A Christmas Message

Happy Advent and Merry Christmas!

We have had lots of interesting blog posts lately! Here is a review of a few of the topics over the last week and a preview of what’s coming up in the next few days:

Some of the topics in the last week …

- NH and Cheshire County covid rates remain scary high (Dec. 8). It’s astonishing to me that the positivity rate is around 20%. So when you’re waiting in the line of cars for your PCR test at the hospital, there will be someone with covid-19 in one out of every five cars! Remember that earlier in the pandemic, they always wanted the positivity rate to be 5% or below?

- Important background info to our reports (Dec. 9). The full WHO recommendations including their fresh air ventilation rate. Our complete guide to HEPA air purifiers which remove the virus from the room air. And full info on the BinaxNOW home test including false negatives and positives.

- A current list of covid-19 symptoms to watch for (Dec. 11). It’s no longer simple, looking for a cough or sore throat or fever as the leading symptom. It could be a headache, or a feeling of unusual fatigue. When in doubt, test!

And in the days ahead …

- New tips for gathering 100% safely for the holidays.

- A research study that found that more than half of the covid-19 cases in the test cities were linked to inside dining in restaurants. Published Dec. 6th, this has received little play in the national news.

- Due to our first-in-the-nation level of covid-19 virus in our community, we have revised our company policy on covid-19 safety, and we’ll share this with you.

9 Omicron COVID-19 Symptoms Infectious Disease Experts Say You Shouldn't Ignore - Good Housekeeping

by Zee Krstic - December 11, 2021

The most common symptoms for COVID-19 infections, including those caused by Omicron, as listed by CDC officials are below:

  • Fever or body chills

  • Cough

  • Sore throat

  • Shortness of breath or difficulty breathing

  • Fatigue, or muscle or body aches

  • Headache

  • Congestion or runny nose

  • Nausea or vomiting

  • Diarrhea

Any of these symptoms — in any order — may appear within 2 to 14 days after being exposed to SARS-CoV-2. They may be all equally severe or present different severities depending on the symptom.

Simple Air Filtration of Virus

HEPA filters, such as the ones in air purifiers, are 99% efficient at removing virus particles from the air. However, such filters cannot simply replace the one-inch filters you may have in your furnaces or other fan-forced heating units. Reason? They are TOO good, have TOO much resistance to the flow of air, and will mess up your heating unit, possibly making it hazardous.

The safe and partly-effective thing to do is to replace your standard one- or two-inch filter with a "MERV-13” filter. Just slide out the old one, slide in the new MERV-13 filter, and you will get around 40% efficiency at virus removal - and only a little extra pressure drop, so that your unit will probably work just fine. They’re also great for wood smoke and air contaminants from pets and other sources. Just remember that you will need to replace a MERV-13 filter more often than you are used to, something like twice as often.

MERV-13 filters became instantly popular last year in the early months of the pandemic, and were completely sold out for quite a while. Now they are readily available, if not at your local hardware store, then from many online sources.

They’ve Had to Make the Graph Taller

It appears that Covid ActNow’s site expanded their graph to show Cheshire County’s spike in Covid-19 confirmed cases — see the graph below.

Apparently the cases for testing in Cheshire County are way up also; Roy reports that the Keene Hospital has doubled up their PCR testing line, now doing two cars at a time. There was still a fairly long line for his PCR test yesterday.
