Significant dog bites affect tens of millions of people globally each year, and cases of human infection following exposure to C. canimorsus have been observed worldwide. [7] It is estimated that 2% of the U.S. population, 4.5–4.7 million people, are bitten by dogs each year.
C. canimorsus and C. cynodegmi are commonly transmitted by dog bites and known to cause sepsis, potentially complicated by thrombotic thrombocytopenic purpura and hemolytic uremic syndrome, in immunocompromised patients. [8] Other complications from infection can include heart attack, kidney failure, gangrene and amputation of limbs. [9]
Over half of dog bite injuries occur at home with familiar dogs and having a dog in the household is linked to a higher likelihood of being bitten than not having a dog. As the number of dogs in the home increases, so does the likelihood of being bitten. [33] Dog bites may transmit zoonotic infections, which may also result in illness or death.
In humans, P. multocida is the most common cause of wound infections after dog or cat bites. The infection usually shows as soft tissue inflammation within 24 hours. High leukocyte and neutrophil counts are typically observed, leading to an inflammatory reaction at the infection site (generally a diffuse, localized cellulitis). [8]
Thankfully, chigger bites don't cause diseases like tick bites can, Levoska says. ... When ants bite humans, it grabs the skin and also sprays a compound called formic acid, Frye explains. Ant ...
Globally, dogs are the most common animal involved. [1] In countries where dogs commonly have the disease, more than 99% of rabies cases in humans are the direct result of dog bites. [11] In the Americas, bat bites are the most common source of rabies infections in humans, and less than 5% of cases are from dogs.
P. canis usually does not affect humans [25] but may be transmitted from animals to humans through animal bites, scratches, or licking over wounds. [7] [22] However, some patients developed infections without any scratches and puncture wounds. [26] In one case, a patient exposed to rabbit secretions was infected with P. canis. [20]
Two-thirds of bite injuries in humans are suffered by children aged ten and younger. [6] Up to three-fourths of dog bites happen to those younger than 20 years-old. In the United States, the costs associated with dog bites are estimated to be more than $1 billion annually. The age groups that suffer most from dog bites are children 5 to 9 years ...
