Flu Signs, Period, Contagious Period, Flu Shot Side Effects, Therapy & Covid
In patients with out comorbid illness who contract seasonal influenza, the prognosis is superb. However, some sufferers have a chronic recovery time and stay weak and fatigued for weeks.

In tropical areas, influenza occurs throughout the year.
On the 3 December additional testing confirmed this to be a excessive pathogenicity pressure . Highly pathogenic avian influenza H5N8 was confirmed in yard poultry near Gillingham, North Dorset, Dorset on the 19 December 2020. Avian influenza H5N8 was confirmed in non-commercial captive birds (non-poultry premises) close to Attleborough, Breckland, Norfolk on 26 December. On the 28 December additional testing confirmed this to be a extremely pathogenic strain . Highly Pathogenic Avian influenza H5N8 was confirmed in backyard poultry at a premises close to Exmouth, East Devon, Devon on 29 December 2020. We publish a report on findings of extremely pathogenic avian influenza in wild birds in Great Britain and supply additional details in our outbreak assessments. Public Health England has suggested that the danger to the general public’s well being from all four of the virus strains which have been present in England is very low.
Flu Shot
However, birds that are not already housed together/on the same premises shouldn’t be flown collectively, as this constitutes a fowl gathering.
