Malaria

Malaria poses one of the biggest risks to people travelling abroad. Malaria is still considered to be the most dangerous disease on the planet, causing more deaths every year than any other infection. More than 1,500 people return to Britain every year with malaria, and despite the best possible treatment, for around 2% of them the disease is fatal.

What is malaria?

Malaria is a serious and sometimes fatal tropical blood-disease caused by a parasite called plasmodium that is transferred by the anopheles mosquito. Malaria is most commonly contracted through a mosquito bite when visiting foreign, tropical countries.

When a person is bitten by a mosquito, the malaria parasite enters the bloodstream and quickly migrates to the liver. There it multiplies, before being released throughout the body.

At this point, the parasite begins invading red blood cells, multiplying within them until they burst- this in turn accelerates the process. This does not take a long time to occur and usually results in the symptoms associated with malaria such as a heavy fever, fatigue, vomiting and diarrhoea.

The malaria parasite depends on both humans and mosquitoes to carry out its deadly cycle of life. Infected mosquito bites a human. Parasite rapidly goes to liver within 30 minutes. The
parasite starts reproducing rapidly in liver. Some parasites lie dormant in the liver and become activated years after initial infections.
Gets into the blood stream, attaches and enters red blood cells. Further reproduction occurs. Infected red blood cells brust, infecting other blood cells. This repeating cycle depletes the body of oxygen and also causes fever. The cycle coincides with malaria's fever and chills. After release, a dormant version of malaria travels through the host's blood stream, waiting to be ingested by another mosquito to carry it to a new host. dormant parasites

Causes of malaria

Malaria was first discovered as a harmful blood parasite in 1880. Caused by the parasite 'plasmodium', a small, single-cell organism, it is spread to humans via the bite of infected mosquitos.

There are over 100 varieties of plasmodium parasites, but only five are identified to commonly infect humans and have various effects on the carrier.

  • falciparum
  • Plasmodium. falciparum - this parasite is located in tropical and suburban areas, predominantly throughout sub-saharan regions of Africa. Around one million people are killed annually as a result of this parasitic strain- and as it can multiply rapidly, most patients are unaware of its deadly potential until it's too late.
  • ovale
  • Plasmodium. ovale - located mainly in West-Africa, Indonesia and the Philippines - this parasite is rarer, yet biologically and morphologically very similar to P. vivax and P. falciparumis. It is reported to cause around 15 million cases of malaria each year.
  • vivax
  • Plasmodium. vivax - located mostly in Latin America, Africa, and Asia,this is the most widespread malaria parasite in the world. Fortunately, it is less deadly than P. falciparum. This strain can cause severe health complications months or years after initial infection, if not treated properly.
  • knowlesi
  • Plasmodium. knowlesi - mainly situated in Southeast Asia, this parasite more commonly infects monkeys but also has the ability to affect humans. Known for its 24-hour cycle, this strain can multiply rapidly once a patient is infected, making it one of the most dangerous.
  • malariae
  • Plasmodium. malariae - this strain is reported worldwide, and is the only malarial parasite to cause three-day symptoms. If left untreated it can develop into a chronic infection, although it is milder than other plasmodium species.

Symptoms of malaria

The first sign of malaria is usually a flu-like fever, and the incubation period (the time of infection until the appearance of symptoms) for each strain generally differs:

  • 9 to 14 days for P. falciparum.
  • 12 to 18 days for P. vivax and P. ovale.
  • 18 to 40 days for P. malariae.
  • 11 to 12 days for P. knowlesi.

During the early stages symptoms that can be experienced are very similar to that of severe influenza.

  • symptomsChills
  • symptomsHeadaches
  • symptomsMuscle aches
  • symptomsFatigue
  • symptomsNausea
  • symptomsDiarrhoea
  • symptomsVomiting

Because of the loss of red blood cells, malaria can also lead to jaundice and anaemia, however the vast majority of sufferers are treated before this stage. Certain cases have also reported back pain and an enlarged spleen.

The plasmodium falciparum, being the most dangerous of the malaria parasites, can potentially cause more severe symptoms; for example, kidney failure, seizures, reduced mental capacity and coma.

Benefits of treating malaria

There are a number of secondary benefits to treating malaria. These include the following:

  • Avoid serious complications

    such as severe anaemia and cerebral malaria.

  • High treatment success rate

    if malaria is treated promptly

  • Associated symptoms can be avoided

    such as fever, nausea, fatigue and influenza-like symptoms

  • Reduced risk of premature birth or miscarriage

    can be successfully avoided if treated promptly

Where is malaria most common

Malaria is most common in hot and humid climates, where the anopheles mosquito lives and thrives. Hotspots in the world where there is a high risk of malaria include:

  • North Africa
  • The Middle East
  • South and Central Asia
  • Sub-Saharan Africa
  • Central and South America
  • The Caribbean
  • Papua New Guinea, the Solomon Islands, and Vanuatu (Oceania)

The fatal plasmodium falciparum malaria parasite is more prevalent in Africa, but is also found in Latin America, Asia and Oceania.

Prevention for malaria

There are a number of basic steps you should take when attempting to prevent malaria.

  • Mosquito repellent creams will help to prevent bites by repelling mosquitoes. The most effective repellents contain DEET (diethyltoluamide)
  • Prescribed medication to prevent malaria
  • Products that contain eucalyptus oil can also be effective
  • There are also certain sunscreens that can prevent against insect bites
  • A mosquito net treated with insecticide is also highly recommended for when you are sleeping, as mosquitoes are most active when it's dark

How to treat Malaria

While taking simple precautions is important, the most successful way to prevent infection is with malaria tablets. There currently isn't a vaccine available to prevent malaria; therefore prescription medication is the best option. Malaria tablets work by preventing the parasites' ability to reproduce, allowing your body to neutralise the infection.

All antimalarial drugs need to be started before you leave for your destination, and also need to be taken for a short period after you return. Malaria can sometimes take 10 - 15 days to cause symptoms after the infection. In rare cases, it can lie dormant for more than a year, although fortunately the most dangerous strain is not known to do this.

Which treatment you need will depend largely on where you are travelling. For lower risk areas such as India, a treatment of Paludrine & Avloclor is recommended. For higher risk areas, either Doxycycline or Malarone can be prescribed. Both of these treatments are considered to be effective against the most dangerous form of the virus.

What are the options we have to offer for Malaria?

Malaria has the potential to be very serious, as it is regarded as the most dangerous disease on the planet, therefore prophylactic treatment is important if you are travelling to an area where malaria is a risk. Beginning a course of medication before travelling can easily prevent malaria. The antimalarials we have available, which are approved by UK qualified doctors, are Doxycycline, Paludrine/Avloclor and Malarone. These Malaria treatments are clinically proven to effectively prevent Malaria and can be ordered quickly and securely online by completing our free, simple online consultation.
