A disease is a particular abnormal, pathological condition that affects part or all of an organism. It is often construed as a medical condition associated with specific symptoms and signs. It may be caused by factors originally from an external source, such as infectious disease, or it may be caused by internal dysfunctions, such as autoimmune diseases. In humans, "disease" is often used more broadly to refer to any condition that causes pain, dysfunction, distress, social problems, or death to the person afflicted, or similar problems for those in contact with the person.

Asthma : a chronic disease

The word 'asthma' is derived from the Greek meaning ' panting' or 'labored breathing'.

Asthma, as defined by World Health Organization, is a chronic disease characterized by recurrent attacks of breathlessness and wheezing, which vary in severity and frequency from person to person.

Child skin problems

Wondering what that rash, welt, or bump on your child's skin is? Infection, allergies, and temperature extremes are often behind the skin conditions seen in babies and children -- and many are minor and easily treated.

You can learn to recognize some of the most common conditions -- but remember: always consult a doctor for proper diagnoses and treatment.

Adult skin problems

Is your skin itching, breaking out, covered in a rash, or playing host to strange spots? Skin inflammation, changes in texture or color, and spots may be the result of infection, a chronic skin condition, or contact with an allergen or irritant.

You can learn to recognize common adult skin problems. Yet, while many are minor, they may signal something more serious, so always consult a doctor for proper diagnosis.

Avoid an Asthma Emergency

Asthma can be life-threatening. Watching somebody gasping for breath is a terrifying experience and being well prepared is the best advice.

With severe asthmatics it’s important to have a written programme displayed in a prominent place so everyone knows what to do when an asthma attack occurs. Severe asthmatics are also advised to have oxygen at hand and to get to the emergency service at the local hospital as quickly as possible.
