SUNDAY, July 21, 2024 (HealthDay News) -- As yet another batch of variants fuel a COVID surge this summer, one expert offers advice on how to navigate the threat.

While some of that is due to how the COVID virus spread, human behavior is also at play, he added. If you aren't spared during this summer surge, what can you expect with the new variants? Luckily, available testing still detects the FLiRT variants, while Paxlovid is still widely available and works very well, he said.
