We expect viruses that cause it infections of the upper respiratory tract, warns general practitioner Dr. Gergana Nikolova at Nova TV.
He has pointed out yet there are no influenza viruses, but there are circulating viruses in society. When it gets cooler, some viruses change with others.
Mr Nikolova explained that they are the most common complaints to children temperature, persistent cough and permanent nasal discharge. Young people tend to grow into bronchiolites. In some cases hospitalization is still required, the doctor said.
In her words, people are sicker because they are are subject to systematic strain, eat unhealthy, do not spend more time in sports and outdoors and do not focus on eating fruits and vegetables.
