contaminated food or water.
After having a norovirus infection it is possible to become infected again, because immunity to the virus only lasts for a short period of time.
