Malaria Lifestyle changes this indicated that malaria affects a lot of people each year and is very dangerous disease which kills nearly a million people. Besides malaria is a harmful disease that has great many people's lifestyle and also affect around the world. People can live their whole life with Malaria if they take the proper medications or treated well.

The environmental factors that influence the malaria life cycle and by that the distribution and incidence of the disease are three main climate Factors these are temperature, precipitation and relative humidity. This indicated that the minimum temperature needed for the mosquito to develop and the minimum temperature for parasite development which could be between 14+°C the optimum temperature for mosquitoes to live and breed in is 20+°C, and the highest temperature that both parasites and the mosquitoes can survive is 40°C.

Skin cancer is the mainly common cancer in women men in their twenties. This indicted sun exposure is the most important lifestyle changes identified to prevent skin cancer. This also indicated that the upholding healthy lifestyles after people have been diagnosed with skin cancer it can be essential to the success of their diagnosis.

Medical issues

With a diagnosis of Skin Cancer it is very important to consider that there is a causal condition causing of Skin Cancer. Because these are many other conditions that may probably cause Skin Cancer. Types of skin more likely to get cancer-sun area may not be available. Although anyone can get skin cancer because it's common and lot of people with light skin tone, but skin cancer can affect anyone this indicated that it doesn't matter whether people consider their skin light, dark, they are still at the risk of getting skin cancer and being in the sun can damage their skin.

Malaria there is no medial issues because there is not completely safe and effective but only treatment of a vaccine. This means that the best possible regimen is an attempt to balance the risk of side effects against the risk of disease. Consequently malaria can be and there is prevention methods get under control.


Skin cancer mostly starts in men and women after the age of 40+. This indicated that the sun's damaging effects begin at an early on age. Although the most common reason of skin cancer is exposure to sun and it have seen that men and women after the age of 40+ spend so much time in outdoor and not aware of the sun.

Malaria mostly effect any life ages especially children, mainly in Africa, which is in all age groups of a population; for malaria. However, in children under the age of 5, the illness tends to be uncommon and more severe. This indicated that Malaria accounts for one in five of all childhood deaths in Africa.

Besides over 40% of the world's children live in malaria-endemic countries and one of million children died for each year. The rapid spread of resistance to anti-malarials drugs, coupled with widespread poverty, weak health communications and the rate at which an illness occurs in a particular area or the population and mortality from malaria in Africa continues to rise.

Environment factors

Malaria is usually odd to a specific location or region, or within a specific group of people in the tropics, with extensions into the subtropics. Current distribution of indigenous malaria.

In the middle of the environmental factors that influence the malaria life cycle and by the distribution and incidence of the disease are three main climate factors: these are



Relative humidity.

Skin cancer is the most relevant environmental factor which causes sun exposure damage to the skin and not repaired can create mutation in the genes. The strength and length of the sun exposure and the age at which the sun exposure occurs and the colour of skin all affects the chances of developing skin cancer. Exposure to environmental factors is influenced by people's behaviour such as activity and spare time activities outdoors and their attitudes also how important they think it is to protect their skin and what steps we are prepared to take to do that.

The causes of my chosen diseases are; Communicable disease: (Malaria) and Non-communicable disease: (Skin cancer)

My rational of chosen skin cancer is because skin cancer is causes by the sun burn and it's the main cause of malignant melanoma and non-melanoma skin cancers. Also my rational of chosen Malaria is because malaria is causes by biting of mosquito.


How many people are affected in the UK and around the world?

Malaria affects many people in the UK and around the world; this is because malaria occur where the mosquito breeds, mainly in country tropical areas. From a UK perspective, it's a threat to people travelling to regions in different countries. For example in Africa, this indicated that Each year lot of people return to the UK with malaria, and about 10 or 20 people a year die as a consequence of the disease.

Skin cancer affects many people in the UK and around the world; this is because skin cancer is one of the most common cancers around the world and UK. This indicated that Each year, more than 20 cases of skin cancer and more than 30 cases of melanoma skin cancer are diagnosed Each year approximately 1 in every 100 people in the UK will develop a new case of skin cancer. It accounts for about the many deaths yearly in the UK.

Geographical distribution


Figure 1.1., the distribution of all deaths among children under five, by cause The World Health Organization and its estimates that approximately million malaria episodes Occurred in 2008 leading to approximately million of people and children deaths each year .

The load of malaria is described in Figures 1.1 and 1.2 in terms of geographical distribution as well as in terms of its relationship to other causes of child mortality.

This pie chart estimates that million cases of malaria occur annually around the world and more than one million victims are killed each year. About 90% of these deaths are from Africa, occurring mostly in children under the age of million deaths occur in around the world. this website states that the World Health Organisation estimates that each year 300-500 million cases of malaria occur worldwide and more than two million people die of malaria. This indicated that each year lot of cases of malaria occur around the world, and over million people die, most of them young children.

Malaria poses a risk to half of the world's population and more than million people die of the disease each year. The malaria map, shows where it is prevalent, has been reduced considerably over the past years, but the disease has defied elimination in areas of intense transmission.

This Map shows that the light colour low intensity and the darker colour shows the highest intensity of malaria transmission (grey no malaria transmission).

This graph shows the difference between 2004 -2009 and how the malaria increases year to year as this shows that 2009 malaria increase more than other years.

The distribution of malaria varies greatly from country to country and within the countries themselves. In all recorded cases outside of Africa were concentrated in nine countries:

Skin cancer

This image shows that the estimated that the lifetime risk of developing skin cancer is 1 in 100 for men and women in the UK and the around the world. This shows that many women and money die for skin cancer over the years.

Therefore skin cancer can occur anywhere on the body and is more dangerous. It's related to the common mole and changes in the appearance of moles on people's body should be checked by their GP.

Figure 1.1 depicts the percentage distribution of malignant melanoma on parts of the body (percentages may not add due to rounding).Figure 1.1: Percentage distribution of malignant melanoma on parts of the body

Skin cancer is more common in women than men with an M: F ratio of 4:5. In 2007 it was the sixth most common cancer in females and the ninth in males: for both sexes combined it was the sixth most common cancer. The distribution of cases on the body also varies by sex (see table 1.1) over a third of male cases arise on the trunk of the body, particularly the back, while the most common site for females is on the legs.

By age and sex - The latest statistics show that 5,697 cases of skin cancer were diagnosed in women and 4,975 in men in the UK in 2007. 7-10 the numbers and rates for the constituent countries of the UK are shown in Table 1.1. 3Numbers and rates of new cases for malignant melanoma in the UK
