Recent Coronavirus Outbreaks

Several notable coronavirus outbreaks have taken place in the last 20 years. These include:

• SARS-CoV – First reported in February 2003, SARS spread to over 20 countries before it was contained. No cases have been reported since 2004.
• MERS-CoV – Primarily found in the Middle East, especially around the Arabian Peninsula, MERS was first identified in 2012. Since then, isolated travel-related cases have been reported globally, including in the United States and Canada. Transmission is generally associated with contact with animals, especially camels.
• COVID-19 – Found in Wuhan, Hubei Province in China, this virus has spread globally with 115 million cases and 2.5 million deaths.

How Do Coronaviruses Spread?

Human coronaviruses spread similarly to the flu. Transmission is most common in the fall or winter, but can happen in any time of year. Infection usually occurs through:

• Air by coughing or sneezing
• Close personal contact, like shaking hands
• Touching an object with the virus on it and then touching eyes, nose or mouth before washing hands
• In rare cases, fecal contamination

Young children are most likely to get infected. The viruses pose an added threat to young children, seniors and the immunocompromised.

What Are the Symptoms of a Coronavirus?

Symptoms of coronaviruses can vary slightly from strain to strain. But, generally common symptoms include: fever, dry cough, mild breathing difficulties, gastrointestinal issues, diarrhea and general body aches.

More severe symptoms can range from high fever and pneumonia to kidney failure and death. Severe symptoms are uncommon and account for a small percentage of overall cases.

COVID-19 is the most common coronavirus at this time. Other viruses, like MERS, are most common among travellers to regions where the virus is present.

How Is a Coronavirus Treated?

There is no coronavirus-specific treatment available at this time. Most people infected will recover on their own. But, there are some things used to reduce symptoms:

• Pain relievers
• Humidifiers (to help with sore throat and cough)
• Staying hydrated
• Resting at home

More severe symptoms, like pneumonia, may require more specialized care. If you believe you have symptoms of a coronavirus, contact a healthcare professional such as a primary care physician.

Where are Coronaviruses Found?

COVID-19 is present globally, precautions like wearing a mask, social distancing and vaccination is highly important to prevent spread.

Other coronaviruses do pose a limited risk in some regions. MERS is common in the Middle East, but has previously spread in isolated pockets to the United Kingdom and South Korea.

What Should I Do If I’m Traveling to a Region with Coronavirus?

Various countries have put COVID-19 restrictions in place to protect individuals from the virus. This includes proof of a negative test at entry, entry restrictions and, soon, vaccination requirements.

There are currently no restrictions related to other forms of coronavirus. But, travellers are advised to take precautions if they are going to a region with a virus. These include:

• Avoid contact with sick individuals
• Avoid animals, animal markets and uncooked animal products
• Wash hands regularly with soap and water, use hand sanitizers as well

Older individuals or the immunocompromised should consult a healthcare provider before travelling to a region with coronavirus.

Most countries have put health screening checkpoints in place to see if individuals travelling from affected regions may be infected.

How Can I Prevent Coronavirus Infection at Home?

Vaccination is the best form of protections against COVID-19. But, the PHAC continues to recommend the following measures even after vaccination to avoid further spread of the virus:

• Regularly wash hands with soap and warm water for at least 20 seconds
• Avoid touching your mouth, eyes and face
• Avoid going to public places or coming in contact with people who may be infected
• When going outside the house, wear a mask or shield that covers the nose and mouth
• Regularly sanitize high-touch items such as mobile devices, door knobs, light switches, etc.

If you will be traveling to a region with a coronavirus, consult with a travel health specialist at your local Passport Health for additional information and advice specific to your trip. Call or book your appointment online today.
