Two more MERS cases confirmed by Saudi health ministry
Over the weekend and through today, Saudi Arabia's Ministry of Health (MOH) reported two MERS-CoV cases, bringing the total number of cases detected in February so far to eight.
The first new MERS-CoV (Middle East respiratory syndrome coronavirus) case involves a 72-year-old man from Wadi ad-Dawasir. The man's contact with camel was unknown, and he was not a healthcare worker. He is listed as a primary case, meaning it is unlikely he contracted the virus from another person.
The second case, noted today, occurred in a 40-year-old man from Najran. His case is also listed as primary, and his camel contact status is unknown.
Saudi Arabia reported 15 cases in January, including a probable healthcare-related cluster of 6 cases in Abha.
The World Health Organization (WHO) said in its latest monthly update that, since 2012, it has received reports of 2,499 MERS-CoV cases, at least 861 of them fatal. The vast majority of these cases were in Saudi Arabia.

WHO: 4 African countries license Ebola vaccine
The Democratic Republic of the Congo (DRC), Burundi, Ghana, and Zambia have licensed Merck's Ervebo—the rVSV-ZEBOV Ebola vaccine—according to the WHO.
The move allows Merck to stockpile the vaccine and distribute it to countries most at risk of Ebola virus disease outbreaks. Once licensed, the vaccine can be used outside of research protocols and clinical trials.
"The approval of the Ebola vaccine by these countries is another milestone in the fight against this unforgiving disease," said WHO Director-General Tedros Adhanom Ghebreyesus, PhD, in a news release. "Africa has rallied to cement hard-fought progress to keep its people safe from Ebola."
Ervebo has been used on almost 300,000 people in the DRC since August 2018, when the country's current Ebola outbreak began. Preliminary studies suggest the vaccine is 97.5% effective in preventing Ebola transmission.
