Abstract

Headache is one of the most common symptoms of patients applying to emergency departments. In the majority of these patients the cause is usually primary. Although secondary headaches are less common, the diagnosis of the underlying reasons is important since they may be due to a potentially dangerous cause. Headache is also a common symptom of infection. The first symptom of infection can be a serious headache. Headaches which do not respond to medical treatment usually suggest secondary headache. Crimean-Congo haemorrhagic fever (CCHF) is an endemic disease with high mortality. Timely diagnosis as well as treatment of patients with high rates of transmission is also important in terms of disease prevention measures. In this study, a patient diagnosed as CCHF as a cause of secondary headache has been reported.
