HYDERABAD: The influenza group of viruses largely responsible for the unexplained
mystery fevers are difficult to trace as there are no tests for them.
Also, in general medical practice, these are largely clubbed as viral fevers and not investigated because they are known to be self-limiting and not life-threatening. But doctors have been left perplexed by delay in recovery and inability to pinpoint the cause.
In many cases, these fevers continue for over 15-20 days without any signs of improvement.
“While generally these kinds of fevers are categorised as viral fevers and tend to self-limit within a few days, we are now seeing some cases which are not recovering as expected. There are cases where a patient has been on paracetamol for over a week and still not recovered. They seem to be taking longer than usual to recover,” said a doctor from the state-run Fever Hospital, adding that majority of the cases did not require hospital admission.
