2. The Hidden Danger: Infection Risks
One of the most serious risks after a dog bite is infection. A dog’s mouth contains numerous bacteria that can be easily introduced deep into tissues through a bite wound.
2.1. Bacterial Infections
Bacteria can easily enter the skin through a bite, leading to a localized or systemic infection. Key signs that a wound has become infected include:
- Primary Symptoms: These signs appear at the wound site and include severe pain, increased redness and swelling, warmth in the surrounding skin, and a foul-smelling pus or discharge.
- Systemic Symptoms: If the infection begins to spread throughout the body, a person may develop a fever, experience chills, and notice swelling in the lymph nodes near the injury.
- Serious Complications: Left untreated, a severe infection can lead to dangerous complications such as bone infections (osteomyelitis) or joint infections (septic arthritis).
2.2. Tetanus
Tetanus is a severe and often fatal disease caused by the bacterium Clostridium tetani, which is found in soil and animal waste. These bacteria can enter the body through deep, contaminated wounds like a dog bite. Tetanus attacks the nervous system, causing severe muscle spasms, lockjaw, and paralysis. Because it is so dangerous, keeping tetanus vaccinations up to date is critically important for preventing this risk.
Beyond the immediate trauma and subsequent risk of infection, the effects of a severe dog bite can last a lifetime, impacting both body and mind.
