Natural Hazards
A physical event, such as a volcanic eruption, that does not affect human beings is a natural event but not a natural hazard. A natural phenomenon that occurs in a populated area is a hazardous event. A hazardous event that causes large numbers of fatalities and/or overwhelming property damage is a natural disaster. In areas where there are no human interests, natural event do not constitute hazards and they rarely result in disasters.
Climate change is one reason malaria is on the rise in some parts of the world, new research finds, but other factors such as migration and land-use changes are likely also at play. The research on why malaria has been spreading into highland areas of East Africa, Indonesia, Afghanistan and elsewhere.
common in warm climates of Africa, South America and South Asia. The development and survival, both of the mosquito and the malaria parasite are highly sensitive to daily and seasonal temperature patterns and the disease has traditionally been rare in the cooler highland areas.
The spread of malaria in highlands is of great concern to those who work to contain the disease. But understanding the many factors that influence the spread of highland malaria could help with efforts to control the disease worldwide.researchers,Chaves and KoenraadtIn particular the study highlighted the sensitivity of upland areas, where a change of just 2°Celsius could put previously malaria-free regions at risk of epidemics.
"This is one of the first studies to use such a high-resolution climate model across such a wide swathe of Africa," says Dr. Andrew Morse from the University of Liverpool, one of the authors of the research, published in Environmental Health Perspectives.
Malaria flourishes in warm, humid environments, so surface temperature and rainfall are the two most important natural factors that influence where it will strike and how quickly it's likely to spread.
According to new research, the disease's ability to spread depends not just on how temperature changes from month to month and year to year, but also on how temperature fluctuates throughout the day.By looking at climate patterns in more detail, the new data suggest that scientists may need to reconsider their predictions of here malaria epidemics could strike next.
the disease is also spreading through water supply by which kids are consuming and getting infected this has cause the children to have the unforgettably feeling of diarrhea, its killing them slowly and this cause has not yet to be being over looked by the government in Africa.... the climate in most of south and north africa are a major cause of why the malaria disease is spreading the water that accumulates in the rivers and sometimes over floods the area attract the mosquito in which malaria is already being spread and the consuming of the water is a second way on how the disease is ending up in the childrens body and affecting their health.
According to the World Bank, as many as two billion people lack adequate sanitation facilities to protect them from water-borne disease, while a billion lack access to clean water altogether.
Malaria is an acute febrile illness. In a non-immune individual, symptoms appear seven days or more (usually 10–15 days) after the infective mosquito bite. The first symptoms – fever, headache, chills and vomiting – may be mild and difficult to recognize as malaria. If not treated within 24 hours, P. falciparum malaria can progress to severe illness often leading to death. Children with severe malaria frequently develop one or more of the following symptoms: severe anaemia, respiratory distress in relation to metabolic acidosis, or cerebral malaria. In adults, multi-organ involvement is also frequent. In malaria endemic areas, persons may develop partial immunity, allowing asymptomatic infections to occur.
six natural disaster events thought to be exacerbated by climate change. Those events include ozone air pollution, heat waves, the spread of infectious disease, river flooding, hurricanes, and wildfires. in which malaria is just one of the thousands of diseases spread by climate change and in how it affects a lot of places in in the world in by which 1.3 billion people dont have access to clean water to drink and another 2.5 billion don't have access to clean water for there proper sanitation or daily uses.

- Malaria is a life-threatening disease caused by parasites that are transmitted to people through the bites of infected mosquitoes.
- In 2010, malaria caused an estimated 655 000 deaths (with an uncertainty range of 537 000 to 907 000), mostly among African children.
- Malaria is preventable and curable.
- Increased malaria prevention and control measures are dramatically reducing the malaria burden in many places.
- Non-immune travellers from malaria-free areas are very vulnerable to the disease when they get infected.
