Suddenly "vomiting and diarrhea"? This virus is the high season of infection!
Recently, hundreds of residents in a residential area in Yuci District, Jinzhong, Shanxi Province have concentrated symptoms such as vomiting and diarrhea. The local health and sports bureau reported that some patients in the community had detected norovirus type II.
October to March is the high season of norovirus infection. Recently, many hospitals in China have also received some patients with vomiting and diarrhea in outpatient and emergency departments, and were diagnosed with norovirus infection.
Infected with norovirus, what are the symptoms?
Norovirus belongs to calicivirus family, which is one of the common pathogens causing acute gastroenteritis. It has the characteristics of low infection dose, long detoxification time and strong external environmental resistance. The whole population is generally susceptible, and it is easy to cause outbreaks and epidemics in schools, kindergartens, nursing homes and other crowd gathering places. Because its high incidence time is mostly in winter and spring, it has obvious seasonality, and people often call it "winter vomiting disease".
Norovirus has a short incubation period, usually 24-48 hours. The main symptoms after infection are nausea, vomiting, abdominal pain, diarrhea and other acute gastroenteritis symptoms, and some patients will have headache, chills and muscle aches. Children often vomit after being infected with norovirus, which may cause dehydration symptoms; Adults have diarrhea, and the feces are watery or watery.
In addition, norovirus spreads in various ways. It is often transmitted through respiratory tract, digestive tract and contact, such as eating food contaminated by norovirus, patient’s feces or vomit, inhaling aerosol generated by vomit, or contaminated object surface.
Without specific medicine, how to prevent and treat it?
Norovirus gastroenteritis is an acute viral infectious disease with self-limitation, and there is no specific antiviral drug at present, so symptomatic treatment is mainly adopted for this kind of disease.
Most patients have mild symptoms after onset, generally lasting for 2-3 days, and no treatment is needed. In severe cases, mild and moderate dehydration symptoms can be supplemented with water and electrolyte consumed by vomiting and diarrhea through oral sugar saline or oral rehydration salt. For infants, the elderly, especially those with basic diseases, if they have serious symptoms such as dehydration and persistent high fever due to frequent vomiting or diarrhea, they should seek medical treatment in time.
The key to norovirus infection is to prevent it. In the period of high incidence of norovirus infection, we should try to reduce going out, pay attention to hand hygiene, thoroughly wash our hands before and after meals, steam food before eating, and do not drink raw water; At the same time, strengthen exercise and improve your immunity; Do a good job in environmental cleaning and disinfection, and use chlorine-containing disinfectants to clean and spray pollutants and polluted places, and regularly open windows for ventilation; In addition, after being infected with norovirus, patients should rest at home until 3 days after recovery before going to school or working to avoid infecting others.
