CDC Says Recovered COVID-19 Patients Are Protected for up to Three Months; Study: Intense Workouts Heighten Risk for COVID
By Washington Examiner. . .The updated guidance states, “People who have tested positive for COVID-19 do not need to quarantine or get tested again for up to three months as long as they do not develop symptoms again.” It’s the first acknowledgment from the agency that infected people may gain immunity for a period of time.
It is unclear what the CDC based that recommendation on. Only two studies have examined the duration of immunity for people who have recovered from a coronavirus infection. One study, published in Nature Medicine, examined 37 asymptomatic and 37 symptomatic patients in China and found that “antibodies in a high proportion of individuals who recovered from [the coronavirus] infection start to decrease within 2–3 months after infection.” (Read more from “CDC Says Recovered COVID-19 Patients Are Protected for up to Three Months” HERE)

Intense Workouts Can Stress Immune System, Heighten Risk of Respiratory Illnesses, Coronavirus: Study
By Fox News. Extreme exercise routines like marathon running, Crossfit and working out to exhaustion could make some individuals more vulnerable to contracting COVID-19, new research suggests.
Doctors at the American College of Sports Medicine say that some high-intensity forms of fitness can increase a person’s risk of developing the new coronavirus because of increased stress to the immune system that makes it harder to fight off viruses for a short period of time.
“This may not be the time to train for peak performance,” doctors note in the August edition of ACSM’s “Current Sports Medicine Reports,” explaining that this is highly important for those with a heightened risk for coronavirus, who should “refrain from exhaustive exercise,” unusually high exercise workloads” and “overtraining.”
After a high-intensity workout like long-distance running or heavy lifting, ACSM Dr. Thomas Best, a team physician at the University of Miami, tells Fox News the immune system becomes suppressed for a couple of weeks following the exhaustive spurt of exercise, which can increase the risk for viral illnesses like COVID-19.
“High intensity can have short-term detrimental effects — more specific is COVID-19, and the risks to the cardiovascular system,” Best said. (Read more from “Intense Workouts Can Stress Immune System, Heighten Risk of Respiratory Illnesses, Coronavirus: Study” HERE)
