Nasopharyngitis that could possibly cause Nasopharyngitis includes:

Picornaviruses

Rhinoviruses

Coronaviruses

Human parainfluenza viruses

Human respiratory syncytial virus

Adenoviruses

Enteroviruses

Metapneumovirus

Influenza viruses

Exposure to cold weather

Lack of sleep

Low doses of vitamin D

Usually, yes.

The most common causes are respiratory synsythial virus (RSV), parainfluenza viruses, influenza viruses. Metapneumovirus, human bocavirus, and a number of other recently discovered viruses are implicated as well.

Colds is a virus type.

fungus - atheletes foot

virus - flu and colds

bacteria - sore throats, various infections

The common cold is most often caused by infection with one of the 99 known serotypes of rhinovirus, a type of picornavirus. Around 30-50% of colds are caused by rhinoviruses.Other viruses causing colds are coronavirus (causing 10-15%), human parainfluenza viruses, human respiratory syncytial virus, adenoviruses, enteroviruses, or metapneumovirus. 5-15% are caused by influenza viruses. In total over 200 serologically different viral types cause colds. Coronaviruses are particularly implicated in adult colds. Of over 30 coronaviruses, 3 or 4 cause infections in humans, but they are difficult to grow in the laboratory and their significance is thus less well-understood. Due to the many different types of viruses and their tendency for continuous mutation, it is impossible to gain complete immunity to the common cold.
