Various Olympics flights will run between the U.S. and Beijing between now and then. Williamson, a 25-year-old first-time Olympian, said he was hoping to catch one of them. He said he first tested positive this past Sunday, meaning he'll likely clear his infection well before the two-man and four-man bobsled competitions, which begin Feb. 14 and 19, respectively.
Olympic rules, however, present extra hurdles. Williamson — like every other member of the delegation who has tested positive this month — will need four consecutive days of negative tests, plus a fifth-day buffer, before he can depart, according to updated protocols finalized late last week.
Each of the four tests must be a PCR test, which can remain positive for weeks after a person clears the contagious phase of their infection.
