Hi thanks for contacting HCM.... See mosquito bite can transmit certain infection like dengue , malaria , chikungunya Like febrile illness..... You feel feverish....so it could be febrile illness or it could only be congestive symptom by viral infection..... Symptomatic treatment done.... I would advise following investigation... -CBC -peripheral smear examination for parasites -liver enzymes estimation Take paracetamol for fever... Benadryl like drug might taken for relieving inflammation.... Water more. Healthy diet taken... Echinacea herb that help in resisting infection by flu... Now according to further presentation of symptom in one or two days detail investigation can be done.... Take care. Dr.Parth
