A Canadian man was hospitalized after a rat bite in his toilet led to a severe bacterial infection. The incident puzzled doctors due to its rarity, prompting speculation about the origin of the bacteria from the rat's mouth. This highlights the potential health hazards posed by unexpected encounters with rodents in household environments.

76-Year-Old Man Develops Leptospirosis Following Rat Bite Encounter
Following an encounter with a rat in his toilet, a 76-year-old man sought medical attention at a Montreal hospital's emergency department after sustaining finger bites while attempting to remove the rodent. Upon admission, medical staff provided initial wound care and administered a tetanus booster to prevent potential complications arising from the rat bite.
However, despite some improvement in his finger wounds, the patient returned to the hospital approximately 18 days later due to persistent symptoms, including fever, headaches, and abdominal pain.
Despite the observed progress in his finger wounds, his overall health had deteriorated, as evidenced by low blood pressure and an elevated heart rate.
Moreover, subsequent blood tests revealed signs of kidney damage and a decreased platelet count, suggesting the possibility of multi-organ dysfunction and sepsis-a severe immune response to infection. Consequently, the patient was admitted to the intensive care unit for close monitoring and further evaluation of his condition.
Medical professionals conducted thorough investigations to determine the underlying cause of the patient's illness, collecting and analyzing blood and urine samples. The results of these analyses, published in the Canadian Medical Association Journal in January, confirmed the presence of leptospirosis-an infectious disease transmitted through exposure to contaminated water or soil.
This diagnosis not only elucidated the origin of the individual's illness but also underscored the importance of timely medical intervention in cases of uncommon infections.
The man received antibiotics and treatments for kidney damage and low platelet levels. His symptoms improved, leading to discharge from the ICU. The authors noted that rats infected with Leptospira shed bacteria in urine, suggesting the bacteria entered the man's body through bite wounds, a less common transmission route.

Leptospirosis: A Global Threat with Diverse Symptoms and Transmission Risks
Leptospirosis, caused by the Leptospira bacteria, affects both humans and animals, presenting a wide range of symptoms from mild to severe or even asymptomatic. If untreated, it can lead to kidney damage, meningitis, liver failure, respiratory distress, and potentially death.
Worldwide, it stands as the predominant zoonotic infection, with an annual incidence surpassing one million cases and leading to nearly 60,000 fatalities. Symptoms typically arise within 5 to 14 days following infection and can often resemble those of prevalent illnesses like influenza or dengue fever.
Treatment with antibiotics is usually effective, but severe cases can result in multi-organ dysfunction and a mortality rate ranging from 5% to 15%.
Transmission happens through contact with infected animals' urine, soil, or water, with farm animals and pets acting as carriers. Risks may rise during disasters, increasing exposure to contaminated areas. Contaminated water consumption directly contributes to disease spread. The bacterium enters through broken skin or mucous membranes, and while rare, person-to-person transmission is possible.
Notably, infected animals may show no symptoms, complicating efforts to detect and manage outbreaks. Understanding the disease's transmission routes and promptly administering antibiotics are crucial in mitigating leptospirosis outbreaks and reducing associated morbidity and mortality.
