Prevention

Washing the hands frequently can help to prevent strep throat.

Exposure to infected people should also be avoided. In order to prevent transmission of the disease within households, consult a doctor if any family member suddenly develops a sore throat (especially if it is accompanied by fever).

Boosting the immune system is also important to help prevent the development of strep throat. Vitamin C and zinc are often recommended for this purpose, as are goldenseal, echinacea, and garlic.

Definition

Strep throat is a contagious infection caused by the bacterium Streptococcus pyogenes.

Description

Strep throat primarily affects children, especially those between the ages of five and 15. Adults whose immune systems have been weakened by stress or other infections are also at risk. Most sore throats are associated with viral infections such as the common cold or the flu. Strep throat is responsible in only about 10%-15% of cases. Many people carry Streptococcus pyogenes in their systems without even knowing it. It can survive in the lining of the throat or nose for years without producing symptoms. Almost 20% of people in general good health may be harboring this bacterium unsuspectingly, according to one statistic.

Definition

Stress is an individual’s physical and mental reaction to environmental demands or pressures.

Description

When stress was first studied, the term was used to denote both the causes and the experienced effects of these pressures. More recently, however, the word stressor has been used for the stimulus that provokes a stress response. One recurrent disagreement among researchers concerns the definition of stress in humans. Is it primarily an external response that can be measured by changes in glandular secretions, skin reactions, and other physical functions, or is it an internal interpretation of, or reaction to, a stressor; or is it both?

Prevention

To prevent sunburn, everyone over the age of six months should use a water-resistant sunscreen with a sun protective factor (SPF) of at least 15. Apply at least an ounce of sunscreen 15-30 minutes before going outside.

It should be reapplied every two hours (more often after swimming). Babies should be kept completely out of the sun for the first six months of life, because their skin is thinner than the skin of older children. Sunscreens have not been approved for infants.

Definition

Glaucoma is a slowly progressive eye condition that causes damage to the optic nerve. It is the leading cause of blindness among African-Americans and older adults in the United States. Because there are usually no symptoms early on in the disease, about half of the people with glaucoma do not even know they have it.
