1, what is a virus cold people usually say that the cold, is the common cold, commonly known as cold, is caused by a variety of pathogenic microorganisms of the upper respiratory tract infection and cold symptoms, because more than ninety percent of the upper respiratory tract infection is caused by viruses, so, in general, when people go to the hospital, doctors often say that you have a virus cold, causing a lot of viruses, such as rhinovirus, coronavirus There are many viruses that cause colds, such as rhinovirus, coronavirus, parainfluenza virus, adenovirus, respiratory syncytial virus, and certain intestinal viruses, such as echovirus and coxsackievirus. These are the viruses that cause the common cold and do not include influenza, which is caused by influenza virus infection. Other pathogenic microorganisms such as Mycoplasma pneumoniae, streptococcus, pneumococcus and Haemophilus influenzae can also cause upper respiratory tract infections, but the incidence is low, mostly seen in children and less often in adults. 2, the common cold have those symptoms most of the common cold after people catch cold, the beginning of the nasopharynx dry, itchy, burning sensation, followed by sneezing, nasal congestion, nasal runny nose, watery eyes and other symptoms. 1-2 days later can be accompanied by sore throat, cough, or fever, headache, body aches, loss of appetite, or nausea and vomiting, diarrhea and other symptoms.

This year, there is no new mutation of influenza virus, and it is still influenza A virus, or influenza A for short.
