As the number of Ebola cases continues to climb — the World Health Organization now counts at least 2,615 cases, with 1,427 deaths — countries across the world are increasing their efforts to combat the deadly virus.

In China, a test for the Ebola virus jointly developed by China’s Academy of Military Medical Sciences and a Shenzhen biotech company received approval Thursday for mass production.

Moscow sent eight doctors and scientists Friday from the Russian Plague Control Research Institute to help their Guinea colleagues battle the disease. They brought two mobile laboratories to test suspected patients.

And Air France — one of only a handful of airlines that is still running direct flights to the four countries affected by the Ebola outbreak — said it is taking additional precautions to protect its passengers and staff.

Dr. Vincent Feuille, medical officer at Air France, said he believes the risks of contagion are being controlled by the airline. However, several Air France staff and crew members believe these efforts are not sufficient, and some personal have recently refused to work on flights to the affected African countries.China gives green light to mass produce Ebola test kits as cases in Liberia top 1,000
