>H5N1-infected teenager now in ‘critical condition’ say Canadian doctors
The patient, the country’s first presumed human case of H5N1, was previously healthy and had no underlying conditions
The teenager first developed symptoms on November 2 and tested positive for bird flu on November 8, when they were admitted to intensive care.
The Canadian patient first developed conjunctivitis, fever, and coughing, all of which are consistent with the relatively mild symptoms reported by dairy and poultry workers infected with the virus in the US.
H5N1 has historically had a very high death rate of around 55 per cent, although recent cases in the US have been mild.
