There is currently no clear evidence that hamsters can contract diseases from humans, but there is a theoretical risk of cross-infection. Here’s an analysis of key information:
I. Main Risk Directions
Potential Reverse Transmission
Human respiratory viruses (such as the flu) could theoretically spread to hamsters via droplets, though actual cases are extremely rare.
There is a hypothetical risk of transmission for intestinal viruses like hand, foot, and mouth disease through contact. It’s important to avoid sneezing directly at hamsters or touching them without washing your hands first.
Environmental Vector Transmission
Staphylococcus aureus carried on human skin may contaminate hamsters’ water bottles or food bowls through touch.
Shared cleaning tools (such as unsterilized cage brushes) can serve as a pathway for germ transmission.
II. Preventive Measures
Wash hands before and after contact: Especially when suffering from a cold or diarrhea.
Isolation management: Reduce interaction with hamsters when you’re sick.
Environmental disinfection: Scald cage accessories with hot water (above 60°C) weekly.
III. Special Considerations
People with weakened immune systems (such as chemotherapy patients) should avoid close contact with hamsters to reduce the risk of bidirectional infection.
If a hamster shows abnormal symptoms (such as sneezing or diarrhea), isolate it for observation and seek veterinary care promptly.
It’s worth noting that existing research focuses more on cases of hamsters transmitting diseases to humans, with fewer empirical studies on reverse transmission. Maintaining basic hygiene practices is sufficient to effectively control the risks.
