    Covid Timeline

  • WHO Country Office in China is informed

    The World Health Organization (WHO) Country Office in China is informed of several cases of a pneumonia of unknown etiology (cause) with symptoms including shortness of breath and fever occurring in Wuhan, China. All initial cases seem connected to the Huanan Seafood Wholesale Market.
  • Wuhan Lockdown & US State of Emergency

    A scientist in China confirms that a mysterious new pneumonia-like illness identified in Wuhan, China, in December 2019, can be transmitted from human to human. Two days later, China puts Wuhan under strict lockdown. Meanwhile, on the other side of the globe, the U.S. sees its first case of the disease, later named COVID-19. The patient is a resident of Washington state who had traveled to Wuhan. The Trump Administration declares a public health emergency.
  • Travel Restrictions

    Cases of COVID-19 begin to multiply around the world. Countries are restricting travel to contain the virus.
  • Pandemic

    The WHO characterizes COVID-19 as a pandemic. In the U.S., the Grand Princess cruise ship is held at sea off the coast of California after 21 of the 3,500 people aboard test positive for the virus. California also becomes the first state to order all residents to stay home with the exceptions of going to an essential job or shopping for essential needs. Hospitals become overwhelmed, and there is a nationwide shortage of personal protective equipment (PPE).
  • Sealed Borders, masking, social distancing

    As cases continue to surge, countries keep their borders sealed. Businesses shut down (leading to massive job losses), schools close, sporting events cancel, and college students go home. People start wearing masks and practicing “social distancing.”
  • Flattening the Curve

    After months in lockdown, states slowly begin a “phased reopening,” based on criteria outlined by the Trump Administration, in coordination with state, county, and local officials. Meanwhile, scientists across the globe are in a race to understand the disease, find treatments and solutions, and develop vaccines.
  • Reinfection and High Mortality

    The first documented case of reinfection is reported in Hong Kong. On a broader scale, COVID-19 is now the third leading cause of death in the U.S. (after heart disease and cancer).
  • FDA approves Remdesivir

    The Food and Drug Administration (FDA) grants full approval to a drug called remdesivir for treatment of COVID-19
  • Early Vaccines

    The FDA grants Pfizer-BioNTech the first Emergency Use Authorization (EUA) for an mRNA vaccine, a new type of vaccine that has proven to be highly effective against COVID-19. A week later, it grants another EUA to Moderna, also for an mRNA vaccine.
  • Supply and Demand

    Around the world, the race is on to vaccinate as many people as possible in time to slow the spread of the variants. Researchers work to understand how deadly or contagious variants are compared to the original virus.
  • Global Death Toll

    2 Million People
  • Global Cases

    100 Million
  • Variants

    There is not enough vaccine supply to meet the demand. But the Biden Administration expects the addition of a third option (by Johnson & Johnson) to make vaccines more available to everyone. Meanwhile, companies are working to tweak their products to make distribution easier and to control new variants.
  • US Death Toll

    U.S. COVID-19 related deaths surpass 500K.
  • Vaccine Funds

    Biden administration announces $10B investment to expand access to COVID-19 vaccines and build vaccine confidence in hardest-hit and highest-risk communities.
  • Global Deaths

    Global COVID-19 related deaths surpass 3M.
  • Masking Guidelines

    Centers for Disease Control and Prevention updates outdoors face mask guidance for fully vaccinated people.
  • Masking Indoors

    Deputy Secretary of Defense issues guidance which removes requirements for mask wearing for fully vaccinated personnel, indoors and outdoors, at DOD facilities. The DOD guidance remains consistent with the Centers for Disease Control and Prevention guidance about mask wearing for unvaccinated or partially vaccinated personnel, and where local jurisdictions require masks.
  • US Deaths

    U.S. COVID-19 related deaths surpass 600K.
  • Global Deaths

    Global COVID-19 related deaths surpass 4M.
  • Global Deaths

    Global COVID-19 related deaths surpass 5M.
  • Home Testing

    DOD, in coordination with the Department of Health and Human Services, awards contract modifications to Abbott Rapid Dx North America, LLC, and iHealth Labs Inc. to purchase COVID-19 antigen over-the-counter tests in support of POTUS' 1B free at-home COVID-19 tests.
  • US Deaths

    U.S. COVID-19 related deaths surpass 1M; POTUS issues a proclamation directing that the U.S. flag be flown at half-staff.
  • Children Vaccines

    Food and Drug Administration expands eligibility for Pfizer-BioNTech COVID-19 vaccine booster dose to children 5 through 11 years.
  • End of Pandemic

    Public Health Emergency for COVID-19, declared under Section 319 of the Public Health Service Act, expires at the end of this day
