Infectious disease specialists treat almost all diseases caused by microorganisms. Some of the most common ones are urinary tract infections (UTIs), HIV/AIDS, pneumonia, tuberculosis, and tropical diseases like malaria.

You may be referred to an ID doctor by your physician if your infection is difficult to diagnose, your infections are resistant to treatments like antibiotics, you have signs of high fever and infection, your illness is because of your travel history, and you are diagnosed with HIV/AIDs or Hepatitis B and C.

ID specialists may recommend you to get a couple of tests done to diagnose the type of infection. Some of these tests are blood tests, microscopy, cultures and sensitivity of blood, urine, sputum, stool, wound swab, and joint fluid. Sometimes you may also be asked to get imaging tests such as X-rays, ultrasound, MRI scans, and CT scans done.
