Swiss pharmaceutical giant Roche said Monday that US regulators had issued emergency authorisation to use its not-yet-approved diagnostic test for detecting the Zika virus in certain circumstances. The US Food and Drug Administration (FDA) issued a so-called Emergency Use Authorization for the LightMix Zika rRT-PCR test, even though it has yet to receive official clearance, allowing certified labs to use it in the hunt for the mosquito-borne virus. The announcement comes amid growing concern in the United States about Zika, which when it infects pregnant women can cause a severe birth defect known as microcephaly, in which babies develop abnormally small skulls and brains.
By Alex Lawler LONDON (Reuters) - Oil fell towards $49 a barrel on Monday, pressured by high output from Middle East OPEC members and as a stronger U.S. dollar weighed on commodities. Iraq, which has exported more crude from its southern ports in August, will continue ramping up output, its oil minister said on Saturday. Brent crude was 62 cents lower at $49.30 a barrel at 0904 GMT.
