Coronavirus Disease 2019 (COVID-19) Situation Summary

This is an emerging, rapidly evolving situation and CDC will provide updated information as it becomes available, in addition to updated guidance.

Updated February 25, 2020


CDC is responding to an outbreak of respiratory disease caused by a novel (new) coronavirus that was first detected in Wuhan City, Hubei Province, China and which has now been detected in 37 locations internationally, including cases in the United States. The virus has been named “SARS-CoV-2” and the disease it causes has been named “coronavirus disease 2019” (abbreviated “COVID-19”).

On January 30, 2020, the International Health Regulations Emergency Committee of the World Health Organization declared the outbreak a “public health emergency of international concernexternal icon” (PHEIC). On January 31, 2020, Health and Human Services Secretary Alex M. Azar II declared a public health emergency (PHE) for the United States to aid the nation’s healthcare community in responding to COVID-19.

Source and Spread of the Virus

Coronaviruses are a large family of viruses that are common in many different species of animals, including camels, cattle, cats, and bats. Rarely, animal coronaviruses can infect people and then spread between people such as with MERS-CoV, SARS-CoV, and now with this new virus (named SARS-CoV-2).

The SARS-CoV-2 virus is a betacoronavirus, like MERS-CoV and SARS-CoV.  All three of these viruses have their origins in bats. The sequences from U.S. patients are similar to the one that China initially posted, suggesting a likely single, recent emergence of this virus from an animal reservoir.

Early on, many of the patients in the COVID-19 outbreak in Wuhan, China had some link to a large seafood and live animal market, suggesting animal-to-person spread. Later, a growing number of patients reportedly did not have exposure to animal markets, indicating person-to-person spread. Person-to-person spread has been reported outside China, including in the United States and other locations. Chinese officials report that sustained person-to-person spread in the community is occurring in China. In addition, other destinations have apparent community spread, meaning some people have been infected who are not sure how or where they became infected.

Situation in U.S.

Imported cases of COVID-19 in travelers have been detected in the U.S. Person-to-person spread of COVID-19 also has been seen among close contacts of returned travelers from Wuhan, but at this time, this virus is NOT currently spreading in the community in the United States.

Illness Severity

Both MERS-CoV and SARS-CoV have been known to cause severe illness in people. The complete clinical picture with regard to COVID-19 is not fully understood. Reported illnesses have ranged from mild to severe, including illness resulting in death. Learn more about the symptoms associated with COVID-19.

There are ongoing investigations to learn more. This is a rapidly evolving situation and information will be updated as it becomes available.

Risk Assessment

Outbreaks of novel virus infections among people are always of public health concern. The risk from these outbreaks depends on characteristics of the virus, including how well it spreads between people, the severity of resulting illness, and the medical or other measures available to control the impact of the virus (for example, vaccine or treatment medications). The fact that this disease has caused illness, including illness resulting in death, and sustained person-to-person spread is concerning. These factors meet two of the criteria of a pandemic. As community spread is detected in more and more countries, the world moves closer toward meeting the third criteria, worldwide spread of the new virus.

The potential public health threat posed by COVID-19 is high, both globally and to the United States.

But individual risk is dependent on exposure.

  • For the general American public, who are unlikely to be exposed to this virus at this time, the immediate health risk from COVID-19 is considered low.
  • Under current circumstances, certain people will have an increased risk of infection, for example healthcare workers caring for patients with COVID-19 and other close contacts of persons with COVID-19. CDC has developed guidance to help in the risk assessment and management of people with potential exposures to COVID-19.

However, it’s important to note that current global circumstances suggest it is likely that this virus will cause a pandemic. In that case, the risk assessment would be different.

What May Happen

More cases are likely to be identified in the coming days, including more cases in the United States. It’s also likely that person-to-person spread will continue to occur, including in the United States. Widespread transmission of COVID-19 in the United States would translate into large numbers of people needing medical care at the same time. Schools, childcare centers, workplaces, and other places for mass gatherings may experience more absenteeism. Public health and healthcare systems may become overloaded, with elevated rates of hospitalizations and deaths. Other critical infrastructure, such as law enforcement, emergency medical services, and transportation industry may also be affected. Health care providers and hospitals may be overwhelmed. At this time, there is no vaccine to protect against COVID-19 and no medications approved to treat it. Nonpharmaceutical interventions would be the most important response strategy.

CDC Response

Global efforts at this time are focused concurrently on containing spread of this virus and mitigating the impact of this virus. The federal government is working closely with state, local, tribal, and territorial partners, as well as public health partners, to respond to this public health threat. The public health response is multi-layered, with the goal of detecting and minimizing introductions of this virus in the United States so as to reduce the spread and the impact of this virus. CDC is operationalizing all of its pandemic preparedness and response plans, working on multiple fronts to meet these goals, including specific measures to prepare communities to respond local transmission of the virus that causes COVID-19. There is an abundance of pandemic guidance developed in anticipation of an influenza pandemic that is being repurposed and adapted for a COVID-19 pandemic.

Highlights of CDC’s Response

CDC has worked with the Department of State, supporting the safe return of Americans who have been stranded as a result of the ongoing outbreaks of COVID-19 and related travel restrictions. CDC has worked to assess the health of passengers as they return to the United States and provided continued daily monitoring of people who are quarantined.

CDC is shipping the test kits to laboratories CDC has designated as qualified, including U.S. state and local public health laboratories, Department of Defense (DOD) laboratories and select international laboratories. The test kits are bolstering global laboratory capacity for detecting SARS-CoV-2.

  • CDC laboratories have supported the COVID-19 response, including:
    • CDC has developed a real time Reverse Transcription-Polymerase Chain Reaction (rRT-PCR) test that can diagnose COVID-19 in respiratory samples from clinical specimens. On January 24, CDC publicly posted the assay protocol for this test.
    • CDC has been uploading the entire genome of the viruses from reported cases in the United States to GenBank as sequencing was completed.
    • CDC has grown the COVID-19 virus in cell culture, which is necessary for further studies, including for additional genetic characterization. The cell-grown virus was sent to NIH’s BEI Resources Repositoryexternal icon for use by the broad scientific community.

CDC Recommends

  • While the immediate risk of this new virus to the American public is believed to be low at this time, everyone can do their part to help us respond to this emerging public health threat:
    • It’s currently flu and respiratory disease season and CDC recommends getting a flu vaccine, taking everyday preventive actions to help stop the spread of germs, and taking flu antivirals if prescribed.
    • If you are a healthcare provider, be on the look-out for people who recently traveled from China and have fever and respiratory symptoms.
    • If you are a healthcare provider caring for a COVID-19 patient or a public health responder, please take care of yourself and follow recommended infection control procedures.
    • If you have been in China or have been exposed to someone sick with COVID-19 in the last 14 days, you will face some limitations on your movement and activity. Please follow instructions during this time. Your cooperation is integral to the ongoing public health response to try to slow spread of this virus. If you develop COVID-19 symptoms, contact your healthcare provider, and tell them about your symptoms and your travel or exposure to a COVID-19 patient.
    • For people who are ill with COVID-19, please follow CDC guidance on how to reduce the risk of spreading your illness to others.

  1. “Fools rush in, where “Angels” fear to tread”? “Stupidity is highly arrogant and highly critical absent Critical Relevance to Real Issues? “A Hard Head makes a soft ‘Ba- hind”!!!

    LBRC- Chemtrails, MK Ultra, 5G and CERN teaches us?

    “The Government no longer belong to The People! The People belong to The Government”! 

    1. Representatives represent the Lobbyist, not you! You only believe they do because now and then, they’ll send an “Average Activist” an email minus follow- up with respect to results or the initial request! 

    2. For years citizens have been frogs in gradually boiling water! Those outside The Pot are little more than Walking Zombies! Can’t afford a “Free” Clue about the pending  Economic, Political and Social Hurricane on The Horizonl!!!

    3. During a pending Pandemic, what does anybody with a Brain Stem want to avoid? Large Crowds maybe? Had a good time at “The Mardi Gras”? Good News- Few in The Hood migrate outside it! Chances of Travel to China, Japan, South Korea, Italy and yada? What are the chances water doesn’t make wet? Bad News- How many have a clue about how Viruses Spread and The value of impeccable sanitation and Transmission Precautions during a Pandemic? Carona can incubate for an “Entire Month” aka at least 28 Days! Uh oh!!! 

    btw- Did you know there are “Corona Virus Bonds” for sale? (Google it!). What will these Bonds do?

    a. Central Banks will sell the Bonds to their Corporate Buddies short on operational funds due to “The Virus”! Guess who’ll buy back the Bonds, just before their ‘Peeps Default on them? The Central Bank will print in order to “Purchase Back”? Who will be on the hook, just like TARP 2007 and on…? Now say “Joe/Jane 6 Pk aka “you”! 

    b. In 2007, they told you it was a “Corporate” Bail Out (btw- The Bail Out aka “Money Printing” and “Plunge Protection Team” has been ongoing since)! In 2020, because you belong to The Government- They decided “Stupid ain’t worth educating”! This is what we hear!!! 

    To all The “Feel Good” Freaks out there, especially The ‘Stuntun Americanized Negro- “You’ll be sor……………ree…….!!! “Pride will go before The Fall”! Maybe in a week, weeks, or a year or two, no man knows “The Exact Date or Time”! Each day from now own is your chance! Don’t shoot the messenger, we warned you long before 2020! 

    Peace Out…

  2. in 1918, Spanish Flu invaded New Orleans, 800 died, 14,000 got it and many recovered. Over 3000 died in all of Louisiana. The cause of spreading was WW 1 and New Orleans was the port where materials, food, equipment, and soldiers went and came back to the USA. New Orleans and Morgan City were portals that many carriers of the virus came thru.
    Morgan City leaders deceided to ban people from having group gahterings and events with close interactions which impeded many businesses. The ban was made known to all people and even churches voluntarily stopped meetings.
    Within a few weeks, new virus numbers were dropping and the spread was coming to an end. All the bans and stop of social activity proved to be the best effective method that people did that ended the virus.
    95% of the techniques back then to deal with it if you get any virus, is still used today to help people cope while they have it.
    To help with breathing back then, people would use Vicks Vapo Rub treatments on themselves and dissolved in hot water, which helped easier breathing.
    This got many people thru the Spanish Flu and I can remember this as a primary home treatment thru the 50s, 60s, 70s by our grandparents.

    Ohh,,, Outside of China, Italy has the largest deaths from CoronaVirus….
    I ask you to “google”, “Battle of the Oranges” and see how the people of Italy did not heed their leaders and thru their lust for pleasure, they have contaminated the whole country ! Lets not do that here in the USA !
    Still Available. Research !
    Vicks VapoRub is a mentholated topical ointment, part of the Vicks brand of over-the-counter medications owned by the American pharmaceutical company Procter & Gamble. VapoRub is intended for use on the chest, back and throat for cough suppression or on muscles and joints for minor aches and pains.
