World health day is celebrated on 7th of April every year. It is celebrated to mark the birthday of the World Health Organization. 2014 is the 66th anniversary of WHO. WHO was commemorated in the year 1948 since when they focussed on different themes to protect the health of the people worldwide. Through effective campaigns and preventive measures, WHO steps forward to eradicate the dreadful diseases depleting human lives. Past few years, the themes of WHO on the World Health Day were,
Apart from these themes, WHO has also played a major role in providing protection and preventive measures for global polio eradication, safe motherhood and road safety.
The goal of World Health Day 2014 campaign is to provide awareness against vector borne diseases. The campaign also advocates for health authorities in countries where vector-borne diseases are apublic health?problem or emerging threat, to put in place, measures to improve surveillance and protection
The goal of World Health Day 2014 campaign is to provide protection from vector-borne diseases, especially for families living in areas where diseases are transmitted by vectors, and travellers to countries where they pose a health threat. WHO will focus on some of the commonly known vectors like mosquitoes, sand flies, bugs, ticks and snails ? responsible for transmitting a wide range of illnesses.
Vector-borne diseases are illnesses caused by these pathogens and parasites in human populations. They are most commonly found in tropical areas and places where access to safe drinking-water and sanitation systems is problematic. Many of these vectors are bloodsucking insects, which ingest disease-producing micro organisms during a blood meal from an infected host (human or animal) and later inject it into a new host during their subsequent blood meal.
Vector-borne diseases account for over 17% of all infectious diseases. Distribution of these diseases is determined by many 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. Changes in agricultural practices due to variation in temperature and rainfall can affect the transmission of vector-borne diseases. Climate information can be used to monitor and predict distribution and longer-term trends in malaria and other climate-sensitive diseases.
Every year there are more than 1 billion cases and over 1 million deaths from vector-borne diseases. The most deadly vector-borne disease, malaria, caused 660 000 deaths in 2010. Most of these were African children. More than 2.5 billion people in over 100 countries are at risk of contracting dengue alone. Many of these diseases are preventable through informed protective measures.
