Infectious disease consultation involves evaluating suspected or confirmed infections caused by bacteria, viruses, fungi and other microorganisms. Specialists review symptoms, medical history, examination findings and relevant laboratory investigations. Additional tests may be recommended to identify the underlying organism or infection source. Treatment is selected according to diagnosis, illness severity and individual patient factors.
Fever of unknown origin refers to a persistent fever that remains unexplained after appropriate initial medical evaluation. Possible causes include infections, inflammatory diseases and other medical conditions. Investigation may involve blood tests, cultures, imaging and specialist assessment. Treatment depends on identifying the underlying cause rather than using antibiotics without a clear clinical indication.
Dengue is a viral illness transmitted by infected mosquitoes. Symptoms may include high fever, severe body pain, headache, nausea and rash. Management focuses on hydration, symptom relief and monitoring for warning signs such as bleeding, abdominal pain or circulatory complications. Severe dengue requires urgent hospital assessment and appropriate supportive treatment.
Malaria is a parasitic infection transmitted by infected Anopheles mosquitoes. Patients may experience fever, chills, headache and weakness. Diagnosis generally requires blood testing to identify the malaria parasite. Antimalarial treatment depends on the parasite species, disease severity, regional resistance patterns and patient characteristics. Severe malaria requires urgent specialist and hospital-based care.
Typhoid fever is a bacterial infection commonly spread through contaminated food or water. Symptoms may include prolonged fever, abdominal discomfort, headache and digestive problems. Diagnosis can involve blood cultures and other appropriate investigations. Treatment includes suitable antibiotics selected according to clinical guidance and resistance patterns, along with hydration and monitoring for complications.
Leptospirosis is a bacterial infection that can occur after contact with water or soil contaminated by infected animal urine. Symptoms may include fever, muscle pain, headache and jaundice. Severe cases can affect the kidneys, liver or lungs. Early medical evaluation and appropriate antibiotic treatment are important when infection is suspected.
Tuberculosis is an infection caused by Mycobacterium tuberculosis, most commonly affecting the lungs but sometimes involving other organs. Symptoms can include persistent cough, fever, weight loss and night sweats. Diagnosis requires appropriate microbiological and imaging investigations. Treatment involves a recommended combination of anti-tuberculosis medicines with adherence monitoring and assessment for drug resistance.
HIV is a viral infection that affects the immune system. Appropriate care includes confirmatory testing, clinical assessment, antiretroviral therapy and ongoing monitoring of viral load and immune health. Treatment helps control viral replication and reduces the risk of complications. Management may also involve screening for associated infections and providing preventive health guidance.
Hepatitis B and C are viral infections that can affect the liver and sometimes lead to chronic inflammation or liver damage. Assessment includes viral testing, liver function evaluation and determining the stage of infection. Treatment depends on the virus, liver condition and individual clinical factors. Specialist follow-up helps monitor liver health and treatment response.
Pneumonia is an infection or inflammation affecting the air sacs of the lungs. Symptoms may include cough, fever, chest discomfort and difficulty breathing. Evaluation can involve physical examination, oxygen measurement, chest imaging and selected laboratory tests. Treatment depends on whether the cause is bacterial, viral or another condition and on illness severity.
Urinary tract infections occur when microorganisms infect parts of the urinary system, including the bladder or kidneys. Common symptoms include burning urination, increased urinary frequency and lower abdominal discomfort. Complicated infections may cause fever or flank pain. Treatment depends on clinical assessment, urine testing when indicated and appropriate antimicrobial selection.
Drug-resistant bacterial infections occur when bacteria develop resistance to one or more antimicrobial medicines. Such infections can be more difficult to treat and may require specialised testing and carefully selected therapies. Management includes reviewing culture and sensitivity results, infection severity, organ function and potential medication effects. Infection prevention measures may also be necessary.
Fungal infections can affect the skin, lungs, bloodstream or other organs depending on the organism and the patient's immune status. Some infections are mild, while invasive fungal diseases may become serious. Diagnosis can involve laboratory tests, cultures, imaging or tissue examination. Antifungal treatment is selected according to the identified organism and clinical circumstances.
Patients with weakened immune systems may develop infections that are unusually severe, persistent or caused by opportunistic organisms. Immune suppression may result from certain diseases, medications or medical treatments. Evaluation can require specialised microbiological testing and imaging. Management focuses on prompt diagnosis, suitable antimicrobial therapy and coordination with other treating specialists.
Antimicrobial therapy review helps determine whether antibiotics or antifungal medicines are needed and whether the selected treatment is appropriate. Assessment considers the suspected infection, microbiology findings, local resistance patterns, allergies and organ function. Responsible antimicrobial prescribing aims to treat infection effectively while reducing unnecessary medicine exposure and the development of resistance.
Internal medicine focuses on evaluating and managing medical conditions affecting adults, including acute illnesses and multiple coexisting health problems. Consultation may involve reviewing symptoms, medical history, medications, examination findings and laboratory results. Internists coordinate diagnostic evaluation and treatment, referring patients to other specialists when specific conditions require additional expertise or procedures.
