Journal Title: Българско списание за обществено здраве (Bulgarian Journal of Public Health) - Year 2014, Vol 0, Issue 3
Abstract
While most individuals infected with West Nile Virus (WNV) are asymptomatic, 20-40% of individuals infected with the virus show symptoms (1-4). Typical presentations of WNV infection include West Nile fever and neuroinvasive disease. West Nile fever presents as a self-limited illness, similar to dengue fever and other virally induced fevers. It is characterized by low grade fever, headache, malaise, back pain, myalgia, and anorexia for three to six days (2). WNV induced neuroinvasive disease includes encephalitis, meningitis or flaccid paralysis (5). Encephalitis is more commonly reported than meningitis in older patients whereas meningitis is more common in in children (6,7). Flaccid paralysis from WN virus is asymmetric and may present without other neuroinvasive manifestations (8,9) and is thought to be due damage of anterior horn of the spinal cord cells suggesting a poliomyelitis type mechanism (8- 14). Atypical presentations of WNV infection include rhabdomyolysis (15), fatal hemorrhagic fever with multiorgan failure and palpable purpura (16), hepatitis and pancreatitis (17,18), central diabetes insipidus (19), myocarditis (20), and myositis and orchitis (21). There has been one previously documented case of human WNV myocarditis; in this case, we present another case of myocarditis associated with WNV infection.
