Russia Plague Scare: How Dangerous Is It and Could It Become Another Covid?

A suspected case of pneumonic plague in Russia has triggered international attention after a 28-year-old laboratory worker died from severe pneumonia, with nearly 200 contacts placed under medical observation and US agencies monitoring the situation. Russian authorities have not confirmed plague, with Rospotrebnadzor diagnosing pneumonia of unknown aetiology and finding no microorganisms linked to her work. Pneumonic plague, caused by Yersinia pestis, is the only form spreading directly between people via respiratory particles. Symptoms include fever, cough and shortness of breath, with death possible within 24 hours if untreated, though antibiotics are effective with early diagnosis. Experts say one case does not indicate a COVID-like pandemic, pending confirmation of infection and transmission.
