More than 200 people had initially been placed under observation following the woman’s death. In a statement sent to the WHO Tuesday, Russian health authorities said they conducted an investigation “following the identification of a case of community acquired pneumonia” and that “no pathogens of dangerous infectious diseases were detected among any of the contacts.”
The WHO said they have remained in contact with Russian authorities and “offered technical support.”
The EU and the U.S. are both monitoring the situation closely. The European Commission and countries are set to discuss the case at Wednesday’s Health Security Meeting, according to a Commission spokesperson.
But the U.S. is growing increasingly concerned with Russia’s transparency over the case. U.S. Secretary of State Marco Rubio on Tuesday urged Russia to share more information, adding that it would be “irresponsible” to speculate until then.
The Wall Street Journal reported Wednesday that the U.S. sent a formal diplomatic message to Russia requesting more information about the woman’s death and reminding the Kremlin that it has obligations under international law to share information about disease outbreaks in a timely manner.
The WHO said Tuesday that the risk is “moderate to low” for the Irkutsk region, “low” for Russia and “very low” for Europe.
