Hello and welcome to HCM. Thank you for your query. I can understand your concern, but there are many other conditions transmitted from a mosquito bite that can present in a similar way, or rather these symptoms are more generalized towards such a presentation. These conditions are seen more often during this time of the year, being the monsoons. My advise would be the two following things: 1. Test for other conditions like dengue, chikungunya, typhoid, etc. 2. Initiate anti-malarial drugs, as from my experience malaria patients (50 %) of them return a positive result to the laboratory tests conducted to detect malaria. Most patients in such situations experience an improvement almost immediately after initiating a course of anti-malarial s. This condition is called Clinical Malaria. So, please discuss the above mentioned options, which I am sure will certainly help your husband recover at the earliest. I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications at: http://doctor.healthcaremagic.com/doctors/dr-shoaib-khan/64581 . I would gladly help you. Best wishes.
