• BACKGROUND
• Maryland is once again preparing for the
  arboviral surveillance season. This surveillance
  program focuses on the detection, reporting, and
  management of West Nile virus (WNV) and other
  arboviruses to prevent human epidemics and animal
  epizootics. Non-human surveillance data from the
  last few years indicate that the virus is endemic
  in Maryland. It is therefore critical that we
  continue our surveillance efforts. Enhanced human
  arboviral surveillance begins this month, June,
  2007.
• ACTIONS REQUESTED
• To ensure rapid case investigations, I ASK THAT
  YOU PLEASE CONTINUE TO REPORT ANY SUSPECT CASE OF
  ENCEPHALITIS OR ASEPTIC MENINGITIS WITHIN 24
  HOURS (OF BEING NOTIFIED) TO YOUR LOCAL HEALTH
  DEPARTMENTS COMMUNICABLE DISEASE INVESTIGATION

• Dear Infection Control Professional,
• Maryland is once again preparing for the
  arbovirus surveillance season. This surveillance
  program focuses on the detection, reporting, and
  management of West Nile virus (WNV) and other
  arboviruses to prevent human epidemics and animal
  epizootics. As you may recall, WNV reappeared in
  Maryland in 2006.
• Only 11 human WNV cases were reported last year
  in Maryland, more than the previous year (5), but
  fewer than the peak of 73 cases in 2003. While
  we hope activity remains at this low level,
  historically, WNV outbreaks are difficult to
  predict. Additional non-human surveillance data
  from the last few years indicate that the virus
  is endemic in Maryland, putting all residents at
  risk of infection. It is therefore critical that
  we continue our surveillance efforts.
• Enhanced human arboviral surveillance begins this
  month June, 2007

annually in West Virginia beginning in June, and
peaking in August September. Please be
vigilant for cases of encephalitis occurring
during the warm summer months when mosquitoes may
be active, and assure that hospitalized persons
with encephalitis undergo appropriate testing.
The most efficient and complete testing is CSF or
serum IgM for a complete arbovirus panel La
