2019 Novel Coronavirus (SARS-CoV-2/COVID-19)

  • On January 31, 2020, the U.S. Department of Health and Human Services declared a Public Health Emergency which included updated travel limitations and quarantine measures.
  • On January 30, 2020, the U.S. Department of State issued a Level 4 Travel Advisory asking people not to travel to China due to the 2019-nCoV outbreak.
  • On January 30, 2020, the World Health Organization (WHO) declared the SARS-CoV-2 outbreak a Public Health Emergency of International Concern.
  • As of January 28, 2020, the Centers for Disease Control and Prevention (CDC) travel alert to China to is a Warning - Level 3 - Avoid Nonessential Travel.

There have been no confirmed cases of COVID-19 in Dallas County. Dallas County Health and Human Services is continuing to work closely with the CDC and the Texas Department of State and Health Services to monitor the outbreak of 2019 novel (new) coronavirus infection, called COVID-19, caused by a coronavirus termed SARS-CoV-2, that was first detected in the city of Wuhan, China. 

What is SARS-CoV-2?

2019 Novel Coronavirus (SARS-CoV-2) is a virus (more specifically, a coronavirus) identified as the cause of an outbreak of respiratory illness (COVID-19) first detected in Wuhan, China. Early on, many of the patients in the outbreak in Wuhan, China reportedly had some link to a large seafood and animal market, suggesting animal-to-person spread. However, person-to-person spread has been confirmed. At this time, it’s unclear how easily this virus can be spread between people.  

Signs and symptoms of SARS-CoV-2 infection commonly include fever, cough, and difficulty breathing. Sore throat also has been reported in some patients. This novel coronavirus has the potential to cause severe pneumonia and death. Risk factors for severe illness are not yet clear, although older patients and those with chronic medical conditions may be at higher risk for severe illness. The latest situation summary updates are available on CDC’s web page(Source: About COVID-19), CDC)

Guidance for Travelers or Persons with Close Contact to a Laboratory-Confirmed SARS-CoV-2 Patient

For implementation beginning Monday, 2/3/2020. New travel procedures were announced in a Presidential Proclamation on Novel Coronavirus for travelers who have been in China during the past 14 days, including US citizens or residents and others who are allowed to enter the US. They will be asked to monitor their health, in coordination with their the local health department, for a 14 day period after leaving China, including taking their temperature with a thermometer twice a day and monitoring themselves for symptoms. Depending on their health and travel history, they will be asked to practice social distancing and have some restrictions placed on their movement for the 14 day time frame.

If you have recently traveled from China or if you had close contact with an individual confirmed to have COVID-19 and develop a fever, cough, or have difficulty breathing, please do the following immediately:

  • Seek medical care right away; call ahead before going to see a doctor or emergency room. Tell them your symptoms and travel history (or close contact with a confirmed COVID-19 case, if applicable). Always wear a mask when leaving your home. Print out and give them this card (简体中文).
  • After you have been seen by a medical provider, stay home and avoid contact with others.
  • Avoid travel on public transportation (such as bus, subway, train, or airplane) until the illness resolves.
  • Cover your nose and mouth with a tissue or your sleeve (not your hands) when coughing or sneezing.
  • Wash hands often with soap and water for at least 20 seconds to avoid spreading the virus to others. Use an alcohol-based hand sanitizer if soap and water are not available.

What is a novel coronavirus?

A novel coronavirus is a new coronavirus that has not been previously identified. The virus causing coronavirus disease 2019 (COVID-19), is not that same as the coronaviruses that commonly circulate among humans and cause mild illness, like the common cold.

A diagnosis with coronavirus 229E, NL63, OC43, or HKU1 is not the same as a COVID-19 diagnosis. Patients with COVID-19 will be evaluated and cared for differently than patients with common coronavirus diagnosis.

How does the virus spread?

The new coronavirus seems to be spreading from person-to-person. Learn what is known about the spread of COVID-19.

What are the symptoms of COVID-19 infection?

Patients with confirmed COVID-19 have reportedly had mild to severe respiratory illness with symptoms of fever, cough, and/or shortness of breath.

At this time, CDC believes that symptoms of COVID-19 may appear in as few as 2 days or as long as 14 days after exposure. This is based on what has been seen previously as the incubation period of MERS coronaviruses.

Can someone who has had COVID-19 spread the illness to others?

The virus that causes COVID-19 is spreading from person-to-person. Someone who is actively sick with COVID-19 can spread the illness to others. That is why CDC recommends that these patients be isolated either in the hospital or at home (depending on how sick they are) until they are better and no longer pose a risk of infecting others.

How long someone is actively sick can vary so the decision on when to release someone from isolation is made on a case-by-case basis in consultation with doctors, infection prevention and control experts, and public health officials and involves considering specifics of each situation including disease severity, illness signs and symptoms, and results of laboratory testing for that patient.

Current CDC guidance for when it is OK to release someone from isolation is made on a case by case basis and includes meeting all of the following requirements:

  • The patient is free from fever without the use of fever-reducing medications.
  • The patient is no longer showing symptoms, including cough.
  • The patient has tested negative on at least two consecutive respiratory specimens collected at least 24 hours apart.

Someone that has been released from isolation is not considered to pose a risk of infection to others.

Can someone who has been quarantined for COVID-19 spread the illness to others?

Quarantine means the separating a person or group of people who have been exposed to a contagious disease but have not developed illness (symptoms) from others who have not been exposed in order to prevent the possible spread of that disease. Quarantine is usually established for the incubation period of the communicable disease, which is the span of time during which people have developed illness after exposure. For COVID-19, the period of quarantine is 14 days from the last date of exposure because 14 days is the longest incubation period seen for similar coronaviruses. Someone who has been released from COVID-19 quarantine is not considered a risk for spreading the virus to others because the have not developed illness during the incubation period.

How can I help protect myself from COVID-19?

Visit the CDC's COVID-19 Prevention and Treatment page to learn about how to protect yourself from respiratory illnesses, like COVID-19.

What should I do if I had close contact with someone has COVID-19?

There is information for people who have had close contact with a person confirmed to have, or being evaluated for, COVID-19 available online.

Nuevo coronavirus del 2019 (2019-nCoV por sus siglas en inglés)

Desde el 28 de enero del 2020, los CDC anunciaron una alerta de viaje al país de China de nivel 3 que aconseja que viajantes eviten viajes no-esenciales.

Hasta la fecha, no ha habido ningún caso de 2019-nCoV en viajantes de China al condado de Dallas. Los CDC siguen monitoreando, de manera cercana, este brote de enfermedades respiratorias causadas por el nuevo coronavirus que fue detectado por primera vez en la ciudad de Wuhan, China.

¿Qué es el 2019-nCoV?

El nuevo coronavirus del 2019 (2019-nCoV por sus siglas en inglés) es un virus (específicamente, un coronavirus) que ha sido identificado como la causa de un brote de enfermedades respiratorias detectado por primera vez en Wuhan, China. Al principio, la mayoría de pacientes asociados con el brote en Wuhan, China reportaron alguna conexión con un mercado grande donde se venden mariscos y animales, sugiriendo una propagación de animal-a-humano. Aun, sin embargo, ha habido un número creciente de pacientes que no han reportado haber tenido alguna exposición a mercados animales, indicando que la propagación de humano-a-humano está ocurriendo. En este momento, aun so sabemos que tan fácil o sosteniblemente se está propagando este virus entre personas.
