From the Research
Canine cough, also known as kennel cough, generally does not transmit to humans. The primary pathogens that cause canine cough, including Bordetella bronchiseptica and canine parainfluenza virus, are species-specific and rarely infect people 1. However, in extremely rare cases, individuals with severely compromised immune systems (such as those undergoing chemotherapy, with HIV/AIDS, or who have had organ transplants) might be susceptible to Bordetella bronchiseptica infection from an infected dog.
Key Points to Consider
- Healthy humans have natural immunity against these canine-specific pathogens because their respiratory tract defenses and immune systems effectively prevent infection.
- If you're concerned about a dog with canine cough in your household, basic hygiene practices like handwashing after handling the dog and avoiding face licking are sufficient precautions.
- The disease spreads efficiently between dogs through respiratory droplets and direct contact, but the species barrier prevents routine transmission to humans due to differences in cellular receptors and immune responses between dogs and people.
Relevant Studies
- A study published in 2019 discussed the complexity of cough pathophysiology and diagnostic strategies used to uncover underlying etiology of cough in small animal patients 2.
- Another study published in 2022 reported the use of sub-antimicrobial dosage of doxycycline for the chronic treatment of bronchiectasis in a dog, highlighting the anti-inflammatory effects of doxycycline 3.
Precautions and Prevention
- While the risk of transmission from dogs to humans is low, it's essential to take precautions to prevent the spread of disease, especially for individuals with compromised immune systems.
- Basic hygiene practices, such as handwashing and avoiding face licking, can help prevent the transmission of disease.
- It's also important to note that other pathogens, such as Capnocytophaga canimorsus, can be transmitted through dog bites and pose a serious threat to human health, especially for individuals with certain underlying conditions 4.
