How is it different from avian (bird) flu?
Avian flu so far has had difficulty infecting humans unless they are exposed intensely to birds, because the virus has not mutated in a way that makes it transmissible by humans to other humans. This virus has origins genetically from both pigs and birds, and the big difference from the avian flu is that this swine virus can be transmitted readily from human to human. 9. What if I’m on a plane? Should I wear a mask? Not necessary. The air on a plane is filtered. Transmission might occur if someone sitting close to you coughs or sneezes on you. The newer designs of aircraft airflow keep the air in a top-down flow, not forced air from front to back. However, if you do have a respiratory illness, it might be best not to travel. 10. Other than hand washing and covering my mouth if I sneeze or cough, what can I do to take care of myself and others? If you are ill, stay home. Control your sneezes and coughs. If you cough into your hand, remember the virus could be live on your hand at least
