Overview

Annually, the prevalence of St. Louis encephalitis within the United States is estimated to be 651 cases. The incidence of St. Louis encephalitis is approximately 192 per 100,000 individuals worldwide. The majority of St. Louis encephalitis cases are reported in the United States. In the United States, the annual number of reported St. Louis encephalitis neuroinvasive disease cases reported fluctuates widely, as a result of periodic epidemics. St. Louis encephalitis infection is thought to confer life-long immunity against re-infection. St. Louis encephalitis affects men and women equally. There is no racial predilection to St. Louis encephalitis.[1]St. Louis encephalitis is a rare disease that tends to affect increased age and decreased age. Patients of all age groups may develop St. Louis encephalitis. [2]

Epidemiology and Demographics

Annually, the prevalence of St. Louis encephalitis within the United States is estimated to be 651 cases. The incidence of St. Louis encephalitis is approximately 192 per 100,000 individuals worldwide. The majority of St. Louis encephalitis cases are reported in the United States. In the United States, the annual number of reported St. Louis encephalitis neuroinvasive disease cases reported fluctuates widely, as a result of periodic epidemics. St. Louis encephalitis infection is thought to confer life-long immunity against re-infection.[1] The case-mortality rate of St. Louis encephalitis is ranges from 5% to 30%, with higher rates among the elderly, worldwide. [2] From 1964 through 2009, an average of 102 cases were reported annually (range 2-1,967).[3]

St. Louis Encephalitis Virus Neuroinvasive Disease Cases* Reported by Year, 1964-2010
Line Graph: Annually, the number of reported St. Louis encephalitis virus within the United States fluctuates widely. From 1964 through 2010, an average of 100 cases were reported annually (range 2-1,967).
  • Neuroinvasive disease includes cases reported as encephalitis, meningoencephalitis, or meningitis.[1]
St. Louis encephalitis virus neuroinvasive disease cases reported by year, 2004–2013
Bar Graph: In the United States, the number of St. Louis encephalitis cases reported each year vary. From 2004 through 2013, an average of 7 cases were reported annually (range 1–12).

Age

St. Louis encephalitis is a rare disease that tends to affect increased age and decreased age. Patients of all age groups may develop St. Louis encephalitis. [2]

Race

There is no racial predilection to St. Louis encephalitis.[1]

Gender

St. Louis encephalitis affects men and women equally.[1]

Geographical Region

In temperate areas of the United States, St. Louis encephalitis disease cases primarily occur in late summer or early fall. In the southern states, where climate is milder, cases may occur year round. Although the geographic range of the virus extends from Canada to Argentina, human cases have almost exclusively occurred in the United States. The majority of cases have occurred in eastern and central states, where episodic urban-centered outbreaks have recurred since the 1930s. The largest epidemic of St. Louis encephalitis neuroinvasive disease ever recognized occurred in the United States in 1975, with nearly 2,000 cases reported, primarily from the central states in the Ohio-Mississippi River Basin.[4]

Figure: From 2004 through 2013, St. Louis encephalitis virus neuroinvasive disease cases have been reported in Alabama (1), Arkansas (15), Arizona (4), Indiana (1), Kansas (2), Kentucky (1), Louisiana (8), Michigan (4), Mississippi (9), Missouri (2), New Hampshire (1), Nevada (1), North Carolina (3), Ohio (1), Oklahoma (1), Texas (12) and Washington (1).
St. Louis encephalitis virus neuroinvasive disease average annual incidence by county, 2004–2013
Figure: This map shows the distribution of St. Louis encephalitis's average annual incidence by county from 2004 through 2013. Counties are shaded according to incidences ranging from less than 0.20, 0.20 to 0.49, and greater than 0.50 per 100,000 population. Shaded counties are primarily in southern states
