Malaria is a disease of poverty; it is a disease of the developing, underdeveloped and developing worlds. Although cases of the disease are sometimes noted in the US and EU, these are mostly transferred from tropical countries.

The reason is tragic: although people in the poorer countries know as much as anyone else about malaria, and of how it could be prevented, they do not have the wherewithal to prevent malaria due to lack of money and healthy living facilities. Malaria is a disease of the swamps; of mosquito bites, of sleeping in the open air and working in marshy fields. These things, swamps, dirty water, sleeping outside and mosquitos are the lot of poor people in undeveloped countries. They do not have the money to clean swamps, carry on expensive pest control measures or build a proper, pest free house to live in. They have to work in fields, in swampy conditions, and by a quirk of nature, most of the poorer people of the world happen to live in the tropics, where heavy rainfall, humid and hot weather and swamps abound, all breeding grounds of mosquitos. This is the basic reason why malaria is such a prevalent cause of death in poor countries, especially in sub-saharan Africa where treatment and prevention facilities are next to nil.

Over 250 million people suffer from malaria every year, of which about one in twenty five die. Of these large numbers, almost 80 to 90 percent are from sub-saharan Africa alone. The rest of the deaths are evenly distributed among countries of central America and Asia. Malaria is also a disease of rural areas; studies have shown that the majority of cases of malaria occur in villages – where, of course, there are more malaria carrier mosquitos.

Malaria is both a preventable and a curable disease; quinine, an extract of the cinchona plant, is a complete cure for malaria. It is tragic that poverty lets people neither prevent this disease, nor cure it with the life saving but expensive quinine.

It will be common for the globe trotter to eventually traipse through an area prone to Malaria at some point in time. Travel throughout tropical and sub-tropical areas and even some parts of Eastern Europe you could be potentially exposed to the malaria parasite.

Malaria is a parasite transmitted in the majority of instances via a specific species of mosquito. If an infected mosquito bites an individual they can become infected with the parasite which instantly travels via the bloodstream to the liver and back into the bloodstream.

Individuals who contract malaria usually experience flu-like symptoms including but not limited to high fever, chills, vomiting, jaundice, diarrhea, abdominal pain, and headache. Left untreated Malaria is capable of causing dangerous issues and even death. Children, pregnant women and individuals who live in areas where malaria is uncommon are at a greater risk for dying if they contract the disease during travel.

As malaria parasites evolve they are becoming more and more resistant to some of the antimalarial medications on the market.

Travelers are urged to protect themselves in a variety of ways: taking the antimalarial medications which have the greatest chance of providing the highest level of protection for the specific area in which they will be traveling to.

In addition to medicine, there are also non medicinal prevention methods.

All individuals should avoid contact with mosquitoes while visiting areas prone to malaria. People are instructed to utilize effective insect repellent containing DEET to avoid the bite of the mosquito. When outside between the hours of dusk and dawn (the dawn of the mosquitoes day) individuals should cover their arms and legs with light colored clothes in an attempt to reduce the risk of being bitten.

A bed net, which is a net covered in insecticides should be used while sleeping to repel mosquitoes on the blood hunt at night.

What are the symptoms of Malaria?

An individual contracts malaria when they are bitten by a mosquito carrying the plasmodium parasite. When an individual is bitten plasmodium enters the blood stream. The result of this bite could potentially be symptoms that range from moderate to severe, and sometimes ends in death. Malaria causes 1.5 to 2.7 million deaths each year.

Symptoms of Malaria

When an individual contracts Malaria they will experience attacks of symptoms in intervals ranging every 48 to 72 hours. There are typically three stages to a malarial attack an individual first experiences the cold stage, then they enter into the hot feverish stage, and then finally ease into the profuse sweating stage.

During the cold stage an individual will be incredibly cool, as a result the individual might shiver, and get a severe headache and an incredibly cold feeling body temperature.

In the hot phase an individual will eel incredibly hot and desire to shed any and all clothing or covering. This is occurring due to an intensely high fever (often times getting up to 105 degrees Fahrenheit.) This is incredibly dangerous, especially in children.

After both of those pass an individual will begin to sweat. When an individual’s fever sets heavy sweating begins. The sweating can become incredibly serious soaking the bed and the area around an individual. During this time the subject will feel weak and desire increased amounts of sleep.

These are all symptoms of malaria as they progress in stages. An individual who has been infected by malaria in the past is nearly immune to contracting the disease. So a mosquito bite is not as terrifying or risky. However this is not true of an individual who is not immune to malaria. An individual with no immunity will easily fall victim to the disease if bitten or infected via blood transfusion, needle sharing, or organ donation.

Simple Methods Of Preventing Malaria

Malaria is a common disease in the tropical countries. Though it is prevalent in many countries all over the world, it is seen commonly in the developing nations and also in the tropical countries. The reason for the high prevalence in these countries is because of the fact that the mosquitoes thrive in the climate. The other reason for the common occurrence of malaria in these places is also because of the low socio economic condition of the people that causes overcrowding, poor hygienic conditions. All of these play a role in the cause and the transmission of the disease.

There are certain methods that can be used to make sure that the disease is prevented. These measures are so simple that the prevention of Malaria is the best method of making sure that it is not occurring. There are four different methods that can be commonly used in the prevention of the disease and they are listed here.

Any person who is traveling in a place where the risk of being infected with the malaria parasite should wear protective clothing. There is no specific clothing that will protect the person, but any dress that causes the exposed areas to be covered to prevent the bite of a mosquito will prevent the disease.

The use of mosquito repellents will also make sure that there are no mosquitoes biting the person. There are many repellants that are very effective these days. This will help the person to be able to overcome the cause of the disease completely.

Mosquito nets have been very effectively used to prevent the disease as it is the sleeping time when the person is infected with the malaria parasite commonly. Making sure that the mosquitoes cannot enter the house by taking preventive action like netting the house is another method that can help prevent malaria.

Malaria is a disease that is caused by mosquitoes. If the mosquitoes are controlled, then Malaria can also be overcome. There are many people who try a lot of things to try and prevent the disease. They might use various protective methods like netting the windows in the house and other methods. This may help to prevent the mosquitoes that enter the house. If the same person goes outdoor, then the risk of the mosquitoes biting the person increases and this can lead to various instances of mosquito bites.

The best method that can be used to prevent the mosquito bites is to reduce the number of mosquitoes that are present. Though this is not a fool proof method as the mosquitoes may not die, they can be reduced in number. This is also the reason for the hygiene in a particular geographic area to be very good. Increased hygiene means that there will not be water stagnation. Drainage will improve and this can prevent the mosquitoes from breeding.

In many places, there may still be stagnation of water. In these water bodies, the introduction of gambusia fish will help to keep the mosquitoes under control because they feed on the mosquito larvae. If there is any water body present in a particular area, then the risk of Malaria will increase. So the single most important method that can help to prevent the breeding of mosquitoes is to make sure that the water bodies are covered to prevent the mosquitoes from settling in the water to lay the eggs. The life cycle of the mosquito can also be curtailed by the use of various medications that kill the larvae in the water. Though various methods of killing the mosquitoes and larvae are present, the improvement in hygiene that increases water drainage and hygiene remain the best method to overcome Malaria.

Why Can Malaria Be Prevented Very Easily

Malaria as a disease is a very common one. It affects millions of people from all over the world each year. The death and the damage that the disease causes in the human population is immense. There are many people who suffer repeatedly from the disease because they are bitten by these mosquitoes repeatedly. Though the disease spreads on a massive scale and affects millions all over the world, the treatment is very simple, unless the person suffers from the most severe form of Malaria.

The prevention of the disease is much simpler, but the people have to know about the disease to be able to take care of themselves. The best method that can help the person to prevent the disease is to prevent the mosquito bite. This is more simple when it is said that when it is done. This is because the mosquitoes seem to find some way of biting their quarry.

In spite of this, it is much easier to prevent Malaria than it is to prevent various other diseases. The primary method that can be used to prevent the Malaria is to use mosquito nets. These nets are very useful to keep the mosquitoes away when the person is sleeping. Other than the time of sleeping, the person who needs to protect from getting Malaria should make sure that they use a lot of mosquito repellents. The covering of the exposed parts of the body when the person is going outdoor is very important. If any parts of the body are exposed, then it too can lead to the incidence of Malaria. So, it should be remembered by every person in areas that are endemic to Malaria that it is very easy to prevent Malaria by taking certain simple precautions like using mosquito nets and mosquito repellents.

Mosquito Nets In The Prevention Of Malaria

Malaria is a common disease in the tropical countries. This does not mean that the disease Malaria is not present in the developed countries. There are incidences of Malaria reported from almost all countries in the world. Malaria is transmitted from one person to another because of the bite of a mosquito. When the mosquito bites a person who is infected with Malaria and then bites another person who is not infected, the infection is transmitted from the affected person to the healthy person.

The best method of preventing the occurrence of Malaria is by the use of various repellents for Malaria. The repellents have various uses, but they have certain disadvantages too. The repellents that are used to keep the mosquitoes away are all effective only for a particular period of time. Once the effect of the mosquito repellent wears off, it can cause the mosquitoes to bite and cause the disease.

The best methods of keeping away the mosquitoes are the nets that are used when you sleep. If you live in a area where there is a lot of mosquitoes, then the best thing that can be done is to use these nets at night when you sleep. During the day time and other times, repellents are useful and when a person is active, there is a less risk of mosquito bites. Most of the malaria causing bites by the mosquitoes occurs during the night when the person is sleeping. This can be prevented by the regular use of the mosquito nets.

The nets to prevent the entry of mosquitoes are either normal nets or they can have a layer of mosquito repelling medication on it. This will prevent the mosquitoes from going near the net and prevent Malaria in the person. This is the economical and efficient method of avoiding Malaria.

Reason For Difficulties In Preventing Malaria

Malaria is a common disease that can lead to complications including death. The person who is affected by the disease should make sure that it does not occur again. Immediate treatment is also needed. There are various measures and methods that have been used by the various governments and health agencies in the aim of preventing Malaria. Most of these methods have fallen by the wayside because of certain logistical and other practical difficulties.

The main reason for many of the preventive measures failing is because of the sheer number of the mosquitoes that are present. There are so many of them all over the world that to make them stop biting a person is very difficult.

The climate conditions can lead to various changes in the number of mosquitoes. In rainy season, there is a sudden increase in the number of mosquitoes. This is also the time when the mosquitoes breed a lot. They bite so many people that people are commonly affected by Malaria in this season. Water stagnation will also increase in the rainy season casing the mosquitoes to breed very easily and effectively.

Travel by people is also another important reason for the number of people being affected by Malaria. The people cannot be prevented from traveling. To overcome this problem, the people should make sure that they take precautions while traveling. This is the only method that can be used. Most instances, the malaria spreads to a new area because of the traveling population.

Inaccessible places are the common areas where Malaria is common. Urban areas see very few cases of Malaria, but the numbers of people who are affected by Malaria in the rural areas are more common. The healthcare in rural areas is poor and ignorance in these areas also causes more instances of Malaria in these areas. All these reasons are the practical problems in preventing Malaria.

Preventing Malaria

Malaria is a serious illness. Like many other illnesses and sicknesses, it’s transmitted by mosquitoes. This is a big problem in countries where there are many mosquitoes and where there aren’t very many good ways of dealing with them. Even though mosquitoes are small, they can certainly cause major difficulties for people who aren’t prepared to kill them. It’s a good idea to keep mosquitoes from biting you, even if you don’t live in an area where malaria is a problem. Mosquito netting can help to protect you at night, but during the day you’ll want to have some type of repellent.

Most experts recommend using something with deet in it, but there are people who are very sensitive to that chemical. For those people, deet won’t work. There are, however, other options that they can use so they can still keep mosquitoes from landing on their skin and biting them. Be sure to use your repellent on your clothing, too, because mosquitoes can and do bite through things like socks and shirts. They can be very aggressive when they’re hungry, and there are often swarms of them in places where there is a lot of standing water and high humidity.

Keep standing water to a minimum around your house as much as possible. After it rains, make sure you dump out any bowls, flower pots, or other containers that can hold water. If you don’t leave water standing around, it’s not possible for mosquitoes to breed. Of course, that doesn’t mean your neighbor won’t have standing water, so you still have to protect yourself with repellent even if you keep water from standing around your house. If you are bit by a mosquito, the odds are low that you will get sick. If you do notice symptoms, though, see your doctor so you can be tested and treated.

How Malaria is Transmitted

There is only one known species of mosquito that is able to transmit malaria: the female Anopheles. In lesser instances, malaria can also be transmitted through contact with infected blood. Luckily, the disease cannot be passed between humans through casual contact or even airborne pathogens such as the spreading of influenza or the common cold.

The female Anopheles mosquito becomes infected with the parasite through a prior blood meal from an already contaminated human or animal. When the mosquito first bites an infected individual, a small amount of blood is taken. Within this small sample is a parasite which proceeds to grow in the mosquitos gut for over a week and travel to the salivary glands. The next time that mosquito takes blood, the parasite-saliva mix are injected into the human with the bite completing the transmission of the disease.

Once the parasite is in the blood, it immediately travels to the liver where it grows and quickly multiplies. After an incubation period, the parasites leave and enter the red blood cells which carry oxygen. At this point the parasite continues to grow, multiply and mature. The organism then ruptures each blood cell and attacks another. The toxins released from the rupture are what causes the symptoms associated with malaria.

Another less common method of infection is through contact with contaminated blood. This can occur during blood transfusions, sharing of needles or syringes and an organ transplant. Additionally, a mother can pass the disease to her fetus if pregnant when infected with malaria. This is known as congenital malaria.

Transmission is quick, simple and usually goes unnoticed when bitten by a mosquito. There are plenty of preventative measures that can be taken when visiting a high-risk country. Some of the most effective methods include, preventative health medicine, insect repellent, bed netting, gauze around entrances and a fully-functional air conditioner.
