DISEASES AND ILLNESSES 

Infectious and noninfectious diseases

Infectious diseases, such as common colds, are caused by harmful organisms called pathogens entering our body.

Examples Different kinds of pathogens cause different kinds of diseases. Here are some example diseases caused by each type of pathogen: Viruses - Viruses are extremely small and consists of DNA with a protective coating of protein. Diseases caused by viruses include influenza, the common cold, measles, yellow fever, and hepatitis. Bacteria - Bacteria are small microorganisms. They can cause diseases such as tuberculosis, cholera, typhoid fever, and tetanus. Parasites - Parasites are organisms that live off their hosts. Some parasitic diseases include malaria, sleeping sickness, and scabies. Fungi - Fungi are microorganisms such as yeasts and molds. They can cause diseases such as fungal meningitis, ringworm, and thrush.

The most common pathogens are bacteria and viruses. Other microorganisms, such as some kinds of fungi and protists, can also cause diseases.

Non-infectious diseases, such as diabetes, are not caused by organisms. They are caused by different factors and cannot be spread from person to person.

 A healthy lifestyle helps prevent diseases. This includes a healthy diet, exercise, regular check-ups, and saying no to drugs and alcohol and an excessive use of video games.

ADVANCES IN MEDICINE

One way of developing immunity to some infectious diseases is through vaccination.

 Doctors and physicians use a variety of diagnostic techniques to identify an illness, such as X-rays, electrocardiographs, blood tests, ultrasound scans and CT scans.

 

 There have been lots of scientific advances in the treatment of illnesses, such as antibiotics, which are used to treat infections caused by bacteria. 

 

Since the invention of anaesthesia in 1800, there have been lots of advances in surgery and in other medical fields.
