Providers' estimations vs. TDH surveillance records
| Disease | Respondents' estimated no. of cases they diagnosed in the previous 12 months* | No. of confirmed and probable cases (TDH surveillance data) | ||
|---|---|---|---|---|
| 2012 | 2013 | 2014 | ||
| WNV | 46–230 | 33 | 24 | 16 |
| La Crosse encephalitis virus | 26–70 | 9 | 23 | 11 |
| St. Louis encephalitis | 2–10 | 0 | 0 | 0 |
| Eastern equine encephalitis | 7–35 | 0 | 0 | 0 |
| Dengue | 25–125 | 6 | 9 | 2 |
| Chikungunya | 22–110 | n/a† | n/a† | 42 |
TDH = Tennessee Department of Health; WNV = West Nile virus.
*
These ranges created by multiplying the number of respondents for each category by the range for that category. For example, 46 respondents reported diagnosing between one and five patients with WNV, leading to a range of 46–230.
†
Chikungunya was not made reportable in Tennessee until 2014.
