This fungus exists in mold form in the environment; it produces microscopic fungal spores, particularly in moist soil and in decomposing matter such as wood and leaves.

Brucellosis occurs commonly in areas without effective public health and domestic animal health programs. The biggest risk comes from consuming unpasteurized milk and milk products, which tends to be more common outside of the U.S.A but is also becoming more common all over North America as well.

Candida auris infection is difficult to diagnose, and missed diagnosis may lead to spread. It is difficult to treat, and its multidrug resistance also leads to concern of further transmission. There is a high propensity for outbreaks. All of these factors make C. auris a public health concern.

Congenital syphilis is a sexually transmitted bacterial disease passed from mother to child during pregnancy or birth. When left untreated, syphilis in pregnant women can cause serious health consequences including miscarriage, stillbirth, neonatal death, or birth defects. Congenital syphilis is re-emerging and has risen significantly in recent years. In 2019, for example, there were 53 cases of congenital syphilis, the highest number of cases ever reported in Canada. Case counts have risen significantly since 2019 in the provinces, although numbers for the country as a whole are not yet available.

The Coronavirus disease (COVID-19) is caused by SARS-COV-2 coronavirus, a virus strain never previously identified in humans. The genetic sequence indicates that it is a betacoronavirus, closely linked to the SARS virus. The government of Canada has issued COVID-19 pandemic guidance for the health sector for federal, provincial and territorial health authorities.

Canada has protocols and resources to detect, investigate, and manage Ebola cases if it were ever to appear in the country. As of July 22, 2019 Ebola virus disease in DRC is at level 2 risk due to an outbreak that is only in limited geographic areas

Because there appear to have been relatively few observations and analyses of cases and outbreaks specifically associated with EV-D68, much of the information in this Disease Debrief is based on incomplete information from current and previous reports of outbreaks or has been extrapolated from what has been known about similar viruses. Questions, comments or suggestions would be most appreciated.

Tularemia is a bacterial disease that can infect animals and people. In North America, this disease is found in wild animals which include rodents, rabbits, muskrats and beavers. Humans can become infected by tick and deer fly bites, through skin contact with infected animals, drinking contaminated water, and inhaling contaminated aerosols or agricultural and landscaping dust.

Group A streptococcus (GAS) is responsible for a range of diseases in humans. These diseases include strep throat (acute pharyngitis) and skin and soft tissue infections such impetigo and cellulitis. These can also include rare cases of invasive (serious) illnesses such as necrotizing fasciitis (flesh eating disease) and toxic shock syndrome (TSS).

H5N1 AI is a highly pathogenic avian influenza virus that is easily transmitted between birds and is a zoonotic disease (a disease that transmits from animals to people), but it is not well adapted to mammals. There have been reports of possible limited human-to-human transmission, but there has been no evidence of ongoing transmission between people.

Hand, Foot, and Mouth Disease (HFMD) is a highly contagious disease caused by a virus belonging to Enteroviruses. Symptoms usually include fever, mouth sores, and a skin rash commonly found on the hands and feet.

This debrief will focus on HPS/HCPS as this is most common disease in North America NCCID Disease Debriefs provide Canadian…

Treatment for H. pylori infection involves taking a combination of antibiotics and a proton pump inhibitor (PPI) to reduce the amount of acid in the stomach (acid suppression). Most people do not need to be tested for H. pylori if they do not show signs of infection.

Ignatzschineria indica (I. indica) infection is caused by myiasis, the infection of human tissue by fly larvae. It is transmitted by the larvae (maggots) of flesh flies (Sarcophaginae) and blow flies (Calliphoridae).

Legionellosis is caused by Legionella species, small, gram-negative, aerobic bacilli that are found in natural and man-made environments such as cooling towers, potable water systems, lakes, rivers, and streams. Legionella spp. can also be found in soil.

Legionellosis can manifest as 2 distinct syndromes: Legionnaires’ disease (a form of atypical bacterial pneumonia) and Pontiac fever.

Lyme disease is a bacterial infection caused by Borrelia burgdorferi. It spread through the bite of infected ticks. Ticks attach to any part of the human body but are often found in hard-to-see areas. In most cases, the tick must be attached for at least 24 hours before Lyme disease can be transmitted.

Malaria is a parasitic infection spread to humans by female Anopheles mosquitoes. The single-celled parasites are in the genus Plasmodium. Typically, four kinds of malarial parasites infect humans, Plasmodium falciparum, P. vivax, P. ovale, and P. malariae. P. Knowlesi, a type of malaria that naturally infects macaques in Southeast Asia, may also infect humans, causing malaria that is transmitted from animal to human. 

Marburg virus is the causative agent of Marburg virus disease (MVD) formerly known as Marburg haemorrhagic fever. MVD is a zoonotic infection, transmitted from animals to humans. It is a highly virulent disease that causes hemorrhagic fever with an 88% fatality rate. The virus can spread by human-to-human contact with blood, body fluids and by contact with infected body fluid objects.

A single-stranded enveloped RNA virus causes measles, which is a member of the genus Morbillivirus that belongs to the family of Paramyxoviridae. It is considered a highly contagious viral infection.

Middle East respiratory syndrome (MERS) is a viral respiratory illness that is new to humans, caused by a novel coronavirus (MERS-CoV). It was first identified in Saudi Arabia in 2012 and has since spread to several other countries.

MCR-1 is an acronym for Mobilized Colistin Resistance.  It protects bacteria from a polypeptide antimicrobial called colistin (polymyxin E). The gene responsible has been found in bacteria from food animals, raw meat and human samples.

mpox (formerly Monkeypox) virus is a zoonotic disease, meaning it can be transmitted from animals to humans. Squirrels, Gambian pouched rats, dormice, and non-human primates have been found to be susceptible to monkeypox virus. Monkeypox virus transmission occurs when a person comes into direct or indirect contact with the body fluids or lesion materials of infected animals and humans, including contaminated materials.

Multidrug resistant TB (MDR TB) is a disease caused by any strain of Mycobacterium tuberculosis which is not effectively killed by both isoniazid and rifampin, two of the first-line, safest and most effective anti-TB medications.

The mumps infection is caused by the mumps virus, an enveloped, negative-sense, single stranded RNA virus which belongs to the Rubulavirus genus in the Paramyxoviridae family. Although there are several genotypes, only one distinct serotype of the mumps virus is known. Typically, fever, headache, malaise and muscle aches are followed by characteristic painful swelling (inflammation) of the parotid (salivary) gland on one (more common) or both sides of the face.

Mycoplasma genitalium (M. genitalium, or Mgen) is a small facultative anaerobic bacterium and a risk group 2 pathogen. M. genitalium is sexually transmitted through direct mucosal contact. Infections can be asymptomatic or symptomatic, and evidence has suggested persistent infections do occur.

Noroviruses are the most common cause of acute gastroenteritis (stomach flu) in humans, accounting for more than 60% of cases. It affects people of all ages, but it causes severe acute gastroenteritis in children under the age of five. Norovirus is the most common cause of illness and outbreaks due to contaminated food.

Pertussis, whooping cough, a contagious infection is a serious illness in babies, children, teens and adults and a long one to recover from. Bordetella pertussis attaches to the cilia that line the upper respiratory tract and releases toxins which damage it and cause the airways to swell. Pertussis is primarily a toxin mediated disease.

Polio is a highly contagious, vaccine-preventable disease, most often seen in children under 5 years of age. Transmission of polio is person-to-person, mainly through the fecal-oral route and less frequently via contaminated water or food.

Powassan virus is a tickborne flavivirus that causes Powassan disease. Many people either develop mild, flu-like symptoms or no symptoms at all. The time from tick bite to developing symptoms ranges from 1 week to 1 month. Initial symptoms include fever, headache, vomiting, and weakness. More severe symptoms include confusion, loss of coordination, difficulty speaking, and seizures. In some individuals, it can cause a severe disease such as encephalitis or meningitis.

Respiratory Syncytial Virus (RSV) is a very common virus that causes infections of the respiratory tract. Other than monitoring for symptoms, most used RSV are diagnosed clinically. Most RSV infections go away on their own in 1-2 weeks.

Shigellosis is an acute, invasive, enteric bacterial infection that affects the digestive system. It is caused by a group of bacteria called Shigella. Symptoms may appear within 1–2 days of encountering Shigella.
