• Stay Protected from Bacterial Infections
    and Illnesses

Infectious diseases are a group of diseases caused by microorganisms such as viruses, bacteria, fungi or parasites. Under normal conditions, the immune system of the host works fully and combats the fatal microorganisms, so the symptoms do not develop. If the immune system is compromised, the infectious agent overpowers the immune system of the host individual and infectious diseases ensue.

The severity of infection depends upon several variables including;

  • The resistance offered by the host organism
  • Pathogenicity of the infectious agent
  • Environmental factors
  • Immunity of the host organism

Infectious diseases can be transmitted from one individual to another or from pets and other animals. They can also be caused by consuming contaminated food or water or exposure to a contaminated environment.

Signs and symptoms depend upon the severity of the condition and type of infection. They include fever, fatigue, allergy, skin rash and other associated problems.

With the advancement of medicine, some of the fatal infectious diseases such as measles, chickenpox, etc can be prevented by vaccination. Good health and hygiene practices can protect you from many serious infectious diseases.

When to See A Doctor?

Immediately seek medical assistance or consult a health care physician if you have any of the following symptoms;

  • If you have been bitten by an animal
  • If you are facing trouble in breathing
  • Coughing for more than a week
  • If you are experiencing a severe headache with fever
  • A rash or swelling in the skin
  • Experiencing sudden vision problems

Risk Factors for Infectious Diseases

Medications like steroids or any other glucocorticoid that suppresses immunity such as anti-rejection drugs for transplantation or while receiving a blood donation

Chronic infections like HIV

Chemotherapy and radiation for cancer

Complications Associated With Infectious Diseases

Infectious diseases can lead to many severe health problems if they are not treated and managed effectively. Infections such as pneumonia, AIDS, and meningitis can become life-threatening and are associated with the long term risk of cancer and cardiovascular diseases. Some of the reported complications are listed below;

  1.   Human papillomavirus is linked with cervical cancer.
  2.   Helicobacter pylori is associated with colon cancer and peptic ulcers.
  3.   Hepatitis B and C can lead to cirrhosis and carcinoma of the liver.

Some infectious agents live in the body of the hosts’ organisms without any symptoms for years and can cause major complications in the future.

How to Prevent Infectious Diseases?

Following are some of the preventive measures against infectious diseases;

  • Wash your hands properly
  • Get vaccinated
  • Practice good hygiene
  • Prepare your food safely and follow the precautionary measures
  • Do not share personal items with anyone

How to diagnose infectious diseases?

Laboratory tests including blood tests, urine tests, throat swab, stool culture, and lumbar puncture, imaging tests including X-rays, computerized tomography, and magnetic resonance imaging.

Treatment of Infectious Diseases

Your primary care physician can prescribe a variety of medicines depending upon the type of infectious agent. The common drugs include antibiotics, antivirals, antifungals, and anti-parasitic medicines.
