Determining serotype for Haemophilus influenzae (Hi) and serogroup for Neisseria meningitidis (Nm) is crucial for identifying potential outbreaks and determining appropriate public health responses. Several new commercial multiplex polymerase chain reaction (PCR) assays capable of simultaneously testing a single specimen for an array of pathogens that cause blood infections, meningitis, or encephalitis are available. These assays can rapidly identify Hi and Nm species, but most do not determine serotype or serogroup. Laboratories should continue to perform culture and use validated, specific real-time PCR assays capable of detecting and differentiating all six serotypes (a-f) of Hi and six serogroups (A, B, C, W, X, and Y) of Nm; otherwise, additional steps need to be taken including performing a reflex culture or at a minimum retaining a clinical sample for further testing.

The Centers for Disease Control and Prevention (CDC) is collaborating in a coordinated public health response to the Department of Defense (DoD) announcement on May 26 of the first mcr-1 gene found in bacteria from a human in the United States. Escherichia coli (E. coli) bacteria carrying the mcr-1 gene were found in a urine sample from a person in Pennsylvania with no recent travel outside of the United States who presented to a clinic with a urinary tract infection. The mcr-1 gene makes bacteria resistant to the antibiotic colistin, which is used as a last-resort drug to treat patients with infections caused by multidrug-resistant bacteria, including carbapenem-resistant Enterobacteriaceae (CRE). The mcr-1 gene exists on a plasmid, a small piece of DNA that is capable of moving from one bacterium to another, potentially spreading antibiotic resistance to other bacterial species. CDC is issuing this HAN notice as a reminder to U.S. healthcare facilities about recommendations to prevent antibiotic resistant infections and alert them to additional recommendations for detecting and reporting bacteria with the mcr-1 gene.

The amount of opioids prescribed in the U.S. quadrupled from 1999-2014. Unfortunately, opioid-related overdose deaths have increased in parallel with prescribing increases, and the amount of pain that patients report remains unchanged. The CDC Guideline for Prescribing Opioids for Chronic Pain provides recommendations for safer and more effective prescribing of opioids for chronic pain in patients 18 and older in outpatient settings outside of active cancer treatment, palliative care, and end-of-life care. During this COCA Call, clinicians will hear an overview of the CDC recommendations and learn when and how opioids should be initiated for chronic pain, how to assess risk and address harms of opioid use, and when and how opioids should be discontinued.

CDC scientists discovered Legionnaires’ disease in 1976, during one of the largest respiratory disease investigations in U.S. history. CDC’s disease detectives were called upon when people became sick with pneumonia, a serious lung infection, while attending an American Legion convention at a hotel in Philadelphia. Findings from the investigation suggested that a germ was being spread by the hotel’s air conditioning system. Six months later, CDC scientists identified that germ. It was a previously unknown bacteria, which they named Legionella (http://www.cdc.gov/legionella/index.html).

Extreme heat events, or heat waves, are a leading cause of weather-related deaths in the United States. Between 1999 and 2012, extreme heat caused more than 7,400 heat-related deaths in the United States. Extreme heat increases hospital admissions for heart disease, respiratory disease, and stroke.

On May 13, 2016, the Centers for Disease Control and Prevention (CDC) issued interim guidance (http://www.cdc.gov/mmwr/volumes/65/wr/mm6518e1.htm) that recommends Zika virus rRT-PCR testing of urine collected less than 14 days after symptom onset, along with testing of patient-matched serum samples, for the diagnosis of suspected Zika virus infection (1). The purpose of this Health Alert Network (HAN) health update is to further disseminate information about the interim guidance to clinical and public health professionals.
