Dear Sir,

Dengue infection is a common tropical mosquito-borne arboviral infection. This disease can present with acute febrile illness accompanied with bleeding complications. The infection can be seen in many tropical countries, especially for those in Southeast Asia. However, the diagnosis of dengue can be sometimes difficult, and there are many infections that can mimic dengue. [1] In the situation of emerging influenza, the misdiagnosis of novel H1N1 infection to be dengue can be seen. [2] Nevertheless, a more complex case can be expected if there is a concurrent infection.

Here, the authors would like to introduce an interesting case of concurrent infection of dengue and novel H1N1 infection. The indexed case is a male nurse who works in a primary care unit. This patient was sent to the hospital with the complaint of fever, fainting, and falling. On the day that the case was sent to the physician, the patient routinely worked in primary care unit but felt febrile. He fell down in the toilet due to fainting symptom, and a severe contusion work was observed at his head. Due to high fever and abnormal hematoma at scalp, the laboratory examination was done and the complete blood count showed thrombocytopenia. This case was further confirmed for dengue infection by serological confirmation. Nevertheless, the additional laboratory test on influenza was also done, and the result showed positive test for novel H1N1 infection. The patient was admitted and treated by fluid replacement therapy as well as anti-influenza drug. The patient fully recovered within 1 week. As known, this case was the first report of concurrent dengue and novel H1N1 infection.
