Candida auris

Multidrug-resistant Candida auris: Update on Current U.S. Epidemiology, Clinical Profile, Management, and Control Strategies

Date: Thursday, June 20, 2019

Time: 2:00 - 3:00 p.m. (Eastern Time)

Candida auris (C. auris) is an emerging fungus that presents a serious global health threat. CDC is concerned about C. auris for 3 main reasons:

  1. It is often multidrug-resistant, meaning multiple antifungal drugs are less or not at all effective in treating C. auris.
  2. It is difficult to identify with standard laboratory methods, and it can be misidentified in labs without specific technology. Misidentification may lead to inappropriate management.
  3. It has caused outbreaks in healthcare settings. It is important to quickly identify C. auris in a hospitalized patient so that healthcare facilities can take special precautions to stop its spread.

Most C. auris cases in the United States have been detected in the New York City area, New Jersey, and the Chicago area. Clusters of cases have also recently been described in Florida, Texas, and California. C. auris cases in the United States are originally a result of inadvertent introduction in the United States from a patient who had received healthcare in a country where C. auris has been reported. Most cases now are a result of local spread after such an introduction.

During this COCA Call, CDC presenters will

  • Provide an update on the current status of C. auris
  • Explain why it is a public health threat
  • Review current U.S. epidemiology and resistance patterns to antifungal drugs
  • Discuss clinical considerations when treating patients for C. auris
  • Lay out steps for identifying and controlling C. auris

If you are unable to attend this live COCA Call, the webinar will be available to view under the “Call Materials” tab a few days after the call takes place. Free continuing education (CE) will still be available.

CDC News and Announcements

One Health Zoonotic Disease Prioritization Workshop Names Eight Zoonotic Diseases of Most Concern in the United States

CDC and its U.S. government partners have released the first federal collaborative report listing the top zoonotic diseases of national concern for the United States.

CDC, U.S. Department of the Interior (DOI), and U.S. Department of Agriculture (USDA) developed the report after jointly hosting a One Health Zoonotic Disease Prioritization Workshop for the United States. During the workshop, agencies agreed on a list of eight zoonotic diseases that are of greatest concern to the nation and made recommendations for next steps using a One Health approach.

"Every year, tens of thousands of Americans get sick from diseases spread between animals and people. CDC's One Health Office is collaborating with DOI, USDA, and other partners across the government to bring together disease detectives, laboratorians, physicians, and veterinarians to prevent those illnesses and protect the health of people, animals, and our environment," said Casey Barton Behravesh, M.S., D.V.M., Dr.P.H., Director, One Health Office, CDC.

The zoonotic diseases of most concern in the United States are—

Six out of every ten infectious diseases in people are zoonotic, which makes it crucial that the nation strengthen its capabilities to prevent and respond to these diseases using a One Health approach. One Health recognizes the connection between people, animals, plants and their shared environment and calls for experts in human, animal, and environmental health to work together to achieve the best health outcomes for all.

This workshop was the first time multiple government agencies in the United States worked together on this topic and is a critical step towards a coordinated U.S.-specific approach to One Health. The workshop report outlines the process, the resulting list of prioritized zoonotic diseases, and participants' discussions and recommendations.

The report is a new resource for One Health organizations, the media, and other stakeholders that includes recommendations on how to work together to address the prioritized diseases and strengthen One Health efforts in the United States.

The U.S. One Health Zoonotic Disease Prioritization Report full version as well as a two page overview of the report are both available to download on CDC's One Health Domestic Activities webpage.

Seasonal Influenza


2018–2019 Influenza Season Week 21 ending May 25, 2019

All data are preliminary and may change as more reports are received.

According to this week’s FluView report, influenza activity is low with levels of influenza-like-illness (ILI) remaining at 1.5%. While only one state reported widespread flu activity, another three flu-related pediatric deaths were reported to CDC this week. Two occurred during the current 2018–2019 season, bringing the total number of flu-related deaths in children this season to 111. One death occurred during a prior season.

Flu viruses circulate year-round, though at low levels over the summer in the United States so sporadic flu infections and outbreaks may continue to occur. CDC continues to recommend vaccination as long as flu viruses are circulating until all vaccine expires at the end of June. CDC also recommends prompt antiviral treatment in people with flu symptoms who are very sick or who are at high risk of developing serious flu illness.

An overview of CDC's influenza surveillance system, including methodology and detailed descriptions of each data component, is available. Read the full situational update. View the current United States flu activity map.

Novel Influenza A Virus:

One human infection with a novel influenza A virus was reported by Michigan. This person was infected with an influenza A(H1N1) variant (A(H1N1)v) virus. The patient is over 65 years of age. The patient was hospitalized, and completely recovered from the illness. While no exposure to swine has been reported, an investigation is ongoing into the source of the patient’s infection. This is the first A(H1N1)v virus infection detected in the United States in 2019.

Influenza viruses that circulate in swine are called swine influenza viruses when isolated from swine, but are called variant viruses when isolated from humans. Seasonal influenza viruses that circulate worldwide in the human population have important antigenic and genetic differences from influenza viruses that circulate in swine.

Early identification and investigation of human infections with novel influenza A viruses are critical so that the risk of infection can be more fully understood and appropriate public health measures can be taken. Additional information on influenza in swine, variant influenza infection in humans, strategies to interact safely with swine and additional information regarding human infections with novel influenza A viruses are available.

Ebola in Democratic Republic of the Congo

  • There is an outbreak of Ebola in the North Kivu (Kivu Nord) and Ituri provinces in the northeastern part of the Democratic Republic of the Congo (DRC).
  • Travelers to this area could be infected with Ebola if they come into contact with an infected person’s blood or other body fluids.
  • Travelers should seek medical care immediately if they develop fever, headache, body aches, sore throat, diarrhea, weakness, vomiting, stomach pain, rash, or red eyes during or after travel.

·        CDC has provided recommendations to ensure workers with potential occupational exposure to Ebola are healthy when they return to the United States.

        Clinician Information

  • Health Information for Travelers to DRC
  • Viral Hemorrhagic Fevers in CDC Health Information for International Travel ("Yellow Book")
  • North Kivu and Ituri provinces are among the most populated in DRC. These provinces share borders with other countries (Rwanda, South Sudan, and Uganda) with frequent cross-border movement for personal travel and trade. The provinces have been experiencing a prolonged humanitarian crisis and deteriorating security, which are limiting public health efforts to respond to this outbreak. The US Department of State has identified this part of the country as a “reconsider travel” zone because of armed conflict.
