State to update surveillance of Delta variant of concern

REMOTE, (June 15, 2021): Today, the Centers for Disease Control and Prevention (CDC) labeled the Delta variant (B.1.617.2) as a variant of concern. This variant was first identified in India in December 2020, and has displayed increased transmissibility. The Delta variant has been identified in 17 counties in Colorado to date and currently makes up the second highest percent of variants in the state that have been confirmed through whole genome sequencing, falling just behind the Alpha variant (B.1.1.7).

The CDC defines a variant of concern as: 

A variant for which there is evidence of an increase in transmissibility, more severe disease (e.g.,  increased hospitalizations or deaths), significant reduction in neutralization by antibodies generated during previous infection or vaccination, reduced effectiveness of treatments or vaccines, or diagnostic detection failures. 

Experts stress that getting vaccinated can provide significant protection against illness, hospitalization, and death from COVID-19. Getting vaccinated also protects others around you from getting COVID-19. Current data suggests that it reduces the spread of infection, leading to fewer opportunities for new variants to develop and spread.  

Anyone who is not two weeks past the last dose of their vaccination series is not considered fully vaccinated and should continue to wear a mask in public indoor spaces, wash their hands frequently, practice physical distancing, and limit social gatherings with people outside their households. Anyone who is unvaccinated and is exposed to a person with COVID-19 or symptoms of COVID-19 should quarantine.

The Variant Sentinel Surveillance visualization on the state’s COVID-19 data dashboard will be updated to reflect this change during tomorrow’s regular 4 p.m. data update.

El estado actualizará el estado de monitoreo de la variante de preocupación Delta

REMOTO, (15 de junio de 2021): Hoy, los Centros para el Control y la Prevención de Enfermedades (CDC, por sus siglas en inglés) clasificaron a la variante Delta (B.1.617.2) como una variante de preocupación. Esta variante fue identificada por primera vez en la India en diciembre de 2020 y muestra tener un nivel de propagación alto. Hasta la fecha, la variante Delta ha sido identificada en 17 condados dentro de Colorado y tiene el segundo porcentaje más alto de variantes en el estado que han sido confirmadas a través de la secuenciación de genomas, quedando por detrás de la variante Alpha (B.1.1.7).

Los CDC definen a una variante de preocupación cómo: 

Una variante que demuestra tener un nivel más alto de propagación, una enfermedad más grave (por ejemplo, un incremento de hospitalizaciones o muertes), una reducción notoria en la neutralización de anticuerpos generado durante una infección previa o durante la vacunación, una reducción en la efectividad de los tratamientos o vacunas, o problemas para detectarla.  

Los expertos hacen hincapié en el hecho de que vacunarse puede brindar una protección significativa contra enfermedades, la hospitalización y muerte a causa del COVID-19. Vacunarse también protege a las personas alrededor suyo de contraer el COVID-19. Los datos actuales sugieren que reduce la propagación de la infección, lo que lleva a menos oportunidades para que nuevas variantes se desarrollen y propaguen.  

Cualquier persona que no ha pasado dos semanas después de su última dosis de la serie de vacunas es considerado no estar completamente vacunada y deberá continuar usando un tapabocas en ambientes cerrados públicos, lavarse las manos con frecuencia, practicar el distanciamiento físico y limitar las reuniones sociales con personas que no son de su vivienda. Cualquier persona que no esté vacunada y haya sido expuesta a una persona con COVID-19 o que tenga síntomas de COVID-19, deberá hacer cuarentena.

La visualización del programa de Vigilancia Centinela de Variantes en el tablero de datos de COVID-19 del estado será actualizado para reflejar este cambio durante la actualización regular de mañana a las 4 p.m.

CDC publishes options to reduce quarantine length

CDC and CDPHE continue to recommend a full 14 day quarantine as the ‘gold standard’

REMOTE, (Dec. 2, 2020): The Centers for Disease Control and Prevention (CDC) has published additional options to reduce the length of quarantine, while still continuing to recommend a full 14 day quarantine as the most effective way to reduce disease spread. CDPHE will be updating its guidance to explain when other, less protective options might be appropriate. 

A quarantine could only be shortened in the following situations: 

  • If exposed people do not develop symptoms, they may be released from quarantine after completing day 7 if they have a negative molecular or antigen test collected within 48 hours of ending quarantine. The test should be collected at least 5 days after their exposure.
  • People may stop quarantining after completing 10 days of quarantine without a test if they do not develop any symptoms.

Under no circumstances should the quarantine end before 7 days have fully passed.

“We need everyone to do everything possible to avoid all in-person interactions with people they don’t live with, whether they’ve had a known exposure to COVID-19 or not. The risks are too high right now with 1 in 41 Coloradans infected. The additional quarantine options provided by CDC give the public more flexibility on quarantining, which is sometimes necessary to sustain the response, allowing folks to do essential activities. But the gold standard remains to be a 14 day quarantine after any possible exposure,” said Rachel Herlihy, state epidemiologist, CDPHE. 

While people may leave quarantine earlier, if they follow these additional safety precautions they should continue to monitor themselves daily for symptoms of COVID-19 for a full 14 days. Some people may not get sick until 14 days after their exposure. That is why it is also important to wear a mask and keep physical distance (at least six feet) from others. 

Symptoms may appear 2-14 days after exposure to the virus. People with these symptoms may have COVID-19:

  • Fever or chills.
  • Cough.
  • Shortness of breath or difficulty breathing.
  • Fatigue.
  • Muscle or body aches.
  • Headache.
  • New loss of taste or smell.
  • Sore throat.
  • Congestion or runny nose.
  • Nausea or vomiting.
  • Diarrhea.

The new quarantine options also advise people to wait at least five days after their exposure date before getting tested, unless symptoms develop. Testing immediately after exposure isn’t helpful because it may be too early in the incubation period, and there isn’t enough viral material for the test to detect.

Follow the instructions on how to quarantine after exposure to prevent further transmission.  

Anyone with symptoms should get tested as soon as possible, stay away from others, and follow the instructions on how to isolate. Isolation is different from quarantining and is for people who are ill. 

We appreciate Coloradans’ patience while we update our webpages and guidance documents to explain the additional options provided by the CDC.  Continue to stay up to date by visiting

New CDC advisory: Use of cloth face coverings to help slow the spread of COVID-19

How to wear a cloth face covering

Face mask fit

Cloth face coverings should

  • fit snugly, but comfortably against the side of the face
  • be secured with ties or ear loops
  • include multiple layers of fabric
  • allow for breathing without restriction
  • be able to be laundered and machine dried without damage or change to shape

CDC on homemade cloth face coverings

CDC recommends wearing cloth face coverings in public settings where other social distancing measures are difficult to maintain (e.g., grocery stores and pharmacies), especially in areas of significant community-based transmission.

CDC also advises the use of simple cloth face coverings to slow the spread of the virus and help people who may have the virus and do not know it from transmitting it to others.  Cloth face coverings fashioned from household items or made at home from common materials at low cost can be used as an additional, voluntary public health measure.

Cloth face coverings should not be placed on young children under age 2, anyone who has trouble breathing, or is unconscious, incapacitated or otherwise unable to remove the mask without assistance.

“The cloth face coverings recommended are not surgical masks or N-95 respirators.  Those are critical supplies that must continue to be reserved for healthcare workers and other medical first responders, as recommended by current CDC guidance.”

Full guidance on homemade masks from CDC.

CDC official health advisory: Severe illness associated with using non-pharmaceutical chloroquine phosphate to prevent and treat Coronavirus disease 2019 (COVID-19)


Chloroquine phosphate, when used without a prescription and supervision of a healthcare provider, can cause serious health consequences, including death. Clinicians and public health officials should discourage the public from misusing non-pharmaceutical chloroquine phosphate (a chemical used in home aquariums). Clinicians should advise patients and the public that chloroquine, and the related compound hydroxychloroquine, should be used only under the supervision of a healthcare provider as prescribed medications.


The Centers for Disease Control and Prevention (CDC) has become aware of two individuals who ingested non-pharmaceutical chloroquine phosphate, a chemical for aquarium use that is commercially available for purchase at stores and through internet websites. One of the individuals died shortly after arrival to the hospital. The second individual was critically ill with severe gastrointestinal symptoms and cardiac conduction abnormalities. Upon recovery, the surviving individual reported to the media that they ingested the product to prevent infection with SARS-CoV-2, which causes coronavirus disease 2019 (COVID-19), after seeing information on the medical use of chloroquine on television. The product in their possession was in powder form inside a 2.2-lb. container and labeled “for Ornamental Fish Use Only”. CDC is also aware of unconfirmed media reports that these commercially available aquarium-use chemicals may be out of stock due to potential increased demand by the public.

At this time, there are no routinely available pharmaceutical products that are FDA-approved for the prevention or treatment of COVID-19.

Pharmaceutical chloroquine phosphate and hydroxychloroquine sulfate are approved by the US Food and Drug Administration (FDA) to treat specific medical conditions, such as malaria, lupus, and rheumatoid arthritis. Currently, these medications are being studied and evaluated as treatment for COVID-19; however, their efficacy to either prevent or treat this infection are unknown. In overdose situations or when used inappropriately, these medications can lead to severe toxicity, including cardiac rhythm disturbances such as prolonged QT, severe hypokalemia, cardiovascular collapse, seizures, coma, and death. Inappropriate uses include taking commercially available non-pharmaceutical preparations, taking chloroquine phosphate or hydroxychloroquine sulfate without a prescription, and taking additional doses not recommended by a healthcare provider. Chloroquine phosphate has a narrow therapeutic index—it can be toxic at levels not much higher than those used for treatment—which raises the risk of inadvertent overdose.

Recommendations for clinicians and public health officials

  1. Educate patients on the serious risks of misusing non-pharmaceutical chloroquine products and other aquarium use chemicals.
  2. Counsel your patients on the importance of taking medications only as prescribed and as directed by healthcare providers.
  3. Contact your local poison center (1-800-222-1222) to report cases and to obtain specific medical management of chloroquine and hydroxychloroquine poisoning.
  4. Adverse events related to pharmaceuticals can be reported to the FDA MedWatch program (
    Adverse events related to non-pharmaceutical products can be reported by emailing or calling 1-888-InfoFDA (1-888-463-6332).

    Recommendations for the public

    Do not ingest aquarium use products or any other chemicals that contain chloroquine phosphate. These chemicals are not intended for human consumption, and can lead to serious health consequences, including death.

    Medications like chloroquine phosphate and hydroxychloroquine sulfate should be taken only when prescribed by and under the supervision of your healthcare provider, and always according to the instructions provided.

    Seek immediate medical attention if you are experiencing any unexpected symptoms after taking chloroquine or hydroxychloroquine by contacting your healthcare provider or your poison center (1-800-222-1222).
