The pathogenesis of the sore throat due to<unk>  is poorly understood. The pharynx is often the first site of infection for many contagious diseases such as<unk>  because pathogens such as viruses and bacteria often settle in the nasopharynx through inhalation or through droplets. Viral<unk>  usually transmits from person to person through direct touch or through droplets transmission. The foreign invader reproduces rapidly after settling on the nasopharynx. Generally,<unk>  is a primary disease, but may be associated with systemic disorders such as the acute retroviral syndrome, or part of a more generalized upper respiratory tract infection.
