An Unwanted Visitor to the Commonwealth Games

When New Delhi opens its doors to athletes at the Commonwealth Games October 3rd, it would have by then encountered innumerable problems leading to the Games.

While China impressed the world with an almost flawless Olympics, India’s has been dogged with inefficiencies and shoddiness. India’s preparations have been hampered by allegations of corruption, mismanagement and inadequate facilities which threaten whether the facilities will be completed in time at all.

Not least of all, the current impasse on the usage of Blackberry messenger in India will add to communication woes and possible chaos should Indian security agencies impose a ban.

Amidst this, an unwelcome visitor has started to make its presence felt – the dengue virus, the cause of dengue fever. Already, 937 cases have been reported in the last few weeks,  a figure which many consider a gross under-estimate due to a deficient reporting system.(Hospital figures estimate more than 2000 cases in what is described as the worse outbreak in 20 years). Part of the reason for this upsurge is the stagnant pools of water surfacing around the construction sites for the various Games venues.

The Aedes mosquito, which carries the Dengue virus, passes it on when it bites into a human.

The outbreak has already struck two top Indian cyclists and is beginning to instill fear among the arriving Commonwealth Games athletes who fear contracting this disease, especially the most severe form which can cause internal bleeding and death. This fear is heightened because dengue has no known cure or antidote, as are most diseases caused by viruses.

Also, the main fear among athletes is that contracting the disease, however mild, might  impair their chances in the forthcoming Asian Games in November, as well as the Olympics in 2012.

Meanwhile, authorities are scrambling to clear the construction sites of stagnant pools and improving the environment so that India’s aspirations of becoming a successful host remains intact.

Another Battle At Our Doorsteps..Literally

Now that there’s a temporary reprieve  in Gaza, our attention should shift to a series of attacks by various viruses  in the Far East. In China, a potential outbreak (again!) of bird-flu is in the making with the death of a 27 year-old woman in China. Caused by the H5N1 virus, the last outbreak was in Asia in 2003 where  247 died. Find out more about the avian influenza virus( the proper name).

A little-known virus, Chikungunya (pronounced chikoon-goon-nya) has already made its entrance with Malaysia reporting 100 cases per week instead of the usual 100 cases per year. This disease is usually confused with dengue as they have similar presentations, although it follows a more benign course. Read more about it in my recent posting “This Thing called Chikungunya”.


Of immediate concern is the recent outbreak of dengue fever(pronounced den-gie), where the incidence has doubled in recent months in tropical and subtropical areas. In Malaysia, 8 deaths have been reported this month alone. Here’s a good write-up about dengue but I would like to highlight a few pointers:

  1. While the typical symptoms are high fever with chills, rashes, headaches and severe bodyaches in the absence of a runny nose, the latest outbreak has produced unusual symptoms like fits, yellowing of the eyes (jaundice) and kidney failure, all of which require treatment in hospital.
  2. Both Chikungunya and Dengue viruses are carried by the same mosquitoes called Aedes Aegypti. They are the ones with black-and-white stripes on their bodies.  Don’t ask me why, but the females are the culprits and they have adapted themselves so that they don’t fly in your face or make a loud humming sound, preferring to come in low and bite in the ankles. These mosquitoes are attracted to perfume and dark clothing, so party animals, beware!


    Aedes aegypti: only the females bite

  3. Because the Aedes mosquito cannot travel far, it is generally accepted that the breeding ground is within the same compound or area, so one should get rid of pools of stagnant water which can collect in empty bottles, cans and plastic wrapping.
  4. You can confirm whether a fever is due to dengue via blood tests although they are not always accurate. Sometimes it is necessary to repeat the tests several times before they become positive. Nevertheless, diminishing numbers of a component of blood cells called platelets is suggestive of dengue.
  5. There is no treatment that can cure dengue. Like in most viruses, its up to one’s body resistance; and this can be enhanced by rest, adequate fluids and measures to reduce the fever.

At the end of the day, prevention is the mainstay. The way not to get dengue is to eliminate the Aedes mosquito if thats at all possible; failing which, to prevent the insect from biting you and passing you the virus..
