To counter this public health issue, the federal
government works closely
with state, local, tribal, and territorial partners, as well as public health
agencies. The approach to
public health is multi-layered, with the goal of
identifying and mitigating introductions of this virus in the United States to
reduce the spread and effects of this virus. On 7 January 2020, CDC
developed a Covid-19 Incident Management Program.
CDC activated its
Emergency Operations Center on January 21, 2020 to help provide continued
support for the Covid-19 response.
CDC released revised health advice for China on January 27, 2020,
recommending that travelers avoid all non-essential travel to all of the
country (Level 3 Health Notice).
The U.S. government has taken unprecedented travel measures in response to
the growing threat posed by this emerging corona virus to public health:
effective February 2, 2020 at 5 pm, the U.S. government has prohibited the
entry of foreign nationals who have been in China for the past 14 days.
U.S. citizens, visitors and their immediate family members who have been to
Hubei Province and other areas of mainland China are permitted to enter the
U.S., but are subject to health monitoring and potential quarantine for up to
14 days. On 1 February 2020, the CDC released
an interim Health Alert
Network (HAN) update to notify state and local health departments and
health professionals about this outbreak.
On January 30th, 2020, CDC released guidelines on the clinical care of
Covid-19 patients for health care professionals. CDC released guidelines on
February 3, 2020 to determine the potential risk
for different exposures to
Covid-19 and to treat those people appropriately.
CDC has sent multidisciplinary teams to Oregon, Illinois, California, Arizona
and Wisconsin to support hospital care, information finding,
and outreach
divisions of safety. CDC developed a real-time Reverse Transcription-
Polymerase Chain Reaction (rRT-PCR) test that can diagnose Covid-19 from
clinical specimens in both respiratory and serum samples. CDC publicly
posted the assay protocol for that study on January 24, 2020. The CDC sent
to the United States an Emergency Use Authorization (EUA) kit,
food and
Drugs Administration for their check on 3 February 2020. On 4 February
2020 the FDA approved the EUA. On February 5, 2020, CDC test kits were
available to order through the agency's International Reagent Service
External symbol from domestic and international partners. When sequencing
was done, CDC submitted the entire genome
of the viruses from reported
cases in the United States to GenBank. CDC has developed the Covid-19
virus in cell culture that is required for additional studies, including further
genetic characterization. The cell-grown virus has been sent to the NIH BEI
Tool symbol for the large scientific community to use.
