Core body temperature as measured by telemetry.

<p>ITS telemetry devices were used to collect core body temperature data. (A) NHP 1; (B) NHP 2; (C) NHP 3; (D) NHP 4. The grey line represents baseline (mean of the telemetry data collected in the six days prior to challenge) for each animal. The diamonds represent fever (♦; > 1.5°C above baseline), hyperpyrexia (♦; > 3°C above baseline), and hypothermia (♦; > 2°C below baseline), and normal body temperature values (♦; a temperature falling between fever and hypothermia).
