Correlation between the characteristics of symptoms and clinical features
There were no significant correlations between age, age at onset of symptoms, gender, duration of symptoms, time to recovery of the lesions, stage of the bite reaction and skin test positivity to mosquito. The median duration of symptoms after onset were significantly longer in patients with ecchymosis [3.8 years (IQR 2.4-4.8) vs. 2.4 years (IQR 0.8-3.8); p=0.024], immediate wheals [3.8 years (IQR 2.5-5.1) vs. 2.5 years (IQR 0.9-4.1); p=0.047]. The median duration of symptoms was also significantly longer in children whose symptoms start in 20 min to 4 hours when compared to children by whom the symptoms develop later than 4 hours after mosquito bites [3.5 years (IQR 1.6-4.6) vs. 2.0 years (IQR 0.7-3.7); p=0.027]. There were no significant correlations between skin test positivity to mosquito and clinical features.
