3 COVID Experts on Why the CDC's Isolation Guidelines Are Bad for Public Health
"...these bare-bones isolation guidelines will likely make more people sick -- and that this approach increasingly places the burden of public health on individual people, which is dangerous for everyone, but especially for those at a higher risk of complications from the virus."

"the findings can be regarded as a warning for the risk of developing long-term neurological complications, even after an asymptomatic infection or mild disease process."

CDC Drops Five Day Covid-19 Isolation Despite Controversy
"People can't judge whether they are infectious or not. Fever is not a good barometer for Covid-19. While most transmission occurs early in the illness, 20 to 40% of people can still transmit COVID after five days, and some even longer."

"For example, what if SARS-CoV-2 infection causes the immune system to be able to respond to SARS-CoV-2 in such a way that we no longer experience severe COVID infections, but rather it causes a subtler, long-term immunological changes that leave us more vulnerable to other infections or even chronic disease?"

Top COVID-19 and long COVID researcher Dr. Ziyad Al-Aly, Chief of Research and Development, VA St. Louis Health Care System and Clinical Epidemiologist at Washington University in St. Louis:
Mounting research shows that COVID-19 leaves its mark on the brain, including with significant drops in IQ scores
"DCE-MRI imaging revealed significantly increased whole-brain leakage in patients with long COVID with brain fog, with an increased percentage of brain volume with leaky blood vessels in the cohort with brain fog compared to the cohort without brain fog."

"...these findings suggest that SARS-CoV-2 infection damages the CD8+ T cell response, an effect akin to that observed in earlier studies showing long-term damage to the immune system after infection with viruses such as hepatitis C or HIV. The new findings highlight the need to develop vaccination strategies to specifically boost antiviral CD8+ T cell responses in people previously infected with SARS-CoV-2, the researchers conclude."

"Doctors say there's evidence that repeat Covid infections could increase your risk for many other health problems, including diabetes, heart conditions, gastrointestinal diseases, and long Covid."

"Each infection is like taking a chance at the lottery," Dr. Friedberg says. "The odds are a bit better than they were three years ago, but there is still a chance you could end up with serious illness, permanently disabling changes in your ability to think, breathe, or move, or die from this disease."

Heart Problems After Covid
"Does COVID-19 cause heart problems? Yes. A severe or even mild case of COVID-19 can make you more likely to have heart failure or a heart attack." (emphasis mine)
