Be Wary of a Brutal Flu Season: Brainstorm Health

Hello and happy hump day, readers.

The leaves are turning, the chill is coming, and, sure enough, the influenza virus is plotting its annual attack.

Flu season is a simple matter of life. It’s also a notoriously difficult-to-predict public health nuisance once the seasons turn. But the (very) early indications suggest the coming onslaught could prove… Unpleasant.

Again, this is all guesswork (perhaps the most infuriating part of fighting the flu, which has multiple, ever-shifting pathogenic avatars). But there are some initial concerns based on the nasty flu season our Australian friends in the Southern Hemisphere, who grapple with flu season about six months earlier than us Northerners, experienced recently.

Of particular concern is that the deadly H3N2 flu virus variant, which led to one of the deadliest flu seasons in America between 2017 and 2018, was the driving factor in Australia’s cases. Things could turn out differently in the U.S., but it’s still cause for concern, according to some public health officials.

There are a few ways to combat the flu. Wash your hands. Stay away from people who seem sick (and don’t go into work if you’re sick yourself). And, most importantly… Get your flu shot.

The virus’ very nature makes it difficult to construct an effective vaccine since they have to be created in bulk before experts even know which strain is most problematic—but public health officials consistently agree it’s the most effective way to protect both yourself and others from a nasty, and potentially deadly, illness.

DIGITAL HEALTH

Amazon just made another health care move. Amazon's slow-drip foray into health care continued this week as the tech giant announced a deal to acquire Health Navigator, a telemedicine company, for an undisclosed sum. This builds on the initial acquisition that sent legacy medical firms into a tizzy (of the online pharmacy firm PillPack) back in 2018; but there's still an open question on just how involved Amazon wants to get into such a highly complicated, regulated, and all-around messy market. It could very well prove a dominant player on the fringes—but is the firm willing to get into the deeper trenches of the U.S. health arena? (MarketWatch)

INDICATIONS

Eli Lilly shares drop on disappointing diabetes sales. Shares of U.S. drug giant Eli Lilly slipped nearly 2.5% in Wednesday trading after sales of its diabetes drug Trulicity missed Wall Street expectations. The diabetes space is tough and filled with plenty of competitors—and Trulicity sales actually did climb considerably, but just not as much as analysts had predicted. One theory is that a competitive pricing environment in a crowded field may brought down Lilly's numbers. (Reuters)
