Ivermectin and 'emergency kits' protect you from plague

What we know

On October 2, 2026, Darya Shipilova, a 28-year-old worker at the Irkutsk Anti-Plague Research Institute in Siberia, died after falling ill at work. A Russian official first wrote that she had died of plague and then edited the post to add 'possibly'; Russia's health watchdog has described the death as pneumonia of unknown cause. Nearly 200 contacts were placed under medical observation. The World Health Organization said that, based on the unofficial information available, the risk to the general population appears to be low. As of early October 2026 the cause of death had not been officially confirmed.

Within days the case was being used to sell products. An AFP report published on October 8, 2026 found influencers and 'prepper' accounts promoting a roughly 300-dollar emergency kit from The Wellness Company, a brand fronted by cardiologist Peter McCullough. Posts with plague hashtags urged people to prepare in advance, and some carried personal discount codes. The kits were promoted for the antibiotic doxycycline and for other prescription drugs, including ivermectin.

Ivermectin is an antiparasitic drug. The US Food and Drug Administration has approved it in tablet form for specific infections caused by parasitic worms, and in topical forms for head lice and rosacea. Plague is caused by a bacterium, Yersinia pestis, and ivermectin does not appear among the treatments recommended by the US Centers for Disease Control and Prevention (CDC). Plague researcher Paul Keim of Northern Arizona University told AFP that ivermectin 'is never really used for a bacterial disease'.

Plague is treatable. CDC guidance lists gentamicin and fluoroquinolone antibiotics as first-line treatment in the United States, with doxycycline also used for the bubonic form, for 10 to 14 days, and says treatment should begin as soon as plague is suspected. The WHO states that bubonic plague kills 30 to 60 percent of patients and that pneumonic plague is always fatal when left untreated, but that recovery rates are high when treatment starts within 24 hours of symptoms. That is an argument for fast medical care, not for home stockpiles: the right drug, dose and route depend on the form of the disease, and severe cases need hospital treatment.

Preventive antibiotics have a narrow role. The CDC recommends a seven-day course only for people with a known exposure, such as close, sustained contact with a pneumonic plague patient. Keim told AFP there is no reason for people in North America to take doxycycline in response to the Russian case, and warned that unnecessary use can disturb gut bacteria and encourage antibiotic resistance. Infectious disease specialist Isaac Bogoch of Toronto General Hospital said of plague, 'We know how to treat it', and added that the Russian case is not the type of infection that would cause a pandemic.

The pattern is familiar. AFP noted that ivermectin was also promoted as a cure for hantavirus after a cruise ship passenger was infected in May 2026, and that vitamin D3 and zinc were marketed during the 2026 Ebola outbreak in the Democratic Republic of the Congo, although neither treats that disease.

Common claims

• Ivermectin can prevent or treat plague.False. Plague is a bacterial infection; ivermectin is an antiparasitic and is not part of plague treatment guidance.
• Keeping antibiotics at home protects you from plague.Not supported. Preventive antibiotics are recommended only after a known exposure, for seven days, under medical direction.
• Plague cannot be treated.False. It responds to several antibiotics when treatment starts early.
• The Irkutsk death was confirmed as plague.Unconfirmed as of early October 2026. Russian authorities described pneumonia of unknown cause.
• The Irkutsk case means a plague pandemic is coming.Not supported. The WHO assessed the risk to the general population as low on the information available.
