Trump Set to Call Putin Over Russian Plague Outbreak.

President Trump said Tuesday he will speak with Russian President Vladimir Putin 'very soon' about a lab worker's death at a Siberian plague research institute.

• Daria Shipilova, 28, died Friday outside Irkutsk after reportedly breaking a pathogen-containing test tube.
• She worked at the nearby Anti-Plague Research Institute in Siberia.
• Pneumonic plague spreads through respiration and is nearly always fatal without antibiotic treatment.
• Soviet scientists in the 1980s engineered antibiotic-resistant plague bacteria for use as a biological weapon.

Why it matters: The cause of Shipilova's death has not been confirmed, but the circumstances have prompted concern about pathogen exposure and potential spread.

• Antibiotic-resistant plague strains, if involved, would significantly complicate any treatment or containment response.
