Influenza Laboratory Surveillance 2013-14

The 2013-14 Influenza Season starts in October and ends in May.  Here are some guidance documents for assistance in determining proper specimen collection and submission of specimens for surveillance and diagnostic testing.

RSV Updates

Visit the Respiratory Syncytial Virus (RSV) webpage for the latest on RSV surveillance for the 2013-14 season.  You can view Montana's RSV activity on a weekly basis, by region of the state, as well as gather other valuable RSV surveillance information.

The MTPHL has completed validation studies, and is now offering RSV testing by PCR. This testing will take the place of RSV DFA testing previously offered.  Although the DFA assay was quite specific, PCR offers improved sensitivity. The CPT code for RSV PCR is 87798 and the cost will be $95.00, similar to other molecular assays. Specimen source is either a nasopharyngeal swab or a nasal aspirate.

Carbapenem - Resistant Enteric Isolates

Round up these isolates & send to MTPHL - The June 25th MMWR reports that the Centers for Disease Control and Prevention (CDC) has identified three carbapenemase-producing Enterobacteriaceae that are resistant via the NDM-1 metallo-beta-lactamase  (NDM MBL) rather than KPC.  All three recently had medical care in India where this resistant mechanism is common. If any clinical laboratories in Montana have identified carbapenem-resistant enteric isolates from people who have had recent exposure to medical care in India or Pakistan, please submit these isolates to the Montana Public Health Laboratory.    MTPHL will perform initial testing for carbapenemases, and refer screen positive isolates to CDC for additional testing.  The full MMWR article can be accessed here.
