Malaria is a serious disease caused by a parasite transmitted via mosquito bites that kills over 1 million people in Africa each year, most of them children. The parasites multiply in the liver and infect red blood cells, causing symptoms like fever and vomiting. It hits poor communities hardest by making people too sick to work and potentially face deeper poverty. Prompt treatment and preventative measures like insecticide-treated bed nets can significantly reduce malaria cases and deaths, especially in children, with donations helping to deliver and distribute vital interventions.

1. Mosquitoes transmit a variety of deadly diseases like dengue, malaria, chikungunya, and Zika virus. The document discusses the symptoms and transmission of these diseases.
2. Only female mosquitoes bite humans to obtain blood meals that are necessary for egg development. They are attracted to heat, carbon dioxide, and scents from sweat.
3. Mosquitoes can sense humans from up to 30 feet away using heat sensors. They breed in small, stagnant bodies of water and transmit diseases globally.Malaria

The document discusses malaria, including that it is an infection caused by a parasite transmitted through mosquito bites, most commonly in Africa due to its hot and humid climate. It kills approximately 2 million people per year, most of them African, though 300-500 million people are infected annually. While preventable and treatable, there is currently no commercial vaccine for malaria.The Pesty Mosquito

Mosquitoes have been around for over 30 million years and come in more than 3,500 species. They are small flies in the Culicidae family that feed on nectar and plant juices, but female mosquitoes require blood meals from humans and animals to develop their eggs. Mosquito-borne diseases infect millions of people annually. The adult female mosquito lays eggs in standing water, which hatch into larvae and develop through pupa and adult stages. Mosquitoes are attracted to humans by the carbon dioxide, lactic acid, heat and contrasting colors we emit and can transmit viruses and parasites that cause deadly illnesses like malaria and dengue fever.A treatement for mosquitoes

Mosquitoes go through four life stages: egg, larva, pupa, and adult. Eggs are laid on water or damp soil and hatch within 48 hours. Larvae live in water and molt four times before transforming into the pupal stage. In the pupal stage, which lasts about two days, the mosquito transforms into an adult. As an adult, mosquitoes can transmit deadly diseases like malaria, dengue, chikungunya, and filariasis to humans through bites. Malaria is caused by a parasite transmitted by the Anopheles mosquito, while dengue and chikungunya are transmitted by the Aedes mosquito.Malria ppt

Malaria is transmitted through the bites of infected Anopheles mosquitos. The malaria parasites travel to the liver and later multiply in red blood cells, causing symptoms like headache, fever, and potentially coma. Preventative measures include protective bed nets treated with insecticide, which can significantly reduce transmission when coverage is high.

Malaria is a major public health concern in Malawi, especially among pregnant women and children under 5. It is the leading cause of morbidity and mortality in the country, accounting for one-third of outpatient visits. The government and organizations like USAID and PMI are working to reduce the burden of malaria through initiatives like indoor residual spraying, distribution of long-lasting insecticide treated bed nets, and improved access to artemisinin-based combination therapy. These efforts have led to a 44% reduction in anemia rates among children in some areas. However, more funding is still needed to fully address the issue of malaria in one of the poorest countries in the world.Why insects are called pests

Many people think that rabies is transmitted through only dog. But its not true, rabies is transmitted through not only dog, but also spread through bite or scratch from rabies infected animal like dog, bats, raccons, fox, monkeys etc.. Any open wound exposed saliva of infected animal can be potential source of infection.
Many European countries and North America have already eliminated rabies as a public health problem through mandatory vaccination of dog and good access to post exposure prophylaxis for human beings.
More than 95% of human death occurs in Asia/ Africa. And 99% of human rabies cases came from dogs. There is a small proportion of human rabies reported due to transmission via wild life (such as fox, wolves, jackels, raccoon, bats). Rabies kills more than 60,000 people each year (that is one death in every 9 minute) over 150 countries.Football World Cup 2014 Health Advisory from Riskpro

Fasciola hepatica, or the liver fluke, is a parasitic flatworm that infects livestock like cattle and sheep and causes significant economic losses. It has a complex lifecycle involving an intermediate snail host and affects animals by causing anemia, weight loss, and liver damage. Diagnosis involves examining feces for eggs of the parasite. Treatment of infected animals includes dewormers like albendazole or triclabendazole. Preventing exposure by controlling snail populations and removing animals from flooded pastures can also limit the spread of this parasitic infection.

Insects are beautiful creature in nature and found in every environment on Earth. Many insects are considered to be pests by humans. However, some insects are crucial components of many ecosystems, performing many important functions such as pollination, decomposition and some insects produce useful substances, such as honey, wax, lac, silk, some insects act as food and medicine but some insects like mosquitoes, especially female ones act as vector for many bacterial and viral diseases because female mosquitoes needs nutrition contained in blood to help develop their eggs. Viruses take advantage of this biological requirement of mosquitoes to move from host to host. The mosquitoes spread pathogens by sucking our blood cause over half a million deaths each year and hundreds of millions of cases of severe illness.

2) It contains 75% of the Earth's fresh water.
3) It reflects heat from the sun, helping to reduce global warming.
There are arguments both for and against developing Antarctica. Those for development say its resources could help address issues like rising oil prices and food shortages. Those against say Antarctica should be preserved as the world's last untouched wilderness and developing it could harm wildlife and the environment. The future of Antarctica is debated between prioritizing protection versus sustainable use of its resources.More Related Content

Deserts1 Why Are Deserts Hotsarah marks
油
Deserts are areas that receive less than 100mm of rainfall per year. Hot deserts are found between 30 degrees north and south of the equator, where there is little cloud cover and the sun's rays directly heat the land. Deserts are dry because of high pressure systems that form at 30 degrees latitude, which prevent cloud formation and rainfall. The lack of clouds also means heat easily escapes at night, leading to large temperature fluctuations.Sahelcasestudy

Desertification is the process by which fertile land becomes desert. It is affecting parts of Africa, especially the Sahel region. The main causes are human activities like overfarming, overgrazing, and deforestation combined with low rainfall. This degrades the soil so plants cannot grow, leaving the ground unprotected from further erosion by wind and water. As the land becomes desert, it negatively impacts people, wildlife and the economy through famine and forced migration. Efforts to stop desertification include planting trees, terracing land, and building irrigation systems.Similar to M A L A R I A Y E A R9 (14)

This document discusses various filarial worms that infect humans. It notes that approximately 250 million people worldwide are infected with filarial worms, which are spread by mosquitoes. Different species of filarial worms inhabit different locations in the body, such as the lymphatic system, subcutaneously, or abdominal cavity. In some cases of persistent infection of filarial worms in the lymphatic system, elephantiasis can develop due to blockage and inflammation of lymphatic ducts. River blindness is also discussed, which is caused by filarial worms transmitted by blackflies, infecting up to 30 million people worldwide and blinding over 300,000.Africa diseases.ppt

Malaria is an infectious disease spread by mosquitoes that infects over 3 billion people worldwide. It is caused by a parasite called Plasmodium, which has a complex life cycle involving both human and mosquito hosts. Young children and pregnant women are most vulnerable. While rates of malaria have decreased, it remains a major public health problem and cause of economic hardship in developing countries. Controlling mosquitoes and proper diagnosis/treatment of infections are key to reducing the malaria burden.PROJECT ON MALARIA.pdf

Malaria is caused by a parasite transmitted through mosquito bites. It affects over 3 billion people worldwide and causes hundreds of thousands of deaths each year, mainly in sub-Saharan Africa and among young children and pregnant women. The malaria parasite has a complex life cycle involving stages in both the human and mosquito hosts. Prevention methods target different stages of the life cycle, including insecticide-treated bed nets, indoor residual spraying, antimalarial drugs, and mosquito control. While progress has been made in reducing malaria cases and deaths, it remains a major global health problem, especially in poor tropical and subtropical regions.Essay On Malaria

Malaria is spread by the bite of infected female Anopheles mosquitoes. It occurs most commonly in tropical and subtropical regions of the world. The spread of malaria depends on factors like rainfall, mosquito types in an area, and proximity of people to mosquito breeding sites. Malaria causes high fever and flu-like symptoms and can be fatal if untreated, with young children in Africa being most at risk of death. Controlling malaria involves reducing mosquito breeding grounds, using bed nets and insect repellents, and prompt treatment with quinine, which is derived from the cinchona plant. Community cooperation in cleaning up sources of standing water is important for prevention.Malaria Essay

Plasmodium falciparum is a protozoan parasite and the most common, virulent, and deadly cause of malaria in humans. It is transmitted via the bites of infected female Anopheles mosquitoes. P. falciparum's lifecycle involves two hosts as it infects liver cells and red blood cells in humans. Destruction of red blood cells causes symptoms and can be fatal. Malaria disproportionately impacts sub-Saharan Africa and poses a major public health challenge.Epidemology and control of protozoan parasite

- Epidemiology is the study of patterns, causes and effects of health and disease conditions in defined populations. It identifies risk factors and targets for preventive healthcare.
- Major parasitic diseases that are epidemic worldwide include malaria, leishmaniasis, schistosomiasis, lymphatic filariasis, and those caused by protozoan parasites like Plasmodium, Leishmania, Giardia, Entamoeba and Trypanosoma.
- Parasitic diseases disproportionately impact developing nations and vulnerable groups like children and pregnant women. Effective control requires understanding transmission patterns and applying preventive measures.Elephantiasis presentation1

Filariasis is caused by microscopic filarial worms transmitted through mosquito bites. The worms live and breed in the lymphatic vessels, causing swelling, pain, and permanent damage. Symptoms appear months after infection and include swelling of the limbs, breast, and genitals. Over a billion people are at risk of infection, with millions seriously affected across tropical regions of Africa, Asia, and the Pacific. Treatment involves medicines to kill the adult worms and prevent further spreading, but the effects of elephantiasis may be permanent. Prevention focuses on avoiding mosquito bites through protective clothing, nets, and repellents, as well as reducing mosquito habitats near homes.More from sarah marks (10)

The document discusses several hypotheses for what caused the mass extinction of megafauna (large animal species) at the end of the Little Ice Age period between 1300-1850 AD. The main hypotheses presented are:
1) "Overkill" - Early human hunters in North America over-hunted megafauna species when they first arrived, driving many to extinction.
2) "Overchill" - Rapid climate changes at the end of the ice age, particularly a cold snap between 12,900-11,500 years ago, stressed megafauna populations and habitats leading to widespread die-offs.
3) "Overill" - A virulent "hyperdisease" brought by the first humansChild Soldiers

Antarctica is important for several reasons:
1) It stores minerals and resources that may be needed in the future like oil, gold, and coal.
2) It contains 75% of the Earth's fresh water.
3) It reflects heat from the sun, helping to reduce global warming.
There are arguments both for and against developing Antarctica. Those for development say its resources could help address issues like rising oil prices and food shortages. Those against say Antarctica should be preserved as the world's last untouched wilderness and developing it could harm wildlife and the environment. The future of Antarctica is debated between prioritizing protection versus sustainable use of its resources.M A L A R I A Y E A R9

- 3. Why does it matter? Malaria kills a child in Africa every 30 seconds. Thats over one million lives lost every single year.
- 4. What causes Malaria? Symptoms of malaria include fever, headache, and vomiting, and usually appear between 10 and 15 days after the mosquito bite. If not treated, malaria can quickly become life-threatening by disrupting the blood supply to vital organs. In many parts of the world, the parasites have developed resistance to a number of malaria medicines. Key interventions to control malaria include: prompt and effective treatment with artemisinin-based combination therapies; use of insecticidal nets by people at risk; and indoor residual spraying with insecticide to control the vector mosquitoes.
- 5. Causes of Malaria is caused by a parasite called Plasmodium, which is transmitted via the bites of infected mosquitoes. In the human body, the parasites multiply in the liver, and then infect red blood cells. DISTRIBUTION OF DISEASE- At low altitudes During hot seasons In places where the Anopheles mosquito is able to breed in fresh water Where the environment provides water, vegetation, temperature
- 6. Malaria is especially a serious problem in Africa, where one in every five (20%) childhood deaths is due to the effects of the disease. An African child has on average between 1.6 and 5.4 episodes of malaria fever each year. And every 30 seconds a child dies from malaria.
- 8. Malaria hits poor people the hardest because it makes people so sick that they cant work. This means they are likely to face even more poverty. Using insecticide treated bed nets can reduce episodes of malaria in children by half and deaths from malaria in children by one fifth
- 9. What can we do to help? Incredibly, malaria is actually a disease thats cheap and easy to prevent which means you really can help to save lives. Your cash can help to deliver a package of intervention, including bed nets, which will work to protect thousands of children and families across Africa from malaria. 贈5 could buy a malaria bed net, distribute it to someone that needs it and make sure that they are educated on the importance of using it.
