There are now 131 cases in Colorado, according to public health officials.

COLORADO, USA — One hundred and thirty-one people in Colorado have tested presumptive positive for the novel coronavirus, COVID-19, and one person has died as of Sunday, March 15.

The person who died was an El Paso County woman in her 80s with underlying health conditions, according to a news release from the Colorado Department of Public Health and Environment (CDPHE). During a news conference, Gov. Jared Polis (D-Colorado) said she lived alone.

CDPHE released a public health alert after learning the woman attended bridge games at the Colorado Springs Bridge Center between Feb. 27 and March 3. If you or a close contact attended the center during those dates and are experiencing COVID-19 symptoms, officials recommend calling your health provider immediately.

“We’re extremely concerned about possible transmission both at the tournament and in communities after they went home,” said Kimberly Pattison, EPCPH Communicable Disease Program Manager. “Many attendees were older people who might be especially vulnerable to severe illness from COVID-19.”

With new guidance from the Centers for Disease Control and Prevention (CDC), providers are able to test patients independently of public health departments, so statistics regarding the number of presumptive positive cases are expected to change.

The results for anyone tested at a local level are considered “presumptive positive” until the CDC confirms the cases.

758 people been tested for COVID-19 at the state lab since they were made available on Feb. 28, according to CDPHE. Officials said private labs are biw also conducting tests, and are not required to report negative cases.

COVID-19 is a virus that first appeared in Wuhan, China in late 2019. Symptoms of COVID-19 can include fever, cough and breathing trouble. Most develop only mild symptoms. But some people, usually those with other medical complications, develop more severe symptoms, including pneumonia, which can be fatal.

>NOTE: Due to the large number of new cases that continue to come in, CPDHE said on March 14 it will shift to reporting aggregate data for new cases instead of listing the details of each individual case.

To help prevent the spread, people should:

Wash their hands often with soap and water for at least 20 seconds; Use an alcohol-based hand sanitizer that contains at least 60% alcohol if soap and water are not available.

Avoid touching their eyes, nose, and mouth with unwashed hands.

Stay home when they are sick.

Cover their cough or sneeze with a tissue, then throw the tissue in the trash.

Clean and disinfect frequently touched objects and surfaces.

Avoid close contact with people who are sick.

If you are feeling ill with symptoms similar to those associated with COVID-19 the Denver Department of Public Health and Environment (DDPHE) recommends the following:

Manage your symptoms at home the same way you manage other cold symptoms. To the extent possible, people with flu-like symptoms should remain at home.

If you need medical care, contact your primary care provider and schedule a visit. Let them know that you are concerned you might have COVID-19.

Only contact 911 for emergencies requiring immediate life-saving care and let them know if you are concerned you might have COVID-19.

Restrict visits to the hospital emergency room or urgent care - only individuals needing immediate care should visit these facilities. If you must visit an ER or urgent care facility, call ahead and let them know that you are concerned you might have COVID-19.

CDC's testing guidance includes three types of people:

Those who have symptoms such as fever OR lower respiratory symptoms (cough or shortness of breath) and have had "close contact" with a confirmed coronavirus patient within 14 days of their first symptoms. Those who have fever AND/OR lower respiratory symptoms, require hospitalization and have traveled to areas impacted by the epidemic in the last 14 days. Patients with fever and severe, acute lower respiratory symptoms who require hospitalization, and for whom no other diagnosis has been found — such as the flu. No travel or contact exposure is needed.

DDPHE said it's working with city leadership to ensure that public health and safety measures are ready to be implemented in the event of a local outbreak with community transmission.

Those measures could include limiting large gatherings and encouraging employers to allow employees to work from home whenever possible.
