Dr Israel Molina, head of the International Health Programme of the Institut Català de la Salut (PROSICS) and researcher of the Infectious Diseases group at Vall d'Hebron Institute of Research (VHIR), and Dr Diana Pou, specialist in infectious diseases at PROSICS and VHIR, have been interviewed in several media to talk about zika virus.Despite the two cases detected in Catalonia, Dr. Molina said to El País that the probability of an epidemic in Spain is very low: "the density of mosquitoes and the number of infected people now is too low for an autochthonous transmission of the virus". However, in an interview with Diario Médico, he added that "the risk exists, although it is low, so we must be prepared to tackle any disease".In the radio station Rac1, Dr Pou appealed for calm, after receiving last week lots of calls and visits from people who have recently been in South America and were worried about the breaking news of the disease. She explained that in most of the cases the consequences of zika virus are mild: only 2 out of 10 infected people present fever, skin rash, joint pain and/or conjunctivitis from 4 to 7 days. Nonetheless, it has been detected an association with the Guillain-Barré syndrome and fetal impairment in pregnant women, such as microcephaly.The http://www.who.int/mediacentre/news/statements/2016/emergency-committee-zika-microcephaly/en/" World Health Organization has declared zika virus a Public Health Emergency of International Concern, due to the recent cluster of microcephaly cases and other neurological disorders reported in Brazil.
