Dengue (pronounced den-gee) fever affects between 50-100 million people each year, with around 25,000 people dying from the disease. It’s most common in south America and parts of Africa, and is also known as breakbone fever because it causes such intense pain in the bones. Dengue fever is a virus that’s spread by mosquitoes, and there is no vaccine or effective drug treatment to prevent or cure it.

Adventure in Uganda

On my second day in Uganda, we went white water rafting on the Nile, near a town called Jinja. The rapids are just Screenshot 2013-10-14 at 10.50.13down river from Lake Victoria, which is where the Nile starts.

The rapids are caused by the force of the water as it crashes over rocks and around islands in the river. There used to be more rapids there, and the famous Bujugali Falls. However, a couple of years ago a dam was built across the river, which has made part of it more like a lake and has increased the water levels, wiping out lots of the rapids, including Bujugali. However, below the dam, the rapids are still just as scary! The rapids are a favourite for rafters and kayakers all over the world.

Can you imagine not being able to turn on a water tap? Can you imagine not even having a water tap?
Today’s challenge is to notice when you do something that we all take for granted – turning that tap and letting the water flow.
Washing your hands, cleaning your teeth, taking a shower. You are thirsty, so take a big gulp of water straight from that tap after playing outside in the sun.
Every time you turn on a tap of water, think about how easy it was and what you would do without running water.

What do you think of when you hear the word AFRICA?

Do you think of safaris? And villages?

 

You might think of drums and dancing. Or do you think of something else?

These are stereotypes of Africa, which means they are a conventional, over-simplified image or impression of the country.
