Infectious disease consultation focuses on evaluating infections caused by bacteria, viruses, fungi or parasites. Specialist assessment may be needed when an infection is persistent, recurrent, severe or difficult to diagnose. Medical evaluation includes reviewing symptoms, previous treatment, laboratory investigations and risk factors to determine an appropriate management approach.
Fever of unknown origin refers to persistent fever that remains unexplained after an appropriate initial medical assessment. Possible causes include infections, inflammatory diseases and other medical conditions. Evaluation involves reviewing the fever pattern, exposure history, examination findings and targeted investigations rather than performing every available test.
Tropical fevers can occur due to infections such as malaria, dengue, enteric fever and other regionally prevalent illnesses. Symptoms vary and may include fever, headache, fatigue or body pain. Diagnosis depends on the clinical presentation, exposure history and appropriate laboratory tests. Treatment is selected according to the identified or suspected cause.
Dengue is a mosquito-borne viral infection that may cause fever, headache, muscle pain, nausea and rash. Some patients develop warning signs or severe complications requiring hospital monitoring. Management focuses on appropriate hydration, symptom control and careful clinical assessment. Severe abdominal pain, bleeding or circulatory problems require urgent medical care.
Malaria is a parasitic infection transmitted through the bites of infected mosquitoes. It may cause fever, chills, headache and other systemic symptoms. Diagnosis involves appropriate blood testing, and treatment depends on the malaria species, disease severity, local resistance patterns and individual medical factors. Severe malaria requires urgent hospital treatment.
Enteric fever is a bacterial infection commonly caused by Salmonella Typhi or Paratyphi. Symptoms may include persistent fever, abdominal discomfort, headache and digestive disturbances. Evaluation considers exposure history and appropriate microbiological testing. Antibiotic selection should account for susceptibility and resistance patterns because inappropriate treatment can contribute to complications.
Tuberculosis is an infectious disease that commonly affects the lungs but can also involve other organs. Symptoms may include prolonged cough, fever, night sweats and weight loss. Evaluation can involve imaging and microbiological testing. Treatment requires a structured medication regimen, appropriate monitoring and coordination with established tuberculosis care programmes.
Respiratory infections may affect the airways or lungs and can cause cough, fever, breathlessness and chest discomfort. Assessment considers oxygen levels, examination findings and relevant investigations. Treatment depends on whether the cause is bacterial, viral or another condition. Severe pneumonia may require hospital admission and respiratory support.
Recurrent urinary tract infections may cause repeated episodes of painful urination, urgency, fever or other urinary symptoms. Specialist evaluation considers previous urine culture findings, antibiotic exposure and possible contributing medical conditions. Treatment aims to manage confirmed infection appropriately while reducing unnecessary antimicrobial use and identifying reasons for recurrence.
HIV is a viral infection that affects the immune system. Medical assessment may involve confirmatory testing, immune function evaluation and screening for associated infections. Effective long-term management generally includes antiretroviral therapy and regular monitoring. Care should be coordinated with an appropriately trained HIV treatment team.
Viral hepatitis involves inflammation of the liver caused by specific viruses, including hepatitis A, B, C and E. Symptoms may include fatigue, nausea, abdominal discomfort and jaundice. Evaluation involves liver function tests and virus-specific investigations. Treatment and monitoring depend on the virus, severity and individual clinical circumstances.
Antibiotic treatment review evaluates whether an antimicrobial medicine is appropriate for a suspected or confirmed bacterial infection. Assessment considers culture findings, antibiotic susceptibility, previous treatments and possible adverse effects. Specialist input can be valuable for complicated or drug-resistant infections and helps support responsible antimicrobial prescribing.
Sepsis is a potentially life-threatening condition caused by an abnormal response to infection that leads to organ dysfunction. Patients may require urgent antibiotics, investigation of the infection source and support for affected organs. Severe cases need immediate hospital assessment and coordinated management involving emergency medicine and intensive care teams.
Travel-related infections may occur after exposure to contaminated food or water, insect bites or other environmental sources. Assessment includes reviewing travel destinations, timing of symptoms, activities and potential exposures. Appropriate testing and treatment depend on the suspected infection, disease severity and local epidemiological factors.
