Dengue and Chikungunya: The Dirge of a Nation





The 'buzz' words today throughout the country are 'Dengue' and 'Chikungunya'. Both these flu-like illnesses, brought on by the bite of an infected Aedes aegypti female mosquito, have set the death bells knolling in several Indian states. Dengue is the most common mosquito-borne viral disease in the world according to WHO.

The administrative machinery is battling with a situation that is threatening to go out of hand unless a formidable solution appears on the horizon. The onset of monsoons in the country has led to a surge of breeding among these mosquitoes, which co exists with humans and share the same milieu. Both Dengue and Chikungunya are common to the tropics and are not contagious. Aedes aegypti mosquitoes, which are the causative vectors of both Dengue fever and Chikungunya, carry the virus that causes these diseases. Please note the following about the Aedes mosquito – · It is the female mosquito that feeds on blood as it requires the blood protein to produce its eggs. · The female Aedes mosquito searches for suitable places to lay their eggs and it is usually the stagnant water. The male mosquitoes usually feed only on plant nectar. · Aedes mosquitoes causing dengue usually bite during the day, unlike those that cause malaria, and their biting spree lasts from dawn to dusk. · The mosquito is attracted by the body odours, carbon dioxide and heat emitted from the animal or humans. Dengue, also known as 'break bone fever' is caused by the dengue virus. It sets in eight days after the mosquito bite. Mortality rate can be reduced to 15%, if timely treatment is provided. Dengue fever is sub- typed as Classical and Hemorrhagic.

"More housewives get HIV than sex workers"

With an average of 12 Malaysians testing positive for HIV each day, Malaysia has one of the fastest growing AIDS epidemics in the East Asia and Pacific region. What is more worrying is that the trend is gaining a feminine face, mainly through heterosexual transmission. A new report releases by the Health Ministry and United Nations Children's Fund (UNICEF) yesterday revealed that the trend of new HIV infections amongst women rose drastically to 16% in 2007 from 1.2% of total new cases in 1990.

Surveys showed that in 2006 more housewives tested HIV-positive than sex workers. Besides that, there are thousands of children living in homes shadowed by HIV. The results are a cause for concern as the vulnerability of women and children to HIV are directly linked. Families who are affected by HIV and AIDS, the disease itself does not have so much impact as it can be kept under control for many years with effective treatment. The biggest impact comes from stigma. Mothers whose families are affected by HIV and AIDS are most frightened by the reactions from friends, extended family, colleagues and their communities. Stigma can cause a person to be ostracised by friends and family. It can even cause a HIV-positive husband to disallow his wife to be tested. Besides, stigma can cause a woman to ashamed that she does not seek treatment and meaning an early death and young innocent child left without a mother.

Toxic Chemical Triclosan Found in Common Household Products

A chemical called triclosan poses a health risk, as it is a toxic compound which can promote cancer. The most shocking thing is that triclosan is commonly found in everyday consumer goods such as antibacterial soaps, deodorants, body washes, creams, lotions, cosmetics, cleaning supplies, detergents, dishwashing liquids, and yes, mouthwash and toothpaste.Toothpaste is supposed to help clean your teeth, but what it actually does just might horrify you. When tap water meets toothpaste, the triclosan reacts freely with the chlorine in the tap water to become chloroform (a chlorinated aromatic) and is similar to the dioxins found in the compound Agent Orange. It's a chemical reaction occurring right in your mouth while you brush your teeth. And don't think you are safe once you rinse it all out of your mouth: research shows that it can remain in your mouth after brushing for up to 12 hours, and can be easily absorbed into the tongue and through mucus into the body. (Children are at the greatest risk, as they tend to swallow their toothpaste more while brushing their teeth.)According to the National Coalition Against the Misuse of Pesticides (NCAMP), "Manufacturers of a number of triclosan-containing toothpaste and soap products claim that the active ingredient continues to work for as long as 12 hours after use. Thus, consumers are exposed to triclosan for much longer than the 20 seconds it takes to wash their hands or brush their teeth.""These products produce low levels of chloroform, but that adds up over time. The amount of gas formed is very low but I think the key thing is that we just don't know what the effects are. However, manufacturers do have to list triclosan on their ingredients, so if consumers are worried the best advice is to avoid products with the chemical," said Giles Watson, a toxicology expert.
Triclosan is a Probable Human CarcinogenThe U.S. Food and Drug Administration and the European Union currently regulate triclosan, and the Environmental Protection Agency classifies this substance as a probable human carcinogen.Toothpaste manufacturers claim that triclosan is used because it helps to reduce plaque and kill bacteria, but it actually aids in gum damage and can cause mouth ulcers, say some health experts. These companies like the chemical because it allows them to state the product is a "99.9% bacteria killer" and make claims about the product being a "medicated formula."According to the chemical creator's website, Ciba Specialty Chemicals "invented triclosan more than 35 years ago and in this long time of application without any adverse effects it has proven itself as the 'aspirin' of the antibacterial actives -- helpful without side effects."The popularity of triclosan is a reflection of its unique combination of efficacy against almost all types of bacteria and safety to man and nature which with the currently known substances used cannot be surmounted."The toothpaste manufacturers haven't done any substantial studies that reach a decision on whether to take triclosan out of their products. They continue to say that it is safe and only harmful if ingested. Even then, they say it only affects the nervous system (as if that's something very minor to have harmed).No Good Science Supporting Safety of TriclosanAccording to the American Medical Association: "Despite their recent proliferation in consumer products, the use of antimicrobial agents such as triclosan in consumer products has not been studied extensively. No data exist to support their efficacy when used in such products or any need for them…it may be prudent to avoid the use of antimicrobial agents in consumer products." The chemical company states: "Ciba supports the use of triclosan only if there is a benefit to human beings."So, what if it is shown to offer no benefit to humans? Will they pull it off the shelves now that evidence points to its danger from exposure? (Some toothpaste manufacturers, like Tom's of Maine, specifically state that they do not contain triclosan.)Also Found In Toys, Bedding, Clothing And MoreTriclosan is also used in plastics and fabrics, where it goes under the trade names Microban and Biofresh respectively. It is infused into or used as an additive in a number of consumer products like toys, bedding, trash bags, socks, kitchen utensils, textiles and plastics."Over 95% of the uses of triclosan are in consumer products that are disposed of in residential drains. In a U.S. Geological Survey study of 95 different organic wastewater contaminants in U.S. streams, triclosan was one of the most frequently detected compounds, and in some of the highest concentrations," according to the NCAMP.According to Worldwatch Institute: "In the United States, 75% of liquid soaps and nearly 30% of bar soaps now contain triclosan and other germ-fighting compounds whose prevalence can foster the growth of bacterial resistance."The widespread use of triclosan is now known to create the risk of breeding new, resistant superbugs that may be far more dangerous to human health than the original germs killed by triclosan in the first place. My advice to consumers is to avoid all products containing triclosan.What To Do• Avoid all products that make "antibacterial" claims (unless they are using herbs to accomplish it).• Be aware of the harmful environmental impact of consuming products containing triclosan. The ingredient is not only unhealthy for humans, it's also unhealthy for the environment.• Read the ingredients labels of all consumer products in order to make sure they do not contain triclosan.
