Clinical symptoms in rhesus monkeys challenged with HPAIV.

Respiratory rate (A) and body weight (B) were measured soon after anesthesia. The amount of consumed food was recorded daily (C). Orange and red lines show the data of the monkeys inoculated with 1 × 107 PFU (#27, circle; #28, square) or 1 × 108 PFU (#32, circle; #33, square), respectively. A purple line shows the mean of the data of the monkeys inoculated with 3 × 106 PFU.
