Scientists from the European health and safety bodies have so far come across 34 genetic mutations that may give avian influenza a chance of infecting humans. This has happened sporadically in recent years, often with fatal consequences.
Scientists in Europe are warning that the risk that avian influenza viruses will adapt better to humans is increasing, Poultry World reports.
According to a joint advisory report by the European Centre for Disease Prevention and Control (ECDC) and the European Food Safety Authority (EFSA), the rapid detection of genetic changes in bird flu viruses and rapid sharing of data are “essential”.
The virus cannot yet be transmitted from human to human. However, health experts have long pointed out that this could change in the near future. ECDC and EFSA have advised governments to make plans now, in case this should happen. Further mutations of the virus must also be closely monitored.
Avian influenza is no longer limited to birds alone.
“The list of mammals that have contracted the virus is now long and also includes pets and farm animals,” Poultry World said.
“In European countries, the virus has been found in cats, dogs, mink, foxes and raccoon dogs, while in the US, dairy cows, goats and alpacas have also confirmed to have been infected.”
Another risk is that bird flu viruses mix with other viruses.
“According to scientists, risks also increase if people and animals come into contact with each other more often. This can happen, for example, in intensive livestock farming, but deforestation, urbanisation and global trade also increase the chance that the virus could one day become a major problem for humanity,” the journal reported.
