Yes. Clients are reporting complaints up by 50% or more in the past month. While some reports of illness align with community or businesses associated with higher Noro activity, most don’t. There are a lot of single illness reports or single large parties where one of the guests may have arrived already ill and passed it on. Across our client base, without any specific geographic focus, there is much more complaint activity than there has been in the last two years. We will continue to monitor this and report trends.
Its genetic mutations make it hard to distinguish from the Delta variant using PCR tests, compared to the original version of Omicron, which was very easy to test for because of certain genetic markers. BA.2 does seem more transmissible than the original BA.1 Omicron variant, and it already accounts for a large percentage of new infections in the US. The talk of it being stealth really just implies that it’s a bit harder to identify through variant testing. Considering it’s already making up nearly three quarters of new cases globally, we’d hardly call it stealth at this point.
This is unfortunately quite common, and there are a few reasons someone might test negative even though they’re actually sick with COVID. First, they might take the test too soon after exposure. It can take a few days after close contact to build enough viral load to test positive. Some people just have low viral load or take longer to build up to a detectable level. Sometimes it’s a collection issue, where the sample just didn’t get enough of the virus because of how it was swabbed. Even the very best PCR tests (which are the gold-standard for COVID testing) still just miss some positive tests, and rapid antigen tests have an even higher false negative rate. For rapid antigen tests, taking two tests 24 hours apart does catch many more cases - up to 94%
Likely, the answer is yes - it went undetected (or misdiagnosed). Masks, social distancing, daily wellness checks and better ventilation did reduce some transmission of TB. However, the WHO believes that a larger number of TB deaths occurred during the first year of the pandemic, in particular, as TB went both undiagnosed and untreated. According to their data, an estimated 10 million people developed TB in 2021 but only 5.8 million were treated. TB’s impact on the workplace has increased over the last decade and we expect it will continue to be one of the more difficult workplace health situations to manage.
