A recent study may explain why so few humans have become infected, when compared to birds. The H5N1 virus needs to get deep down into the lungs in order to make the human ill. For a human to become infected he/she needs to be in constant contact with sick birds so that a cluster of viruses can build up. Even when a human does get ill, the infection is so deep within the lungs that hardly any viruses are expelled when the patient coughs - making it much harder to infect other humans.


Hundreds of millions of birds have died of H5N1 infection since 2003.
