Squirrel bites or droppings may cause bacterial infections, leptospirosis and salmonella. If squirrels carry fleas or ticks, they can pass them to humans, houses and family pets.
Squirrels are strong biters and can inject bacteria to bone surrounding tissue, which can result in osteomyelitis or septic arthritis. It is important to clean the wound immediately if bitten and seek medical advice to determine whether antibiotics are needed.
Squirrel feces and urine can transmit leptospirosis and salmonella on contact. Leptospirosis is a bacterial infection that feels like a flu at its early stages and can be treated with antibiotics. When not treated, life-threatening symptoms may appear.
Salmonella may begin with vomiting and diarrhea. It is important to seek medical advice promptly and treat the condition to avoid complications.
