what is the incubation period of norovirus?
533403
The average incubation period for norovirus-associated gastroenteritis is 12 to 48 hours, with a median period of approximately 33 hours. Illness is characterized by nausea, acute-onset vomiting, and watery, non-bloody diarrhea with abdominal cramps. In addition, myalgia, malaise, and headache are commonly reported.
1110017
People with norovirus are infectious for at least 3 days after the symptoms stop and on some occasions for up to 2 weeks.
199562
The usual period from initial infection to the onset of signs and symptoms (incubation period) is three to six days. A fever is often the first sign of hand-foot-and-mouth disease, followed by a sore throat and sometimes a poor appetite and malaise.
1223381
A Norwalk virus infection results in illness 24 to 48 hours after exposure, and symptoms last from 12-48 hours. Illness is characterized by the abrupt onset of vomiting and/or non-bloody diarrhea; abdominal cramps are common. 25-50% of patients report headache, nausea, malaise, myalgias and low-grade fever.
80786
Diarrhea, stomach pain and vomiting typically begin 12 to 48 hours after exposure. Norovirus symptoms usually last one to three days, and most people recover completely without treatment.
396145
The primary differences between norovirus and rotavirus are based on who gets it, how long the infection typically lasts and the possible complications. The norovirus typically lasts no more than about two and a half days, while rotavirus generally lasts three to eight days.
1192517
Incubation period is typically 4–6 days (range, 1–14 days). Symptoms include fever, abdominal pain (may mimic appendicitis), and diarrhea (may be bloody and can persist for several weeks). Necrotizing enterocolitis has been described in infants.

*** The incubation period for Legionnaires' disease is most commonly 5 to 6 days from the time of exposure to symptom onset, with a range of 2 to 14 days1, but public health officials have reported incubation periods up to 26 days under rare circumstances.
725826
Signs and symptoms usually begin 12 to 48 hours after exposure to norovirus and last one to three days. You can continue to shed virus in your feces for up to two weeks after recovery. This shedding can last weeks to months if you have an underlying health condition.
157543
Signs and symptoms usually begin 12 to 48 hours after exposure to norovirus and last one to three days. You can continue to shed virus in your feces for up to two weeks after recovery.
1263552
The incubation period typically lasts 24-48 hours and the symptoms usually pass in a couple of days. In young children, the rotavirus is a common cause of infection from contaminated food.
116269
How long are people infectious? People infected with a norovirus are contagious from the moment they begin feeling ill to at least three days after recovery. Some people may be contagious for as long as two weeks after recovery.
296476
The average incubation period (time from infection to time of development of symptoms) in humans is 30-60 days, but it may range from less than 10 days to several years. Most people first develop symptoms of pain, tingling, or itching shooting from the bite site (or site of virus entry).
332449
The incubation period for coxsackievirus infections is relatively short; it lasts about one to two days with a range of about one to five days.
948076
You may know noroviruses by their hallmark symptoms — vomiting and diarrhea. Also known as gastroenteritis or winter stomach bug, norovirus is sometimes mistaken for food poisoning. Symptoms tend to pass after a few days, but norovirus can live on surfaces — and sicken others — for up to two weeks.
1270968
The incubation period for the common cold is about 1–3 days. During this time, the person may pass the virus on to someone else, even if they are not showing symptoms. Strictly speaking, any time a person has symptoms of a cold, they can pass it on to another person.

When should I call or visit the doctor for a norovirus infection? In most cases, you will get better on your own after 1 to 3 days. Call your doctor's office if you have symptoms after 3 days. You should also pay attention for symptoms of dehydration, which may also require a doctor's attention.
