Individuals with dengue fever are at a higher risk of being affected with stroke, especially during the first 2 months following infection, finds a study published in the journal CMAJ (Canadian Medical Association Journal) .
"Clinicians in dengue-endemic areas should be aware of this association, especially for patients with dengue who have neurologic deficits or for patients with stroke who have unexplained fever," writes Dr. Chia-Hung Kao, Department of Nuclear Medicine and PET Center, China Medical University Hospital, Taichung, Taiwan, with coauthors.
Dengue is a mosquito-borne viral infection that infects at least 100 million people every year around the world, with about 4 billion people at risk of the illness, which includes dengue hemorrhagic fever that can lead to spontaneous bleeding, organ failure and death. It is found in many countries in South and Southeast Asia, Africa, South America, the Caribbean, in the United States and more.
"Our findings may help with clinical risk evaluation and may serve as a basis for further investigation of the pathogenesis of dengue-related stroke," conclude the authors.
