Is H5N1 a coronavirus?

A (H5N1) and severe acute respiratory syndrome (SARS) coronavirus are infections that cause a severe viral pneumonia leading to acute respiratory dysfunction syndrome and carry a high case-fatality rate.
Can you get bird flu from eating chicken?
You cannot get bird flu from eating fully cooked chicken , turkey, or duck, because heat kills the virus. In a few cases, bird flu was passed from one person to another person, not from a bird to a person. But this was very rare.
Should we worry about bird flu?

Is there a vaccine for bird flu?
While avian flu vaccines are currently available , they are not being used on a large scale on poultry farms because this hinders the ability to conduct surveillance testing, which helps detect the virus in unvaccinated flocks and limit the spread of the disease.
Is bird flu an airborne disease?
airborne transmission
of bird flu from wild birds to poultry is negligible , says new research. New research from Wageningen Bioveterinary Research (WBVR) has demonstrated that the risk of airborne transmission of the hi-path avian influenza virus from infected wild waterfowl to poultry is negligible.
Is bird flu transmitted human to human?
Transmission from birds to humans is infrequent and no sustained human-to-human transmission has been observed , however it can cause severe disease in humans. The A(H5N1) virus has only sporadically been detected in European poultry or wild birds.

What’s the Ebola death rate?
The virus is transmitted to people from wild animals and spreads in the human population through human-to-human transmission. The average EVD case fatality rate is around 50% Case fatality rates have varied from 25% to 90% in past outbreaks. Community engagement is key to successfully controlling outbreaks.
Why has the bird flu not become a pandemic?
The viruses occasionally infect humans and the H5N1 strain has infected more than 400 people since 2003. H5N1 has a high mortality rate in humans, at around 60 per cent, but to date there has been no sustained human to human transmission of the virus , which would need to happen in order for a pandemic to occur.
