###Human: How to recover from dengue and typhoid? ###Assistant: Hi. Your friend appears to have severe dengue. Kindly do blood cultures for typhoid fever. Blood culture helps us to identify the presence of salmonella, and it guides the choice of antibiotic therapy. The petechiae can occur due to low platelet count. The bluish lips or cyanosis should be evaluated further. You have to do chest X-ray and arterial blood gas test soon. I suggest you do an holo-abdominal ultrasound and a plain abdominal X-ray. Elevation in liver function tests are seen in dengue or typhoid, and the liver can be enlarged in dengue. But intestinal perforation is the catastrophic complication of typhoid fever. I would recommend aggressive fluid resuscitation. If there is any sign of severe bleeding or unstable vital signs, a blood transfusion can be given with fresh whole blood or fresh packed red blood cells. Ceftriaxone always works well for typhoid fever. Identifying the complication is essential.
