On Tuesday, the WHO convened an urgent meeting to evaluate several possible vaccine candidates that could be administered during the outbreak. The meeting brought together a consortium of vaccine developers, researchers and government officials — a group the WHO created in 2021 to advance a Marburg vaccine. (Bendix, 2/14)

As temperatures rise, many tropical species once confined to the warmest parts of the globe are expected to climb to higher altitudes and creep farther from the equator. That already may be happening with mosquitoes carrying malaria, one of the world’s most devastating diseases and one that already kills more than 600,000 people a year. Evidence shows the insects are flapping their tiny wings to new locales in Africa, according to a new study. (Grandoni, 2/14)

More than a week removed from the disaster, with the death toll above 41,000, extended families and authorities on both sides of the Turkey-Syria border are still trying to figure out how many children have been orphaned, and how to care for them.

Russia’s system for supervising thousands of Ukrainian children uprooted during the war involves “re-education” camps and forced adoptions, U.S. researchers said Tuesday, calling it a sprawling operation directed by the Kremlin’s highest levels. According to a report from the Conflict Observatory, a State Department-supported initiative, Russia has placed at least 6,000 Ukrainian children at 43 camps and institutions stretching from Ukraine’s Russian-occupied Crimea region to Siberia and Russia’s Pacific coast, or with new families, as part of its “systematic, whole-of-government approach to the relocation, re-education and, in some cases, adoption and forced adoption of Ukrainian children.” (Ryan, 2/14)

The two boys and three girls were born through cesarean section Sunday, in the pregnancy’s 28th week, at the University Hospital in Krakow. Weighing between 710-1,400 grams (25-49 ounces,) they were all put in incubators and given breathing support, but doctors said they are all doing fine, given their premature birth. (2/14)
