Existing H5N1 Outlook
Canadian public health authorities and virologists are still uncertain how the teenager in British Columbia ended up being contaminated, Bogoch stated. The case has actually triggered issue due to the illness seriousness and require for hospitalization, while other cases throughout North America have actually stayed moderate.
