Common mistakes, and the whole course on one page

Ten mistakes.

1. "Plague is history." It is a disease of wild rodents that still reaches people every year.
2. "Plague is a death sentence." It is a bacterial infection that antibiotics cure when they are started early.
3. "It is only flu. I will see how I feel on Monday." With plague a day is the difference. Sudden fever after an exposure means a doctor today.
4. "I will take the antibiotics I have at home." The wrong medicine or the wrong dose does not cure plague; it hides it.
5. "I will not mention the trip, or the animal." The history of exposure is what makes a doctor think of plague at all.
6. "There are dead rats. I will throw them out and put down poison." Report them. Do not touch them with bare hands. Fleas first, rodents second.
7. "I will just wash the body myself." The dead can infect those who prepare them.
8. "A mask protects me from bubonic plague." Bubonic plague comes from a flea. Masks belong to the pneumonic form.
9. "There is a vaccine; I will get it before the trip." There is none for the public.
10. "Everything in the house has to be disinfected." The bacterium is fragile. Deal with the fleas, and with anything soiled.

The numbers.

• Incubation: 1 to 7 days overall. Bubonic usually 2 to 6 days. Pneumonic 1 to 3 days, sometimes less than 24 hours.
• Doctors count back 10 days when they ask about exposure.
• Pneumonic plague: treatment within 24 hours of the first symptoms.
• A patient with pneumonic plague is contagious from the first symptom until 48 hours of effective antibiotics.
• Close contact: within 2 metres.
• Preventive antibiotics after an exposure: 7 days.
• Treatment: 10 to 14 days.

The signs.

• Every form: a sudden high fever, chills, headache, weakness.
• Bubonic: a very painful swollen node in the groin, the armpit or the neck.
• Pneumonic: a cough, chest pain, shortness of breath, blood in the sputum — worse by the hour.
• Septicaemic: bleeding into the skin; fingers, toes or the nose turning black.

What to do.

• Sudden fever after an exposure: medical help at once. 112 across the European Union; the local emergency number elsewhere.
• Say where you have been and what you touched.
• If you are coughing: a mask, and 2 metres.
• No antibiotics of your own. Do not squeeze the swelling.
• If you were close to a patient: tell the health service, and take the preventive course you are given.

What protects.

• Against fleas: repellent, covered legs, flea control for pets.
• Against animals: hands off the dead and the sick; gloves for skinning.
• Against rodents: food shut away, holes sealed, rubbish covered.
• Against the cough: distance, a mask on the sick person, fresh air.

One sentence to keep. Plague is rare, it is fast, and it is curable — and the only part of that which depends on you is how soon you ask for help.

What this is not. Reading, not medical advice. In an emergency follow the instructions of the health authority and the emergency services where you are.
