What is Anti Malaria?

Malaria is a serious tropical disease spread by mosquitoes. If it isn't diagnosed and treated promptly, it can be fatal.

A single mosquito bite is all it takes for someone to become infected.

Symptoms of malaria

It's important to be aware of the symptoms of malaria if you're travelling to areas where there's a high risk of the disease. Symptoms include:

• a high temperature (fever)
• sweats and chills
• headaches
• vomiting
• muscle pains
• diarrhoea

Symptoms usually appear between 7 and 18 days after becoming infected, but in some cases the symptoms may not appear for up to a year, or occasionally even longer.

When to seek medical attention

Seek medical help immediately if you develop symptoms of malaria during or after a visit to an area where the disease is found.

You should still seek medical help even if it's several weeks, months or a year after you return from travelling.

If there's a possibility you have malaria, a blood test will be carried out to confirm whether or not you're infected.

You should receive the results of your blood test on the same day. If you have malaria, treatment will be started straight away.

What causes malaria?

Malaria is caused by a type of parasite known as Plasmodium. There are many different types of Plasmodia parasites, but only five cause malaria in humans.

The Plasmodium parasite is mainly spread by female Anopheles mosquitoes, which mainly bite at dusk and at night. When an infected mosquito bites a human, it passes the parasites into the bloodstream.

Malaria can also be spread through blood transfusions and the sharing of needles, but this is very rare.

Malaria risk areas

Malaria is found in more than 100 countries, mainly in tropical regions of the world, including:

• large areas of Africa and Asia
• Central and South America
• Haiti and the Dominican Republic
• parts of the Middle East
• some Pacific islands

The 2014 World Malaria Report, published by the World Health Organization (WHO), estimates there were 198 million cases of malaria worldwide and 584,000 deaths in 2013.

Malaria is not found in the UK, although about 1,586 travellers were diagnosed with the disease after returning to the UK in 2014, and three people died.

The Fit for Travel website has more information about the risk of malaria in specific countries.

Preventing malaria

Many cases of malaria can be avoided. An easy way to remember is the ABCD approach to prevention:

• Awareness of risk – find out whether you're at risk of getting malaria before travelling
• Bite prevention – avoid mosquito bites by using insect repellent, covering your arms and legs, and using an insecticide-treated mosquito net
• Check whether you need to take malaria prevention tablets – if you do, make sure you take the right antimalarial tablets at the right dose, and finish the course
• Diagnosis – seek immediate medical advice if you develop malaria symptoms, as long as up to a year after you return from travelling

Speak to your GP if you're planning to visit an area where there's a malaria risk. It may be recommended that you take antimalarial tablets to prevent infection.

Treating malaria

If malaria is diagnosed and treated promptly, virtually everyone will make a full recovery. Treatment should be started as soon as the diagnosis has been confirmed.

Antimalarial medication is used to both treat and prevent malaria. Which type of medication is used and the length of treatment will depend on:

• the type of malaria
• the severity of your symptoms
• where you caught malaria
• whether you took an antimalarial to prevent malaria 
• whether you're pregnant

In some cases, you may be prescribed emergency standby treatment for malaria before you travel. This is usually if there's a risk of you becoming infected with malaria while travelling in a remote area with little or no access to medical care.

Complications of malaria

Malaria is a serious illness that can get worse very quickly. It can be fatal if not treated promptly.

It can also cause serious complications, including:

• severe anaemia – where red blood cells are unable to carry enough oxygen around the body, leading to drowsiness and weakness
• cerebral malaria – in rare cases, the small blood vessels leading to the brain can become blocked, causing seizures, brain damage and coma

The effects of malaria are usually more severe in pregnant women, babies, young children and the elderly. Pregnant women in particular are usually advised not to travel to malaria risk areas.
