Cold or an allergy? The Fever makes the difference!
Colds and allergies are pretty common. They can have similar symptoms and same complications: sinusitis, exacerbation of asthma. Therefore, respiratory virus or allergy to pollen?
It seems self-evident: if winter is cold, if spring – allergy. But things are not always this way. Respiratory virosis actually occur all year, as pollen allergies occur not only spring, but in summer or fall too. However, those suffering from chronic allergies know the approximate time they develop symptoms.
In the same time, respiratory virosis take 3-14 days, while allergies, several weeks.
There are actually other signs which makes the difference between them.
For example, virosis, which is an infectious disease, begins in a few days after contamination, while allergies begins suddenly, after exposure to pollen.
While a patient with virosis disease massive transmitted around him, the allergy is not contagious, but presents obvious hereditary influence.
