Herpes
There are two simple herpes viruses (VHS), which is presented in the form of cold or genital herpes. It has no cure, it is very contagious and is a growing global problem.
The herpes virus is so easily transmitted that there are already more than 3,700 million people under 50 infected around the world, which is equivalent to almost two-thirds of the global population (67%).
The figure corresponds to those affected by the VHS-1 virus, which mainly causes labial or orsolabial herpes and & ldquo; it is transmitted by mouth-to-mouth contact and, in some cases, by orogenital & rdquo contact;, according to the World Organization of the Health (WHO).
In total, 417 million people between 15 and 49 years old worldwide are infected by VHS-2.
Infected by the VHS-1 virus on the American continent
178 million women 49% of the female population.
142 million men 39% of the male population.
Sex education
The WHO warns that, despite the increase in hygiene conditions in developed countries, & ldquo; there is increasing risk that the adolescent population contract the genital contact virus “.
& Ldquo; Access to education and information on both types of viruses is essential to protect the health of young people, before they are sexually active & rdquo, explained Marleen Temmermean, director of the Department of Reproductive Health and Research of the WHO.
& ldquo; The new data highlights the need for countries to improve the development of statistics on both types of herpes “.
But how big is the number of affected in the world?
Only in the American continent, there are 178 million women and 142 million men affected by the VHS-1 virus.
Although the figure is high, it is less than in other regions of the world, especially if we compare it with the Western Pacific or Southeast Asia.
But it is also important to note that, on the other hand, VHS-2 can increase the risk of contracting and contaging HIV, the virus that causes AIDS.
& ldquo; genital herpes is a great world problem and for the affected person is a very painful disease “, explained WHO sources.
Infected by the VHS-1 virus in the world.
Children under 50:
America:
178 million women (49%)
142 million men (39%)
Europe:
207 million women (69 /%)
355 million men (87%)
Africa:
350 million women (87%)
355 million men (87%)
Oriental Mediterranean:
188 million women (75%)
202 million men (75%)
Southeast Asia:
432 million women (59%)
458 million men (73%)
& ldquo; It can cause important suffering and have serious repercussions on the social and psychological well-being of the patient “.
Prevention
WHO recalls the need for use & ldquo; right and systematic “ of condoms.
In addition, research is being carried out to find more effective preventive methods, & ldquo; such as vaccines or topical microbicides “.
In 2012, new global estimates of the number of infections were published and new cases of neonatal herpes will be announced throughout this year.
& ldquo; We need to accelerate the development of vaccines against herpes virus and if a vaccine is designed that, in addition to preventing HSV-2 also prevents HSV-1, it would have benefits of very broad “ said Sami Gottlieb, doctor of WHO.
Symptoms of melanoma or skin cancer.
Melanomas usually are not painful. The first sign of melanoma is often a change in the size, shape, color, or feeling of an existing lunar.
Melanomas can also appear as a new, black, or abnormal lunar. Symptoms are the result of uncontrollable growth of cancer cells. It is important to remember that most people have polka dots, and almost all polka dots are benign.
In males it usually appears on the trunk or region of the head or neck, while in women it usually appears in arms or legs.
It is necessary to consult the dermatologist when changes are observed in a lunar.
A: Asymmetry: Half of a lunar is not the same as the other half.
B: Irregular edges: unequal edges. Irregular, blurred or jagged.
C: Color: The most dangerous colors are reddish, whitish and bluish on black lesions.
D: Diameter: When the lunar measures more than 6 millimeters or increased in size (greater than 6 mm.) People who are excessively exposed to ultraviolet radiation have a higher risk of Collapse skin cancer.
Prevention
Too much exposure to ultraviolet radiation
The main responsible for melanoma is ultraviolet radiation, fundamentally by inadequate exposure to the sun or other artificial sources, such as ultravioletante tanning lamps. Ultraviolet radiations act on the skin predisposing the appearance of cutaneous tumors.
It has been observed that melanoma appears more frequently in the body areas exposed to the sun and that there is a greater number of latitudes more close to Ecuador. For example, Australia is the country with the highest incidence of melanoma because most of the population has clear skin and latitude conditions a large sun exposure.
People who are excessively exposed to the light of tanning cabinet lamps also have increased risk of skin cancer.
Age
In relation to age, it is more frequent in adults between 30 and 60 years, with an average of 50 years. In children it is rare and if their behavior appears, it is usually relatively benign, without giving metastasis.
Gender
There is no predilection by sex, its incidence is similar in man and women, however, the location is usually different: in young women predominates in lower limbs and older males in trunk, face, neck and shoulders. The distribution of locations can be related to the skin areas exposed to the sun, according to the fashions in the dress.
Personal characteristics that predispose to present this disease
The color of the skin is important to determine the risk of melanoma. For example, the risk of appearance of melanoma is 20 times higher in white people than in the black race. Within the white race the risk varies depending on the phototype.
The phototype of each person depends on the ability to tan, the color of the skin, hair, and eyes. People with the greatest propensity to solar burns, who almost never tan with the sun, have a low phototype and more risk of melanoma.
The four most common types in our latitudes are:
Capacity to tan
Burns
Eye color
Hair color
Skin color
Fototype I
None
always
blue
Redhead
Freckling
Fototype II
Little
sometimes
blue / green
blond
White in winter
Fototype III
good
rarely
brown / gray
chestnut
brunette in winter
Fototype IV
Very good
never
brown / black
black
Racial brunette
It is also more frequent in people who have already had a melanoma, or in people with a history of melanoma in the family. Approximately 10% of all people with melanoma have a history on the family.
Sometimes this may be due to the lifestyle of the family, by frequent exposure to the sun. In other cases it may be due to a genetic mutation.
People with some diseases, as the so-called xeroderma pigmentosum, have a genetic defect that consists of their cells are unable to repair the damage caused by ultraviolet radiation. For them, the risk of ELANOMA at the Early Ages of Life is 2,000 times greater than the general population.
It is also related to precursor injuries, such as people who have multiple polka dots (also called nevus) in adolescence.
People with giant congenital Nevus (big congenital polka dots) have more risk of developing melanoma.
