PRESIDENT DONALD TRUMP is looking “very strongly” at the case of a Russian lab technician who died at a plague research centre in Irkutsk, Siberia.

Humans can be infected either by being bitten by an infected flea, contact with infectious bodily fluids or contaminated materials, or by inhaling respiratory particles from a patient with pneumonic plague.

Pneumonic plague is the most infectious form and can trigger severe epidemics through person-to-person transmission by inhaling respiratory particles.

Historically, plague was responsible for widespread pandemics with high mortality. It was known as the “Black Death” during the 14th century, responsible for more than 50 million deaths in Europe. Nowadays, plague is easily treated with antibiotics and the type of standard precautions we became so familiar with during the Covid-19 pandemic to prevent person-to-person........
