Analyzing a Chinese restaurant in which a super-spreader event occurred, a UC-Santa Barbara mathematician calculates that it would be necessary to have more than 50 air changes an hour rather than the current 10 to prevent an accumulation of a CoVid-infected cloud in an indoor space. That would feel like a brisk breezing blowing through the restaurant.  Furthermore, the residual air in the space would require far more rigorous filtration with MERV-13 or better HEPA filters.

A single CoVid infected diner can generate a dangerously-contaminated aerosol/droplet cloud in a matter of minutes.  Indoor dining is categorically unsafe, and safe. outdoor dining requires lots of spacing and a stiff wind.

Markedly obese CoVid patients are nearly 3 times more likely than those with normal body masses to require ICU admission, go on a ventilator, or die.  An international collaborative team just published these results from their meta-analysis of 335,192 patients treated over the past 11 months.

The investigators suggest 3 explanations for this effect.  First of all,  excess body weight negatively alters a patient’s respiratory mechanics exacerbating the impact of viral lung damage.  Secondly, the additional body fat may serve as a CoVid reservoir as it does for other common human viruses.  Finally, obesity may drive underlying low-grade inflammation and immune suppression.

The severely obese must avoid contracting CoVid at all costs.

More than three-quarters of adults who recovered from CoVid have imaging evidence of significant cardiac damage.   German investigators report this conclusion after studying 100 men and women with an average age of 49.

Each patient underwent cardiac MRI imaging an average of 71 days following their CoVid diagnosis.  At that time, 76% of the group had elevated troponin levels indicative of cardiac muscle damage.  The CoVid group compared with healthy controls demonstrated diminished cardiac function.

If you’ve had CoVid, don’t return to active exercise for 3 weeks after recovery.  For extra safety, particularly if you were hospitalized for CoVid, undergo a thorough cardiac examination looking for myocarditis or cardiac inflammation.

Fifty percent of college students suffer long-term effects from CoVid, and that counters the myth that young adults are largely unaffected by the virus.  Researchers at the University of Dayton and NY’s Mt. Sinai School of Medicine compared 43 CoVid positive university students with 58 healthy controls.  

The half suffering continuing CoVid were 43% more likely to have lifestyle-limiting exercise intolerance and shortness of breath, 24% more like to experience chest pain, 36% more likely to have appetite loss, and 19% more likely to have continuing taste and smell problems.

CoVid is a nasty disease even for the young.  Avoid contracting it by masking, distancing, and washing.
