Dödligt virus från Kina orsakar panik (SARS-CoV-2, COVID-19)

United States
The US CDC initially declined to test the patient who on Feb. 26 become the latest confirmed case in the US, and the first with an unknown origin of infection (raising the concern that there are more cases circulating among the general public that have not been identified).

The patient, who was on a ventilator with a suspected viral infection, was transferred from another hospital to UC Davis Medical Center on Feb. 19. The hospital's request to test for COVID-19 was initially denied by CDC, as the patient did not meet the COVID-19 testing criteria (had not recently traveled to countries with outbreaks or been in contact with someone with the virus). The CDC on Feb. 27 issued new testing rules, for which many more people can now be tested for the coronavirus.

Just 12 of more than 100 public health labs in the U.S. are currently able to test for COVID-19 because of a problem with the test developed by CDC. The agency can now screen only 350-500 samples per day. California Governor Gavin Newsom characterized the number of test kits available in the state as “remarkably inadequate.”

As of Feb. 26, CDC had performed a total of 445 tests. For comparison, the UK, with a population five times smaller than the US, had conducted over 7,000 tests.
