Questions and answers

8 answers
Is pneumonic plague curable?

Yes. WHO says antibiotics cure plague, and that they work best when treatment starts early; it describes high recovery rates when pneumonic plague is treated within about 24 hours of symptoms beginning. Delay is dangerous, because the infection can become severe very quickly.

www.who.intwww.who.int
How deadly is pneumonic plague with treatment?

Far less deadly. WHO says recovery rates are high when pneumonic plague is detected and treated within 24 hours of symptom onset, and that antibiotics are effective when delivered early. Treatment works best before the lungs are badly damaged, which is why health agencies urge people to seek care immediately.

www.who.intwww.who.int
What antibiotics treat plague?

CDC lists gentamicin and fluoroquinolones as first-line treatments in the United States, with streptomycin and tetracyclines such as doxycycline also used. ECDC names streptomycin, gentamicin and tetracyclines as most appropriate. We do not publish doses: drug choice, route and length of treatment are decisions for a clinician.

www.cdc.govwww.ecdc.europa.eu
Is there a vaccine for plague?

There is no plague vaccine on the market in the United States, according to CDC, and WHO does not recommend routine vaccination. WHO says vaccination may be considered for high-risk groups, such as laboratory staff who work with the bacteria and health workers who care for patients with pneumonic plague. CDC notes that new plague vaccines are in development.

www.cdc.govwww.who.int
Does the mpox or smallpox vaccine protect against plague?

No. Mpox and smallpox vaccines target orthopoxviruses, while plague is caused by a bacterium, Yersinia pestis. Protection against one does not carry over to the other. WHO's plague guidance discusses vaccination only for plague-specific high-risk groups, not mpox or smallpox products.

www.who.intwww.who.intwww.cdc.gov
What is post-exposure prophylaxis for plague?

It is a short course of antibiotics given to people who have been exposed but are not yet ill, to stop an infection developing. CDC describes a seven-day course for close, sustained contact with a person or animal that has pneumonic plague. Health authorities decide who needs it.

www.cdc.govwww.who.int
Should I take antibiotics after contact with someone who has plague?

Only if a health authority or clinician prescribes them. WHO tells people to avoid self-medication with antibiotics and says treatment should be given by medical staff. If you had close contact with a pneumonic plague patient, contact your local health authority, who can assess the exposure and advise you.

www.who.intwww.cdc.gov
Is it safe to travel during a plague investigation?

We cannot give travel advice. WHO publishes general travel guidance and says measures should be proportionate to the public health risk, while national authorities issue country-specific advice. If you are travelling to or from an affected area, check your own government's health advice and tell a doctor about your travel history if you become unwell.
