THE World Health Organisation has declared the possible links between Zika virus and microcephaly in babies and other neurological emergencies a "public health emergency of international concern" (“Fears over the Zika virus prompt blood donation ban”, The Herald, February 4). The virus was discovered in the Zika forest in Uganda in 1947 by two Scottish scientists, George Dick, a pathologist trained in Edinburgh, and Alexander Haddow, an entomologist trained in Glasgow.

It is good to see that our scientists still busy researching the virus; a collaborative programme of research on Zika between the Medical Research Council Centre for Virus Research at the University of Glasgow and scientists in Pernambuco in Brazil has just been announced. This is in addition to the £1 million of UK money that the Research Council made available this week for Zika research. The Medical Research Council is a jewel in the crown of science, not only in Britain, but in the world. It supported Alexander Fleming. It is a great British institution. I hope that it remains so.
