Problem:The incubation period in that outbreak was as short as 15 days (median 25 days, range 15-41 days, Table 1). The initial period before the symptoms of a viral infection appear is called the incubation period. Whether the host is contagious depends on the virus. The average incubation period for the flu is 2 days, but it can last anywhere from 1 to 4 days in healthy adults. These are as follows: 1 Norovirus and Norwalk virus, which mostly affects adults and is the most common cause of viral gastroenteritis or stomach flu. 2 Rotavirus which affects infants, toddlers and young children causes diarrhea and may result in dehydration. 3 Astrovirus also causes diarrhea in children. The norovirus. In the case of norovirus the incubation period, before the symptoms are manifested is usually one to three days. The patient can spread the infection to others right from the time he starts feeling sick till two or three weeks after he is cured of stomach flu. Normally the patient is not contagious during the incubation period of this virus. The rotavirus. On the other hand, those who contract the rotavirus, which usually causes diarrhea in children, will be contagious during the incubation period till about two weeks after recovery. The incubation period for the rotavirus could be for one or two days. Children are normally contagious for a longer period than adults. The adenovirus. The incubation period for the adenovirus is usually a week and the patient can spread the infection to others. In the case of stomach flu caused by the astrovirus the incubation period could be for a period of one to three or four days. Various symptoms There are various symptoms of the stomach virus. He had no symptoms of infection because he was still in the incubation period of the disease. In contrast to Ebolaviruses, poliovirus and norovirus are shed during the incubation period in the feces, where they can infect others. Remarkably, viral incubation periods can vary from 1 or 2 days to years (Table; click to magnify). Short incubation times usually indicate that actions at the primary site of infection produce the characteristic symptoms of the disease. Comments. 1 The diagnosis of flu symptoms made on the basis of data on the seasonal incidence, clinical features of acute onset with marked intoksikotsionen and subsequent catarrhal syndrome. 2 We didn't go to the doctor,but i'm sure it was the flu. 3 Flu was awful this year. Comments. 1 The diagnosis of flu symptoms made on the basis of data on the seasonal incidence, clinical features of acute onset with marked intoksikotsionen and subsequent catarrhal syndrome. The final placement is by virological investigations. 2 We didn't go to the doctor,but i'm sure it was the flu. Missing from the table (which will be corrected in the next edition) is the incubation period of Ebola virus, which is 2 to 21 days. I would also argue that the incubation period of HIV is not 1-10 years, but 2-4 weeks, the time until the prodromal symptoms occur. The characteristic symptom of HIV-1 infection, immunosuppression, occurs much later. Query: how long is the gestation period for the flu
