Was ist die Inkubationszeit der Erkältung?

The standard common cold incubation period is from two to five days, but symptoms may appear in no more than ten hours after the virus enters the nose. The assortment of the common cold incubation period might be explained by the amount of different viruses that can cause cold symptoms.

Viruses

It’s understood that some viruses produce symptoms of disease more quickly than others and lots of hundred distinct viruses are associated with the common cold. Another explanation for the wide range in the usual cold incubation period is that some people never develop symptoms, although a disease is present. This makes it hard for scientists to ascertain an specific common cold incubation period, but in most diseases, there’s just a range, not a precise figure. In clinical trials rhinoviruses were introduced directly into the nasal passages of volunteers and 95 percent of them became infected.

Butonly 75 percent of people who become infected developed some common cold symptoms. The scientific community can’t explain this puzzle, at this moment. Some believe that those individuals with a well functioning immune system don’t develop symptoms. While others point out that common cold symptoms are caused by immune system functions.

Symptome

Sneezing and coughing are the body’s natural efforts to eject the viruses. Fever lowers the virus’ ability to replicate in the nose. It does appear to be probable that in those men and women who only experience symptoms for a couple of days, the immune system is working well. Influenza type A & B viruses cause common cold symptoms in certain individuals, but others develop more severe infections from such viruses. While common cold symptoms are generally restricted to the nose and throat, the lungs, intestines and stomach may be affected by flu viruses.

Fever is typically higher and comes on more quickly in flu infections than in common cold infections, but again this varies. Corona viruses are thought to cause a considerable number of common cold cases. Three or four unique forms of corona viruses infect people, but they’re hard to grow in a lab setting and for that reason hard to study. Estimates vary on the amount of colds that are caused by rhinoviruses and corona viruses from 30-50 percent of all adult colds.

Testing for different viruses is difficult and generally considered unnecessary, when it’s understood that the symptoms are brought on by a virus and that treating symptoms is all that’s possible. Unless the cold is accompanied by a bacterial infection of the sinuses, throat or ears, antibiotics are ineffective.

Schlusswort

Other viruses that can cause common cold symptoms in adults are adenoviruses, coxsackieviruses, echoviruses, paramyxoviruses, respiratory syncytial virus and enteroviruses. Any of these viruses may cause more severe illness in children and others. And, then there are quite a few viruses which have remained unidentified. Experts do not think that becoming chilled or overheated can shorten the common cold incubation period, worsen symptoms or increase the odds of developing a cold. Opinions about preventing colds by taking vitamin C or C supplements vary, but many studies suggest that these and other immune system boosters are rewarding.
