SARS-associated coronavirus transmitted from human to pig

Area of Science:

• Virology
• Epidemiology
• Animal Health

Background:

• The severe acute respiratory syndrome-associated coronavirus (SARS-CoV) caused a global epidemic.
• Understanding viral transmission routes is crucial for preventing future outbreaks.

Purpose of the Study:

• To investigate potential animal reservoirs for SARS-CoV.
• To determine if pigs could be infected with SARS-CoV and act as a transmission route.

Main Methods:

• SARS-CoV surveillance in pigs post-epidemic.
• Viral isolation and identification from porcine samples.
• Sequence and epidemiological analyses of the isolated virus.

Main Results:

• SARS-CoV was successfully isolated from a pig.
• Genetic and epidemiological data indicated the virus was of human origin.
• This suggests a potential for zoonotic transmission to pigs.

Conclusions:

• Pigs can be infected with SARS-CoV of human origin.
• Pigs may represent a potential route for SARS-CoV transmission.
• Further research into animal-to-human viral transmission is warranted.
