borne diseases Vectors are living organisms that can transmit infectious diseases between humans or from animals to humans.
Many of these vectors are bloodsucking insects, which ingest disease producing microorganisms during a blood meal from an infected host (human or animal) and later inject it into a new host during their subsequent blood meal. Mosquitoes are the best known disease vector. Others include ticks, flies, sandflies, fleas, triatomine bugs and some freshwater aquatic snails. Vector are illnesses caused by pathogens and parasites in human populations. Every year there are more than 1 billion cases and over 1 million deaths from vector such as malaria, dengue, schistosomiasis, human African trypanosomiasis, leishmaniasis, Chagas disease, yellow fever, Japanese encephalitis and onchocerciasis, globally. Vector account for over 17% of all infectious diseases. Distribution of these diseases is determined by a complex dynamic of environmental and social factors. Globalization of travel and trade, unplanned urbanization and environmental challenges such as climate change are having a significant impact on disease transmission in recent years. Some diseases, such as dengue, chikungunya and West Nile virus, coach outlet 2015 are emerging in countries where they were previously unknown. Changes in agricultural practices due coach outlet locations 9 news to variation in temperature and rainfall can affect the transmission of vector . Climate information can be used to monitor and predict distribution and longer term trends in malaria and other climate sensitive diseases. providing the best evidence for controlling vectors and protecting people against infection; providing technical support and guidance to countries coach bags on sale so that they can effectively manage cases and outbreaks; supporting countries to improve their reporting systems and capture the true burden of the disease; providing training on clinical management, diagnosis and vector control with some of its collaborating centres throughout the world; and developing new tools to combat the vectors and deal with the disease, for example insecticide products and spraying technologies. A coach outlet sale kitchenaid crucial element in vector is behavioural change. WHO works with partners to provide education and improve awareness so that people know how to protect themselves and their communities from mosquitoes, ticks, bugs, flies and other vectors.
For many diseases such as Chagas disease, malaria, schistosomiasis and leishmaniasis, WHO has initiated control programmes using donated or subsidized medicines. Access to water and sanitation is a very important factor in disease control and elimination. WHO works together with many different government sectors to control these diseases.
