Disease caused by Salmonella typhi
Salmonella Typhi
Salmonella typhi is a type of bacteria that is the cause of serious illness known as typhoid fever. It is one of the most life-threatening bacteria found in contaminated food and water. They can cause severe diarrhoea and abdominal pain, which can develop into complications such as intestinal bleeding and organ failure.
The bacteria is spread through contact with faeces, such as from consuming contaminated food and water. Salmonella typhi infects the intestines and can spread to other parts of the body, such as the gallbladder, liver, and blood. Once it infects the bloodstream, it can cause systemic illness, including fever, chills, and headaches.
For people with weakened immune systems, such as those living with HIV or AIDS, the consequences of an infection with Salmonella typhi can be especially serious. In some cases, typhoid fever can be fatal
Signs and Symptoms of Typhoid Fever
The signs and symptoms of Typhoid fever often start gradually and worsen gradually over the course of a week. Examples of common signs and symptoms may include:
- Fever
- Headache
- Loss of appetite
- Fatigue
- Abdominal pain
- Diarrhea or constipation
- Rashes on the skin
- Enlarged lymph nodes
Treatment for Typhoid Fever
Typhoid fever is treated with antibiotics, such as amoxicillin or ciprofloxacin. Treatment usually lasts for seven to 14 days. If left untreated, typhoid fever can lead to life-threatening complications and may even be fatal. It is important to consult with your healthcare provider if you experience any signs and symptoms of typhoid fever.
Preventing Typhoid Fever
The best way to prevent typhoid fever is to practice good hygiene and take measures to protect yourself from contaminated food and water. Be sure to always:
- Wash your hands with soap and water before and after eating
- Avoid drinking water that may be contaminated from streams, ponds, or lakes
- Only drink bottled or boiled water
- Avoid eating raw or undercooked foods
- Be aware of the risk of food or water contamination when travelling
In addition to these preventive measures, it is important to be aware of a person’s risk of contracting Salmonella typhi, especially if they are travelling to countries where the incidence of typhoid fever is higher.
