Weil's disease is caused by the icteric phase of leptospirosis which can be spread to humans from infected animals such as rats.
Weil's disease is a severe infection that causes fever, renal failure, jaundice, hemorrhage and respiratory distress and the icteric phase can also involve the CNS, muscles and heart.
All rats and even mice carry disease and the diseases can be spread to humans through contaminated food, feces, scratches and even rat bites.
The diseases that rats can transmit to humans are rat bite fever, hantavirus, leptospirosis, lymphocytic choriomeningitis, salmonella and Tularemia.
The diseases spread by rats to humans can be spread through rat feces, contaminated food and even bites or scratches.
If a rat bites you the rat bite can cause joint and muscle pain and swollen lymph nodes as well as bleeding where you were bitten.
Not only that but if a rat bites you the rat bite can cause rat bite fever which is a bacterial disease that spreads through infected rats and other rodents through a bite or a scratch.
Symptoms of rat bite fever include fever, skin rash, and headache as well as possible joint and muscle pain and or swollen lymph nodes.
Even if the rat bite seems minor, it's always best to see a doctor as soon as possible after the rat bite.
Bites from rats are also prone to turning into potentially serious infections.
You should also get a tetanus shot, especially if it's been more than five years since your last one (or you don't remember the date of your last tetanus shot).
If the rat bite causes a deep puncture or the skin is badly torn and bleeding, apply direct pressure to stop the bleeding and get medical attention right away.
If you develop a fever or other signs of infection swelling, redness, pain, a bad smell or fluid draining from the area see a physician immediately.
