Malaria And Dengue Fever.

Malaria

Malaria is a potentially fatal disease that is spread exclusively through the bite of the female Anopheles mosquito. It is caused by a parasite called Plasmodium, which multiply in the liver and then affect red blood cells.

There are essentially four types of plasmodium parasites.

  • Plasmodium Falciparum,
  • Plasmodium Vivax,
  • Plasmodium Malariae,
  • Plasmodium Ovale.

Malaria is prevalent throughout tropical and sub tropical regions, and outbreaks of various intensities and length are common in many countries throughout these regions, so the ‘danger zones’ can often wax and wane.

Symptoms of Malaria include sever flu like symptoms such as shivering, coldness, a dull muscular ache, mild to severe fever, rash, headaches, diarrhoea and vomiting. They can occur anytime, most often up to fifteen days after the actual bite but can in some people take up to 4 weeks.

The big danger of these initial symptoms is that they can be very difficult to actually recognise as Malaria, and if not treated promptly it does have the potential to cause serious long term damage to the liver or even be fatal. Diagnosis can only be made by health professionals taking a blood sample so it is important that you get yourself to adequate medical facilities as soon as possible if you suspect you have contracted Malaria.

What to do?

There are basically only two ways you can combat Malaria, by mosquito avoidance measures and anti malarial prophylaxis.

It is important that you check up to date information with your travel clinic, the World Health Organisation or the CDC before you travel, and get up to date and accurate information specific to the region you are travelling to, as different medications will be effective, or non effective, in different regions, and will also be prescribed based on your own specific medical history. Not all anti malarial medication suits everyone, and which one you decide to take should be discussed with the practice nurse or physician in specialist clinics.

If you do contract Malaria, then hospitalisation is necessary. The only treatment is the same prophylaxis used to prevent Malaria, but if you have taken preventative prophylaxis and contracted Malaria anyway (they are not 100% effective), then a different one, or even a combination, will be used to treat you. If medical help is sought quickly enough then full recovery is possible.

Dengue Fever

Dengue fever is a viral infection transmitted by the bite of an infected Aedes aegypti or more rarely the Aedes albopictus mosquito. Any mosquito that bites during the daylight hours has a chance of carrying the disease. It is becoming increasingly problematic throughout the tropical and sub tropical world from South America to Asia, and has become a major international public health concern. Serious intermittent outbreaks occur frequently right across South and Central America, Africa and Asia.

Symptoms can include flu like symptoms similar to the symptoms of Malaria, a mild to severe fever, rash, muscle, joint and bone pain, which can be extremely painful and has led to the nickname break bone fever.

There is no vaccine or cure for dengue fever and there is no treatment, but it is not fatal and will usually resolve itself. Dengue hemorrhagic fever (DHF) however is a more severe form of dengue and can sometimes be fatal if not recognised and medically managed by physicians and nurses quickly enough.

What to do?

You should always check for recent outbreaks in areas you want to travel to and plan accordingly. There is no treatment or medication for dengue, the only thing that can be done if you contract it is to treat the symptoms. Stay well hydrated, rest and take analgesics for the pain. The best form of defence against dengue is mosquito avoidance. It is almost impossible to completely protect yourself, but by taking specific avoidance steps you can significantly reduce the risks.
