The World Health Organization has declared the southwestern Spanish province of Teruel high-risk for the spread of yellow fever, classifying it as one of more than 60 countries where transmission is ongoing or being actively observed.
Local authorities on Saturday declared a state of emergency after a case of the highly infectious disease was detected in one person.
The latest report by the US Centers for Disease Control and Prevention (CDC) ranks Mexico as a region with the second highest risk, with Taiwan also designated with a high risk rating.
Yellow fever, a viral disease, primarily affects people in Africa and the tropical Americas. Symptoms include fever, headache, body aches, vomiting and swollen glands, the CDC said.
The WHO report said all airports in Teruel have been placed under quarantine and trained health personnel are advised to offer any passengers affected with symptoms adequate care.
Yellow fever in Africa
More than 2,000 patients have been infected with yellow fever across 32 countries in Africa, but only 21 people have been diagnosed in Spain.
Last year, the virus was confirmed to have arrived in Spain from Central America by a visitor carrying the disease. Four people were hospitalized and quarantined at the Ertzruhe University Hospital, where they were treated, the CDC said.
The CDC added that there is no effective vaccine available for yellow fever, but the vaccine that is approved in Latin America and Europe has been shown to be effective in some cases.
The regional Ministry of Health has expressed its optimism that the state of emergency will be lifted.
The regional Spanish government of Valencia said in a statement that the country was cooperating with the WHO on prevention and improvement of education and infrastructure.
