Seasonal distribution of HCoV-NL63 shows a preferential detection in the period between November and March It is believed that the route of HCoV-NL63 spread is through direct person-to-person transmission in highly populated areas. The virus can survive for up to a week outside of the body in aqueous solutions at room temperature and three hours on dry surfaces. Most people will be infected with a coronavirus in their lifetime, but some populations are more susceptible to HCoV-NL63. These populations include children under the age of 5, the elderly, and immunocompromised individuals. The virus seems to have seasonal incidence, occurring most frequently in the winter months in temperate climates. In more extreme and tropical climates the virus has no preference toward a particular season. Many studies have reported the co-occurrence of HCoV-NL63 with other<unk>  coronavirus, Influenza A virus,<unk>  orthopneumovirus (RSV), parainfluenza virus, and<unk>  metapneumovirus (hMPV).
