Their data so far suggest that a lot of people have had Covid-19 without ever receiving a diagnosis. Confirmed case counts suggest that almost 7 percent of people in the U.S. have had the virus. Data from the arm of the study looking at blood from clinical laboratory tests from all 50 states, the District of Columbia, and Puerto Rico found rates of antibody positivity that at times ranged from under 1 percent in some states to 23 percent in New York.

“The prevalence of celiac disease is low in an urban, predominately male, African-American population with iron deficiency. Routine small intestinal biopsy for celiac disease in similar populations should not be done. EGD remains clinically important.”

The evidence derived from these limited studies suggests that 2000 mcg doses of oral vitamin B12 daily and 1000 mcg doses initially daily and thereafter weekly and then monthly may be as effective as intramuscular administration in obtaining short term haematological and neurological responses in vitamin B12 deficient patients.

No mention of whether or how a dried virus could infect anyone yet.

Coeliac patients have an increased risk of developing cancer in relation to the age of diagnosis of CD. This risk results higher for malignancies of the gastro-intestinal sites. An accurate screening for tumors should be performed in patients diagnosed with CD in adulthood and in advancing age.

The [rapid] test can detect more than 80 percent of infections found by the lab-based P.C.R. test. But when used to screen asymptomatic people, it detected only 32 percent of the positive cases identified by the P.C.R. test.

In April, as coronavirus cases multiplied across the country, the head of the U.S. Environmental Protection Agency rejected scientists’ advice to tighten air pollution standards for particulate matter, or soot.

In the next few weeks, EPA Administrator Andrew Wheeler likely will reaffirm that decision with a final ruling, despite emerging evidence that links particulate pollution to COVID-19 deaths.

There was enough evidence to support a stricter standard before the pandemic, said Christopher Frey, an environmental engineering professor at North Carolina State University who studies air pollution. The added threat from the coronavirus is like “icing on the cake,” he said, and should compel Wheeler to adopt an even more stringent limit.

Particulate matter kills people. “It is responsible for more deaths and sickness than any other air pollutant in the world,” said Gretchen Goldman, a research director at the Union of Concerned Scientists.
