From your article: “The highly contagious Omicron variant has thrown us a curve ball,” said DHW Director Jeppesen. “Once again, the situation in our hospitals and health systems is dire – we don’t have enough resources to adequately treat patients. Please get vaccinated and boosted if you can and wear a high-quality protective mask in public places. Omicron is so much more contagious than previous variants, and even though a lower percentage of cases are ending up in the hospital, the record number of cases is still putting strain on our healthcare system.”
From Jan 2022. Most effective vaccine ever.
