China has made COVID-19 anal swab tests mandatory for nearly all international arrivals despite complaints that the procedure is humiliating.
The tests will be required for all travelers arriving at Beijing and Shanghai airports before they are allowed to enter the country.
Despite the degrading nature of the procedure, Chinese health authorities claim it is more effective at identifying COVID-19 than nasal swabs.
"The same procedure applies to visitors who came from countries where COVID-19 cases are high or they tested positive upon arrival," reports IB Times. "If a person shows symptoms of diarrhea, he or she must also get an anal swab."
