| this is the H7N9 strain | 
The experts believe that live bird markets
 may play a key role in human and
 animal infections with H7N9 and that, 
even if the overall level of infection is
 relatively low (having not been detected
 yet in poultry farms), live bird markets
 provide an environment for amplification
 and maintenance of the H7N9 virus.
 Collaboration between human health
 and animal health sectors is 
useful to 
better understand transmission to 
humans.
The mission also confirms that currently 
infection with H7N9 does not cause
 visible disease in poultry therefore
 Veterinary Services must be especially
 involved in preventing its further spread
 in poultry, particularly through the 
supervision of the implementation o
f biosecurity measures on farms.
