Infectious Disease

Infectious diseases are illnesses caused by Bacteria, Viruses, Fungi or Parasites that invade the body and cause infection

While many infections are mild and can be effectively treated, some may become severe or life-threatening if not diagnosed and treated properly. Early diagnosis, appropriate treatment and infection prevention play a vital role in improving outcomes

Vulnerability

Who is at Higher Risk?

Certain individuals are more vulnerable to developing serious infections including:

  • Patients admitted to the hospital or intensive care unit (ICU)
  • People with Chronic Kidney Disease (CKD)
  • Dialysis patients
  • Individuals on Immunosuppressants
  • People with diabetes
  • Older adults
Pathology

Common Serious Bacterial Infections

Serious bacterial infections may affect different parts of the body including:

  • Bloodstream Infections (Sepsis) which can lead to Multiple Organ Failure
  • Pneumonia
  • Urinary tract infections (UTIs)
  • Intra-abdominal infections
  • Skin and soft tissue infections
  • Kidney infections

Important Note: Prompt medical attention is important, as these infections can worsen rapidly if left untreated

AMR Overview

What is Antimicrobial Resistance (AMR)?

Sometimes bacteria develop the ability to survive despite treatment with antibiotics. This is known as antimicrobial resistance (AMR). Antibiotic-resistant infections are more difficult to treat and may require specialized medicines and close medical supervision

Antibiotics are essential to slow the spread of antimicrobial resistance

Treatment

Treatment of Serious Infections

Treatment depends on the Type of Infection, the Microorganism causing it and its severity. Your doctor will recommend the most appropriate treatment based on your symptoms, medical history and laboratory test results

Antibiotics

Used to treat bacterial infections. It is important to take antibiotics exactly as prescribed and complete the full course, even if you start feeling better

Antiviral Medications

Used to treat or prevent viral infections, particularly in people with weakened immune systems

Antifungal Medications

Used to treat infections caused by fungi, especially in patients with weak immunity or prolonged hospitalization

Supportive Care

Depending on the severity of the infection, treatment may also include:

  • Intravenous (IV) fluids
  • Oxygen therapy
  • Fever and pain management
  • Nutritional support

Hospital-Based Care

Patients with severe infections may require hospitalization for close monitoring, intravenous medications, or intensive care support until the infection is controlled

Post-Transplant

Infections After Organ Transplant

Patients who undergo an organ transplant need Immunosuppressants to prevent organ rejection. While these medicines are essential, they also weaken the body's natural defenses, increasing the risk of Bacterial, Viral and Fungal Infections

Cytomegalovirus (CMV) Risk

Cytomegalovirus (CMV) is a common virus that usually causes mild or no symptoms in healthy individuals. However, in patients with weakened immune systems—especially kidney transplant recipients—CMV infection can become serious and may affect the transplanted organ or other parts of the body

Preventing Infections After Transplant

Patients who have received an organ transplant can reduce their risk of infection by:

  • Taking Immunosuppressive and preventive medications exactly as prescribed
  • Practicing good hand hygiene
  • Avoiding contact with people who are unwell
  • Attending regular follow-up appointments
  • Reporting fever or signs of infection promptly

Whether it is preventing infections after transplantation or managing serious bacterial and viral infections, early diagnosis and appropriate treatment play a vital role in improving patient outcomes. Working closely with your healthcare team and following the recommended treatment plan can help you recover safely and maintain your overall health
