It’s been a slow flu season this year—until now. In the last week I’ve seen people dragging themselves into the office looking like absolute hell—fevers, cough, severe muscle aches—in other words, they’ve got the flu.
The latest CDC data shows a marked increase in flu activity.
A large percentage of isolates are influenza A, type H1N1, which is currently resistant to one of our antiviral medications oseltamivir (Tamiflu). Of 110 influenza isolates collected so far in Michigan this season, 74 are A(H1N1). The strain is still susceptible to zanamivir (Relenza), rimantadine, and amantadine. Flu A (H1N1) isn’t any nastier than any other strain of flu, but knowing the resistance pattern is important when planning treatment.
So, ladies and gents in the medical field, it’s time to strap in and get ready. It’s only going to get nastier from here. And it’s not to late to vaccinate.
