Infectious Fevers: Diagnosis & Treatment for Typhoid and Dengue

Fever is not a disease in itself, but rather a natural defense mechanism of the body fighting off an infection. In primary care, we categorize fevers based on their duration, pattern, and accompanying symptoms. Infectious fevers like Typhoid and Dengue are common in India and require distinct medical approaches because one is bacterial while the other is viral.

When you present with a fever at Pluxo Health Clinic, our general physician conducts a comprehensive physical evaluation. We check your vital signs, assess your hydration status, and examine your abdomen and skin. This initial clinical assessment helps us narrow down the potential causes and determine the most appropriate diagnostic tests, ensuring you receive targeted care.

Typhoid fever is a systemic bacterial infection caused by Salmonella typhi. In India, it commonly spreads through the consumption of contaminated food and water, particularly in areas with limited access to clean drinking water or poor sanitation. Once ingested, the bacteria multiply in the bloodstream and intestinal tract, leading to a sustained, step-ladder pattern of high fever.

Key symptoms of Typhoid fever include: A sustained high fever that rises gradually over several days Severe headache and extreme physical weakness or fatigue

• Stomach pain, loss of appetite, and either diarrhea or constipation

Because Typhoid is a bacterial infection, it requires appropriate antibiotic therapy prescribed by a qualified general physician. It is vital to complete the full course of antibiotics as directed, even if you start feeling better, to completely eradicate the bacteria and prevent a relapse or the development of antibiotic resistance.

Dengue fever is a viral infection transmitted to humans through the bite of infected Aedes mosquitoes, which typically bite during daylight hours. This condition is highly seasonal, with cases peaking during and after the monsoon. Unlike Typhoid, Dengue is a viral illness, meaning antibiotics are completely ineffective against it, and management relies heavily on supportive care.

Common symptoms of Dengue include: Sudden onset of high-grade fever Severe pain behind the eyes and intense joint and muscle pain (often called 'breakbone fever')

• Skin rashes and persistent nausea or vomiting

While most people recover within a week, some may develop severe Dengue, which can lead to a dangerous drop in blood platelet counts. Warning signs of severe Dengue include persistent abdominal pain, bleeding from the gums or nose, persistent vomiting, and extreme lethargy. If you notice any of these warning signs, consult a doctor immediately.

An accurate diagnosis is the first step toward effective treatment. At Pluxo Health Clinic, we recommend specific blood investigations based on the duration of your fever and clinical presentation. For suspected Typhoid fever, tests like the Typhidot (which detects antibodies) or blood cultures are utilized, especially in the early stages. The Widal test may also be used, though its results require careful interpretation by a medical professional.

For suspected Dengue, we look at: Dengue NS1 Antigen: Highly accurate during the first few days of the fever. Dengue IgM/IgG Antibodies: Useful as the infection progresses.

• Complete Blood Count (CBC): To monitor your white blood cell and platelet counts regularly.

Our general physician will guide you on which tests are necessary and explain the reports in a clear, easy-to-understand manner, avoiding confusing medical jargon.

Preventing infectious fevers involves addressing their root causes. For Typhoid, prevention focuses on consuming boiled or filtered water, washing hands thoroughly before meals, and avoiding raw or uncovered street food. For Dengue, prevention centers on mosquito control, using insect repellents, wearing long-sleeved clothing, and ensuring there is no stagnant water around your home where mosquitoes can breed.

During recovery from either fever, hydration is the single most critical factor. Drinking plenty of fluids, such as oral rehydration solutions (ORS), coconut water, clear soups, and fresh juices, helps prevent dehydration caused by high fever and vomiting.

While most cases can be managed safely at home under the guidance of our general physician, hospitalization may be required if the patient experiences severe dehydration, persistent vomiting, an inability to tolerate oral fluids, or a critically low platelet count. Regular follow-up consultations at Pluxo Health Clinic within 7 days of your initial visit help us monitor these parameters closely to ensure your safe recovery.
