🧵One thing I’ll always remember from when mask mandates were dropped is how gleefully my colleagues at the time rushed back to normal.
I begged them to consider what it meant for high risk folks like me.

My latest @cidrap.bsky.social op-ed: The mRNA COVID vaccine myocarditis signal was real. The system caught it. Since 2022, no updated formulation has triggered a significant myocarditis signal.

Reinfections aren't harmless "boosters", they stack the deck against your HEART, turning one hit into compounding long-term cardiovascular risks. ➡️3 important and recent articles (from 2025–2026) providing the strong evidence that SARS-CoV-2 reinfections increase risks of long COVID, including cardiovascular complications like myocarditis, arrhythmias, heart disease, thromboembolism, and related issues( There're more!!):

Covid is oncogenic, increases your chance of heart disease & stroke, seriously weakens your immune system, can bring on POTS, MCAS, ME, diabetes & myriad other disabling chronic illnesses but folks trying to protect themselves are ‘overreacting’
Cool, cool, cool.

Graphic from The Sick Times sharing the latest COVID-19 trends for March 3, 2026. The graphic presents trends for three metrics: WastewaterSCAN category for SARS-CoV-2, which is “high” (represented with an orange color) and stable (represented with a side to side arrow); CDC wastewater viral activity level for SARS-Cov-2, which is “moderate*” (orange) and slightly decreasing (represented with a diagonal down arrow); and CDC COVID-19 test positivity, which is moderate (darker yellow) and slightly decreasing. Text below these metrics reads: “*CDC wastewater viral activity levels are calculated based on measurements in the last two years only. They do not account for the lower spread that could be possible with more widespread precautions.”
The COVID-19 picture in the U.S. hasn’t changed much over the last month: national disease levels are declining, but very slowly, as some parts of the country remain disease hotspots even as we head into the spring. Flu is similarly still at high levels. bit.ly/4sktidd

Long COVID isn’t rare.
According to the WHO, about 15 in 100 people still have symptoms 12 months after COVID-19 infection.

Prevent Birth Defects . Take Folic Acid. It’s important to get enough folic acid daily, starting at least one month before becoming pregnant and continuing throughout the pregnancy, to prevent serious birth defects in the baby’s brain and spine. Some foods have folic acid, but the simplest way to make sure you get enough is to take a vitamin that has folic acid every day. Talk to your doctor to find the right vitamins for you.
Prevent Birth Defects Stay up to date on vaccines. Having certain illnesses during pregnancy can affect your baby and cause serious birth defects or increase their risk of illnesses when they are born. Be sure you are up to date on your vaccinations if you plan to be pregnant. Some vaccines can be given during pregancy, but some cannot, so it’s important to talk to your doctor about vaccination before getting pregnant and throughout your pregnancy.
Avoid smoking, vaping, drugs, and alcohol , Harmful habits like smoking, vaping, drinking, and using drugs can cause your baby serious birth defects and hurt their development. It’s important to completely remove these substances during pregnancy. If you are experiencing pain and need resources for pain management, talk to your doctor about safe options.
Maintain a healthy weight. Being underweight or overweight increases the risk of birth defects and pregnancy complications. Maintain a healthy weight before getting pregnant with good nutrition and regular exercise. Always talk to your doctor to be sure you are eating well and getting safe levels of activity during your pregnancy.
Today is World Birth Defects Day. Protecting your child’s lifelong health starts with the choices you make for a healthy pregnancy and birth. Learn more about steps you should take before and during pregnancy to set your child up for a healthy life: www.healthychildren.org/English/ages...

An article came out recently that looked at the effect of CO2 on influenza decay in sessile saliva droplets. The study confirms what we have been saying since 2022: respiratory fluids become highly alkaline when they leave the body, and this in turn affects microbe viability <partial screenshot of the article's webpage> Given that this is a research area where our team has made a lot of waves, I thought I should share my thoughts.

Increased incidence of mild cognitive impairment in long COVID patients 🚨One viral infection →Long COVID→ quadrupled the risk of Alzheimer's-like brain decline!😧 ➡️In this USA blinded observational cohort study of 260 adults, participants were classified as Long-COVID, recovered COVID-positive (no persisting symptoms), or COVID-negative controls and followed for a mean of 4.4 years using rigorous NACC/NIA-AA criteria for mild cognitive impairment(MCI) and dementia. ➡️Cumulative MCI incidence was dramatically higher in Long-COVID patients (27%) versus recovered-COVID (5%) or COVID-negative (1%) groups.

The Public & many healthcare staff were led to believe that FRSM surgical masks worked but they are inadequate for an airborne infection because they have gaps, they do not seal to the face. The evidence in the covid inquiry shows that they knew covid was airborne from the outset.

Reduce possible harm by avoiding infection and reinfection — preventing COVID is possible through measures such as masking, ventilation, testing and vaccination.

COVID is not “just a cold.” Even mild or asymptomatic infections can cause lasting health effects, damaging blood vessels and organs, affecting the brain, and weakening the immune system.

She's got a little art deco backpack!
These snails live in shallow waters at locations around the world (Hawaii, South Africa, Japan).
