Brain-eating amoebas kill 10 in Pakistan

A waterborne, brain-destroying species of amoeba has killed 10 people in Karachi, Pakistan, this year, prompting local water officials to increase the amount of chlorine in the city’s water supply and advise residents to use sterilized water when performing a Muslim ritual which involves cleansing the nostrils.

Misbahuddin Farid, managing director of the Karachi Water and Sewerage Board, said the origin of the amoebas had not been determined, according to a report in the Dawn newspaper.

Naegleria fowleri

The amoeba, known by the scientific name Naegleria fowleri, is virtually impossible to detect in the water and its presence in humans is determined by spinal tests, according to information on the water board’s website.

According to the U.S. Centers for Disease Control and Prevention, the Naegleria fowleri amoeba causes a severe brain infection called primary amebic meningoencephalitis. The disease is usually fatal.

The amoeba most commonly enters the body through the nasal passages and usually infects people who have been swimming in warm freshwater lakes and rivers, according to the CDC.

But it can exist in improperly chlorinated swimming pool or heated tap water, the CDC says.

Only one of the 10 victims of the current outbreak in Pakistan had visited a swimming pool, according to another report from the Dawn newspaper, so authorities are focusing on the Muslim ablution ritual, or waddu.

“Special care should be taken when doing waddu, brushing teeth or cleaning the nasal area,” the water board’s website says.

Two people in the U.S. state of Louisiana died from the amoeba last year after apparently contracting it when rinsing their sinuses with a neti pot, a small vessel used to pour warm water into one nostril and out the other.

Three other Americans died last year after contracting the amoeba while swimming.

The Karachi water board said it would increase chlorine content in the water supply for the city of more than 15 million people after tests of more than 900 water samples taken around the city found 22% to be unchlorinated or have insufficient levels of the chemical, according to a report in the Dawn newspaper.

Saghir Ahmed, minister of health for Sindh state, in which Karachi is located, said residents should be safe if they followed the water board’s advice.

“There is no reason to panic and citizens should stay calm and take precautions,” Ahmed was quoted by Dawn as saying.

      so, what is new? Muslims crying foul for any insult in their direction but have no problem killing people and burning other people place of worship over the stupidest things. Oh, that's right! it is done by those extremists. Sure, pal, I call bs on that. Change your religion. It is an intolerant and hateful religion that spreads war and conflict all over the world. Look around you.

    While sympathetic to the water issues in Pakistan, I am more intrigued by the picture of the Kid riding the bicycle with the two large balloons...

    Um, you guys *do* realize that the five Americans who died from this were living in the United States, right?
    Yeah, that's what I said...it's here already.

      Thanks @ banasy
      for reminding us. I now remember those incidents. We have this scourge here to. So much for all those gloating over the deaths 'over there'.

      Ummm...it's not a "scourge". It's not a punishment (from God or Allah or any other deity). It's not even CLOSE to a frequent problem that is persistent and troublesome (except to those poor unfortunates who get it).

      MALARIA is a scourge. N. fowleri is a RARE opportunistic infection.

    Read history.
    since we the Westerners have been making more wars than any other people on this planet and are responsible for killing more of each other and others, you comments seem rather absurd.
    No need to get worked up, man. We have our faults and others have theirs. God, Allah,Ishwar, Yahweh, Budhdha, Jesus and others that millions worship. Need is to understand not be hateful. Got to share this planet, folks.

      good response my freind .... "Let's Share This Planet"

      That is all we ask , and lest help each other, if there are extermists , it does not mean everyone is .. Today, extermism is a religo of its own, and has nothing to do with any God the people want to worship, I will not act as a fool and say there is no terrorism, but it is not in the hands of the innocent muslims, innocent jewish , innocent cristians , we just want to live and eventually die a happy and fullfilled life, having done most of we have wrote on our bucket list, that is all !! " Let us share this planet" that is all that should have been said .. Thank you . Peace love and Unity

      "... Westerners have been making more wars than any other people on this planet and are responsible for killing more of each other and others, you comments seem rather absurd"

      Speaking of absurd, how are your math skills? Care to hazard a guess how many different wars have occurred in Africa and South/Southeast Asia over the past 50 years? Do you count China's cultural revolution in your numbers? Because, last I heard, that 70 million number is more than all wars fought by Western Civilization combined.
