How serious is H1N1 flu infection?
Like seasonal flu, H1N1 flu in humans can vary in severity from mild to severe. Most people who have had the H1N1 virus have done well, but a small number of patients have been seriously ill, and some have died. The most serious cases have generally appeared in patients who have had underlying medical conditions which predisposed them to more complications such as pneumonia, secondary bacterial infections, asthma attacks, etc. Conditions that may put you at high risk include, but are not limited to, asthma, diabetes, or other conditions affecting the heart, lungs, blood, liver or kidneys, weakened immune system. Women who are or may be pregnant are also at a higher risk of complications from H1N1.
