Figure 3

Signs and symptoms of 138 children aged < 3 years presenting to the emergency department of a tertiary referral hospital with single virus ARTI. The proportions of presenting signs and symptoms were compared between virus groups using logistic regression analysis and multivariate adjustment for demographics and relevant clinical history (stepwise). Significant proportional differences (P < 0.05) between virus groups are depicted and include fever (FLU vs RSV, P = 0.01; FLU vs HRV, P = 0.01) and other findings (cough, crepitations, dyspnea and tachypnea).
