2018 Flu Update
Mass Flu Update:
National Influenza Activity: During week 20 (May 13-19, 2018), influenza activity continued to decrease in the United States.
Viral Surveillance: Overall, influenza A(H3) viruses have predominated this season. Since early March, influenza B viruses have been more frequently reported than influenza A viruses. The percentage of respiratory specimens testing positive for influenza in clinical laboratories decreased.
Pneumonia and Influenza Mortality: The proportion of deaths attributed to pneumonia and influenza (P&I) was below the system-specific epidemic threshold in the National Center for Health Statistics (NCHS) Mortality Surveillance System.
Influenza-associated Hospitalizations: A cumulative rate of 106.6 laboratory-confirmed influenza-associated hospitalizations per 100,000 population was reported.
Influenza-associated Pediatric Deaths: One influenza-associated pediatric death was reported.
Outpatient Illness Surveillance: The proportion of outpatient visits for influenza-like illness (ILI) was 1.2%, which is below the national baseline of 2.2%. All 10 regions reported ILI below region-specific baseline levels. New York City, the District of Columbia, Puerto Rico and all 50 states experienced minimal ILI activity.
Geographic Spread of Influenza: The geographic spread of influenza in one state was reported as widespread; Guam, Puerto Rico and one state reported regional activity; seven states reported local activity; the District of Columbia, the U.S. Virgin Islands and 37 states reported sporadic activity; and four states reported no influenza activity.
Detailed weekly flu surveillance reports are posted on the Mass Public Health Blog.

CDC Campaign for the General Public: Take 3 Actions to Fight the Flu
Flu can make you miss work, school or even be hospitalized. You can take these 3 actions to fight the flu and the spread of germs to others this flu season.
1. Take time to get a flu vaccine.
2. Take preventive actions to stop the spread of germs.
3. Take flu antiviral drugs if your doctor prescribes them.
Vaccine Ordering and Locating Clinics
Providers Wishing to Order Flu Vaccine for Private Purchase:
The national Influenza Vaccine Availability Tracking System (IVATS) assists providers wishing to privately purchase flu vaccine. IVATS identifies available doses of influenza vaccine by formulation and distributor/vendor throughout the season.
· Location of Flu and Adult Vaccination Services:
Flu vaccination clinics are listed on the mylocalclinic.com website sponsored by the Massachusetts Health Officers Association (MHOA). MDPH urges agencies to post their clinics on this website. Many boards of health (BOHs) may have clinics that make flu and other vaccines available to both adults and children. BOHs can be contacted individually for questions about possible flu vaccination clinics in Massachusetts municipalities, including the age groups served.
HealthMap Vaccine Finder assists the public with locating influenza and adult vaccination services within their communities. It is a free, online service where users can search for locations that offer immunizations. Its staff works with partners such as clinics, pharmacies, and health departments to provide accurate and up-to-date information about vaccination services. MDPH urges providers and other agencies to register their locations on the HealthMap Vaccine Finder site too.
For questions about influenza please call the Massachusetts Department of Public Health Immunization Program at 617-983-6800 or your local board of health.
For questions about state-supplied influenza vaccine, please call the Vaccine Unit at 617-983-6828.
Although influenza-like illness activity in Massachusetts has remained at low intensity so far this season, we do have influenza in Massachusetts. Providers are urged to treat suspected influenza in high-risk patients, those with progressive disease, and all hospitalized patients with antiviral medications ASAP, regardless of negative RIDT results and without waiting for RT-PCR testing results.
Influenza activity is increasing across the country and CDC has received reports of severe influenza illness. Clinicians are reminded to treat suspected influenza in high-risk outpatients, those with progressive disease, and all hospitalized patients with antiviral medications as soon as possible, regardless of negative rapid influenza diagnostic test (RIDT) results and without waiting for RT-PCR testing results. Early antiviral treatment works best, but treatment may offer benefit when started up to 4-5 days after symptom onset in hospitalized patients. Early antiviral treatment can reduce influenza morbidity and mortality.
Since October 2015, CDC has detected co-circulation of influenza A(H3N2), A(H1N1)pdm09, and influenza B viruses. However, H1N1pdm09 viruses have predominated in recent weeks. CDC has received recent reports of severe respiratory illness among young- to middle-aged adults with H1N1pdm09 virus infection, some of whom required intensive care unit (ICU) admission; fatalities have been reported. Some of these patients reportedly tested negative for influenza by RIDT; their influenza diagnosis was made later with molecular assays. Most of these patients were reportedly unvaccinated. H1N1pdm09 virus infection in the past has caused severe illness in some children and young- and middle-aged adults. Clinicians should continue efforts to vaccinate patients this season for as long as influenza viruses are circulating, and promptly start antiviral treatment of severely ill and high-risk patients if influenza is suspected or confirmed
