What is plague?
Plague is a disease caused by the bacteria Yersinia pestis. This bacteria is usually found in small animals (including rats, squirrels and other rodents) and their fleas.
You can become infected with plague through:
the bite of a flea infected with the plague bacteria
direct contact with infectious tissues or fluids while handling an animal or human that is sick with or that has died from plague
breathing of respiratory droplets from an animal or human with pneumonic plague.
There are three types of plague:
Bubonic plague is the most common form of plague. Infection of the lymph nodes by the plague bacteria (referred to as buboes) causes them to swell and become painful. This form of plague usually occurs from bites of infected fleas.
Septicemic plague occurs when the infection spreads through the blood. It can cause bleeding, and tissue to turn black, especially on fingers, toes, and the nose. This form results from bites of infected fleas or from handling infected animals.
Pneumonic plagueis the most serious form of plague. Pneumonic plague is caused by breathing in droplets from the cough of an infected person or animal. It is also caused by untreated bubonic or septicemic plague bacteria that spread to the lungs. It is the only form of plague that can be spread from person to person via droplets in the air.
What are the symptoms of plague?
Symptoms of plague can appear one to seven days after contact and they can vary depending on the form of plague. They are usually flu-like and can include the following:
weakness and headache
shortness of breath, chest pain, cough and bloody/watery mucous
painful and swollen lymph nodes (buboes)
diarrhea, abdominal pain
Is there a vaccine for plague?
There is no vaccine available for travellers.
All forms of plague can be effectively treated with antibiotics if diagnosed early. If left untreated it can progress rapidly to death.
What is the situation in Madagascar?
Cases of bubonic plague are reported in Madagascar nearly every year between September and April.
Currently, Madagascar is experiencing a serious outbreak of pneumonic plague which can be spread from person to person. An increased number of pneumonic plague and bubonic plague are being reported throughout the country, including areas that do not usually experience plague. The most affected areas are Antananarivo (the capital), Toamasina (the port city) and Faratsiho (rural district). For more information, see the plague outbreak situation report. This report includes a map showing where in Madagascar cases of plague are being reported. For more information see the updates on plague.
The World Health Organization and Madagascar’s Ministry of Public Health are rapidly responding to this situation. To help prevent international spread of plague, they have implemented exit screening for those departing the country.
Exit screening varies from country to country and occurs at airport, ports, and border crossings. This may include:
completing a health questionnaire
testing for the presence of fever
assessment of symptoms
Cooperation with exit screening helps to contain a disease, and prevent a larger epidemic.
How can you protect yourself from plague?
Before you travel you should:
Consult a health care provider or visit a travel health clinic preferably six weeks before you travel.
During your trip:
Protect yourself from flea bites while travelling to Madagascar.
Use insect repellent on exposed skin
Cover up: wear light-coloured, long–sleeved shirts and long pants
Avoid contact with:
rodent nests and burrows as these could contain fleas
sick or dead animals.
close contact with persons who are sick or persons suspected of infection with pneumonic plague.
crowded areas where pneumonic plague have been recently reported
bodies of people who died of plague or unkown illnesses, including during funeral or burial rituals.
If you have had contact with someone with pneumonic plague, you should immediately contact a health care provider. You may need antibiotics to prevent infection.
Wash your hands frequently.
Wash your hands often with soap and water for at least 20 seconds.
Use alcohol-based hand sanitizer if soap and water are not available. Keep a bottle with you when you travel.
Health care workers that may come into contact with someone with pneumonic plague:
should practise strict infection prevention and control measures including the appropriate use of personal protective equipment
take antibiotics to prevent infection
While you are in Madagascar, or returning to Canada:
Monitor your health
If you develop symptoms of plague:
See a health care provider immediately during your trip, or after you return home. Tell them about your symtoms and about your travel to Madagascar.
Tell a flight attendant or border services officer when entering Canada. They will notify a quarantine officer who can assess the symptoms.
Follow any exit screening protocols where required.
Stop the spread of germs
You should not travel if you are ill, or have been in contact with someone who shows symptoms or has been diagnosed with plague.
Avoid close contact with other people. Practise proper cough and sneeze etiquette – cover your mouth and nose with your arm, not your hand.
