Aedes aegypti mosquito

The Aedes aegypti mosquito is a tropical mosquito that is part of the Aedes species. It is capable of transmitting several viruses, including Zika, dengue, chikungunya, and yellow fever. These mosquitoes are small and have a black and white pattern on their legs and other parts of the body.

Aedes albopictus mosquito

The Aedes albopictus mosquito is a tropical mosquito that is part of the Aedes species which is capable of transmitting Zika virus. Although this species of mosquito, also known as the Asian tiger mosquito, is capable of transmitting viruses including Zika, it is not the species that is responsible for the majority of human cases of Zika virus infection in the Caribbean, South America and Florida. That species is the Aedes aegypti mosquito.

Amebiasis

Amebiasis is an infection caused by a parasite, called Entamoeba histolytica.  It lives in the feces (poop) of a person.  Most infections occur in a person’s stomach and intestines (gastrointestinal tract).  In some people, the disease may occur in the liver, lungs, skin, and other parts of the body.

Animal Bite

If you’re bitten or scratched by a domestic or wild animal, seek immediate medical attention and report the incident to us.

Anthrax

Anthrax is an infection caused by the bacterium Bacillus anthracis.

Asbestos

Asbestos is the name of a group of minerals that are shaped like long, thin fibres that were used to make products strong, long-lasting and fire-resistant.

Asian tiger mosquito

The Aedes albopictus mosquito is a tropical mosquito that is part of the Aedes species which is capable of transmitting Zika virus. Although this species of mosquito, also known as the Asian tiger mosquito, is capable of transmitting viruses including Zika, it is not the species that is responsible for the majority of human cases of Zika virus infection in the Caribbean, South America and Florida. That species is the Aedes aegypti mosquito.

Asthma

Asthma is a chronic (long-term) disease in which a person’s airways are inflamed, making it difficult to breathe. The airways become more inflamed when “triggers” are inhaled, which can cause them to produce more mucous and may also cause the muscles around the airway to tighten.

Asthma in the Classroom

The following information will provide an overview of key facts about asthma, and will outline helpful tips for managing students in the classroom with an asthma diagnosis.

Bed Bugs

Bed bugs are wingless, red-brown, blood sucking insects. They’re oval shaped and live four months to one year. They can survive for long periods without a blood meal. Their eggs are whitish, pear-shaped, and approximately the size of a pinhead.

Blue-Green Algae Bloom

Blue-green algae are microscopic bacteria that occur naturally in fresh water lakes. In warm weather, with the right nutrients and low wind, they can form a large mass called a bloom. Residents and visitors are urged to take a cautious approach, monitor the situation, and protect themselves from potential health risks.

Botulism

Botulism is a serious form of food poisoning that can cause death and paralysis.

Brucellosis

Brucellosis is a bacterial disease that occurs most often in people who work with livestock or in slaughterhouses, or who consume unpasteurized dairy products.

Campylobacter

Campylobacter refers to a group of bacteria that's commonly found in the intestines of animals, including poultry, wild birds, swine, cattle, rodents, and household pets. Campylobacter jejuni and Campylobacter coli are the two species that most often infect humans, causing an illness.

Chickenpox

Chickenpox is a very contagious and common illness with rash and fever caused by the varicella-zoster virus. Chickenpox illness usually lasts about 5 to 10 days and is usually a mild infection, however, it can be life-threatening to some.

Chikungunya Virus

Chikungunya is a disease spread to humans by the bite of an infected mosquito. The disease typically causes high grade fever combined with arthritis-like joint pains.

Chlamydia

Chlamydia is a sexually transmitted bacteria that is spread by sexual contact with an infected person.

Cholera

Cholera is an intestinal infection caused by bacteria. The bacteria can be found in water or food that has been contaminated with stool (poop) from a person who is infected with cholera. In Ontario, an average of one case per year is reported and all cases have been exposed to cholera in another country while travelling. Places in the world with poor sanitation, poor water treatment and inadequate hygiene are more likely to have cholera.

Cold-related Injury

Cold weather can be harmful to your health. While the health risks related to cold are higher for certain groups (such as people who work outdoors, people with pre-existing heart conditions or respiratory illnesses, older adults, infants, young children, and those who are experiencing homelessness), everyone is potentially at risk.

Common Cold

The common cold is a virus that infects the upper respiratory tract. There are over 100 viruses that can cause the common cold. These viruses are very contagious and exist throughout all four seasons.

Concussion

A concussion is a brain injury. It’s the result of a strong force being passed on directly or indirectly to the head or the body that shakes the brain within the skull.

Cryptosporidiosis

Cryptosporidium is a parasite that causes diarrhea in humans and animals. When a person gets sick, the infection is called cryptosporidiosis. Once infected, the parasite lives in the intestine and passes in the stool. Both the disease and the parasite are commonly known as “crypto.”

Cyclosporiasis

Cyclospora is a parasite that causes an illness in the intestines called cyclosporiasis.

Diphtheria

Diphtheria is a bacterium that releases a toxin into the infected person’s body. Diphtheria affects the upper respiratory tract. A greyish coloured membrane forms at the back of the throat. The membrane can make it difficult to breathe or swallow.

E. Coli

Escherichia coli, also called E. coli, are bacteria that are often found in the intestines of people and animals. There are different types of E. coli. Some types of E. coli are not harmful, but others like E. coli O157:H7, can make some people very sick. Usually illness is caused by eating contaminated food or water, having contact with someone who is sick with the bacteria, or animals that carry it.

Ebola

Ebola is a severe acute viral illness in humans. Ebola risk is very low in Windsor-Essex. To date, there have not been any cases of Ebola in Canada, and the risk to Ontarians remains low.

Emergency Preparedness

You may not be able to predict when a disaster will happen, but there are ways you can reduce the impact of any emergency you might face.  You can become better prepared to face a range of emergencies by taking a few simple steps:

Enterovirus D68

Enterovirus D68 (EV-D68) is a relatively rare virus with potentially serious risks to some people.

Exposure to potential blood borne infections

This page was developed to help guide you through the 6 to 12 months after an exposure to potential blood borne infections.

Fifth Disease

Fifth disease is caused by the virus Parvovirus B19. Symptoms may begin 4 to 20 days after you are exposed to someone who is infected. It's most contagious before the development of the rash.

Flooding

Floods are a common and widespread natural hazard across Canada, causing extensive damage to property and loss of life. Floods can result from heavy rainfall, sewer backups, severe storms, breaking dams, broken water mains, and thawing of snow and ice. Some floods develop slowly, sometimes over a period of days or weeks. However, flash flooding usually occurs with little or no advance warning.

Giardia

Giardia is a parasite that causes an infection in the intestinal track. Symptoms usually start 3 to 25 days after being exposed to the parasite.

Gonorrhea

Gonorrhea is a sexually transmitted bacteria that is spread by sexual contact with an infected person.

Grippe

Qu'est-ce que la grippe? La grippe est une infection respiratoire d'origine virale.

Haemophilus Influenzae Type b (Hib)

Haemophilus Influenzae (Hi) is caused by a bacterial infection. There are many types or “strains” of it. The sickness can be mild or very serious. If the infection gets into the bloodstream, brain, or other areas where it’s usually not found, it can cause severe infection.

Hand, Foot, and Mouth Disease

Hand, foot, and mouth disease is a common viral illness that usually affects infants and children younger than 5 years, but it can occur at any age.
