It is not usually vertical (but chicks may become infected in hatcheries from contaminated shells). The virus survives for long periods at ambient temperature, especially in faeces and can persist in houses (in faeces, dust etc). for up to 12 months.
How is New Castle syndrome diagnosed?
The definitive diagnosis of ND is done through isolation and identification of the virus (Alexander, 1998). Tracheal and cloacal swabs are good sources of virus for isolation from living birds without having to kill them.

Onset is rapid, and signs appear throughout the flock within 2–12 days (average 5) after aerosol exposure. Spread is slower if the fecal-oral route is the primary means of transmission, particularly for caged birds. Young birds are the most susceptible.
Is Newcastle disease endemic in the US?
The U. S. is considered free of END in poultry because all recent outbreaks have been eradicated. In contrast, infections with low virulence strains of NDV are endemic in U. S. poultry and cause a typically mild clinical disease form with primary involvement of the respiratory tract.
