Before the latest flu season had officially gotten under way, the swine flu (or H1N1 virus) was already stealing headlines as it left a trail of fever, aches, and general misery across the country. For people with asthma, watching the swine flu sweep across the nation has been especially nerve wracking. Both swine flu and asthma attack the airways, and having both conditions makes people particularly vulnerable to severe respiratory complications from swine flu. "Patients with asthma are more likely to develop lower respiratory infections, including pneumonia, as well as asthma exacerbations," says James Li, MD, PhD, FAAAAI, professor of medicine and chairman of the allergy and immunology division at the Mayo Clinic.
When Jack McNeill, an 18-year-old freshman at Vanderbilt University, developed symptoms of the 2009 H1N1 swine flu in September, his condition quickly deteriorated. "I went to bed on a Tuesday night feeling fine. I woke up the next morning and felt terrible," he recalls. "I was dizzy, weak, feverish, and simply in a fog." After a doctor at the student health center put him on Tamiflu he started feeling better, but within a couple of days he had begun coughing so severely that he was bringing up blood. "I could not do anything remotely active without beginning to wheeze," he says. "My chest was very tight and I had trouble taking in big breaths."
An icky fact: That elevator button or door knob you just touched? It likely has flu germs on it. If you're avoiding the flu, take note. Then wash those hands. Do it the right way -- and do it often, several times a day!
It's true -- germs can live on any surface for two hours or more. If someone in your office or school is infected, those germs can reside on anything they've touched -- desks, phones, coffee pots, microwaves, cafeteria tables, toys, books.
When flu prevention experts advise you...
Taking a combination of antiviral and asthma medications finally eased McNeill's symptoms, but not all asthma patients with H1N1 swine flu are so fortunate. In fact, research has found that asthma is the leading underlying medical condition found among H1N1 patients requiring hospitalization. Nearly 30% of both child and adult patients hospitalized for swine flu have asthma.
If you have asthma, there are steps you can take to avoid getting H1N1, and tips to follow if you do develop symptoms of swine flu.
