Five US health workers monitored for three weeks by doctors in Nebraska after being exposed to Ebola in West Africa have all been released, officials said. They are all clinicians who worked with Boston-based aid group Partners in Health. The five treated in Nebraska were exposed to Ebola in Sierra Leone in March, but did not develop the disease. "All five people have now completed their quarantine period for Ebola," Nebraska Medicine said on Twitter.
An explosion and a fire erupted on an offshore oil platform operated by Mexico's Pemex on Wednesday, killing at least four workers, injuring 16 and forcing 300 to be evacuated. Eight firefighting vessels with water cannons were deployed to battle the blaze as smoke billowed skyward at the Abkatun A-Permanente platform on the Gulf of Mexico's Campeche Sound. Some 300 workers were taken to other platforms in the area, while the injured were transported to Pemex's general hospital in Ciudad de Carmen.
