Study Shows Virus Capability to Spread Through Airborne Exposure
In a recent study done by researchers at the University of Hong Kong said that the H7N9 bird flu virus has the capability of spreading from human to human. The capability of spreading is not limited through direct contact but through airborne exposure as well.
The study was done using ferrets an animal used for research into the effects of the human influenza, have placed a ferret injected with the virus to close proximity with others in different cages became infected through airborne transmission. Although the World Health Organization said that there is still no evidence of sustaining human to human transmission. The study merely suggests the possibility of the virus evolving further and is forming a basis of a pandemic threat that cannot be excluded.
The research team also discovered that the ferrets infected did not show any signs of fever or a clinical sign that indicates asymptomatic infections in humans is possible. Thus making it harder for them to detect and control the virus. The research also showed that the virus can infect pigs but can’t be transmitted from pig to pig or from a pig to other animals.
The virus have already infected 130 people in China have died or became very ill were triggered by other causes and there are no new cases of infection this month.
