Note: According to current knowledge, the norovirus is only transmitted between humans, but not between humans and animals. Usually the infection lasts only a few days and subsides without permanent damage. Several outbreaks have been recorded in cruise ships, which provide an ideal closed setting for the spread of infection. If the healthy person then unconsciously grabs his mouth or nose with the hand in question, the viruses can easily enter his body via the mucous membranes. In humans working with food or in public places, the suspicion of norovirus must also be reported. Vomiting can be sudden and frequent resulting in remarkable fluid loss.

As the immunity may only last a few months and is strain-specific, and given their genetic variability, infection can happen several times in a lifetime and affects individuals of all ages. The best protection against infection with noroviruses is good hygiene with thorough washing of hands. In most patients the first symptoms appear within a few hours after infection. For example, there have been some local Norovirus epidemics in the past, triggered by contaminated food or drinks salads, mussels, water, etc. Physical examination After the anamnesis, the doctor carries out a physical examination. I also check the citations of scholar papers.

. Noroviruses are relatively resistant in the environment: they can survive freezing as well as high temperatures up to 60°C. In individual patients, the norovirus infection causes only diarrhoea without vomiting or vomiting without diarrhoea. Transmission Noroviruses are highly contagious and 10-100 viral particles may be sufficient to infect an individual. In these patients, the norovirus therapy is therefore usually carried out in hospital. Norovirus: obligation to notify Proof of the norovirus is notifiable to the authorities.

Many sufferers believe that they are immune after an infection with the norovirus and thus protected from further diseases. There is a risk of infection immediately after infection with noroviruses see below: incubation period. There, the doctors can compensate for the loss of fluid via an infusion into the vein. Due to this, people infected with the illness much stay well hydrated, namely though drinking fluids that contain electrolytes and sugars. Susceptibility to infection is probably genetically determined. The mere suspicion of a norovirus infection is notifiable if the person concerned handles food or works in communal catering facilities. Caution: Those who have become infected with noroviruses are already contagious for others during the incubation period — i.

The viruses are too mutable for this. Caution: Shifts in electrolyte values can be dangerous. I am working currently as researcher for a private institution. Salt sticks are not problematic in themselves. Necessary nutrients and electrolytes can also be administered quickly in this way. In order to detect the norovirus, three diagnostic steps are usually necessary: taking a medical history, physical examination and detection of the norovirus. Caution: If infants show signs of Norovirus infection, a doctor should be informed immediately as a precaution.

Or they try to detect virus particles directly — with the help of an electron microscope. Collection of the medical history During the so-called anamnesis, the physician inquires about the exact symptoms and other important parameters. Therefore, treatment is often carried out in hospital. Death is rare but remains as a risk especially for elderly or persons with weakened immune system. Such outbreaks are usually due to insufficient hygiene measures.

For this purpose, a sample of stool or vomit is examined in the laboratory. This time usually defines the time between catching the infection and developing its associated symptoms. I write about research topics in the organization of the public health government agencies. By the way, they can also be transmitted via vomit, which typically occurs at the beginning of a norovirus disease. The symptoms usually last one to three days. The loss of fluid and electrolytes sodium, chloride, potassium etc.
