Hi! Good evening! Joint pains following Chikungunya is a common feature. However, it is not due to higher levels of uric acid. Gouty arthritis is due to increased uric acid level but high uric acid level need not be correlated with gout. The best intervention at this level is dietary restriction like your father must avoid the foods which are rich in purines ( the breakdown of which results in uric acid formation) e.g beans, red meat, organ meals, alcohol (beer) etc. He must take lot of oral fluids to maintain a good urine output so that the excess of uric acid gets eliminated from the body. Regards!
