Dr. I. Bhavadasan Namboothiri releasing the news letter for public awareness on World Health Day 2014.

This World Health Day, 7 April 2014, the World Health Organisation turns the spotlight on the serious and increasing threat of vector-borne diseases, with the slogan “Small bite, big threats”. According to WHO reports, more than half the world’s population is at risk from diseases such as malaria, dengue, leishmaniasis, Lyme disease, schistosomiasis, and yellow fever, carried by mosquitoes, flies, ticks, water snails and other vectors. Every year, more than one billion people are infected and more than one million die from vector-borne diseases.

The Organization also emphasizes that these diseases are entirely preventable.

“Simple, cost-effective interventions like insecticide-treated bed nets and indoor spraying have already saved millions of lives,” says Dr Margaret Chan, WHO Director-General. “No one in the 21st century should die from the bite of a mosquito, a sandfly, a blackfly or a tick.”

Schistosomiasis, for example, transmitted by water snails, is the most widespread of all vector-borne diseases, affecting almost 240 million people worldwide. Children living and playing near infested water are particularly vulnerable to this disease which causes anaemia and a reduced ability to learn. Schistosomiasis can be controlled through regular mass treatment of at-risk groups with a safe, effective medicine, as well as improving access to safe drinking water and sanitation.

Within the past two decades, many important vector-borne diseases have also re-emerged or spread to new parts of the world. Environmental changes, a massive increase in international travel and trade, changes in agricultural practices and rapid unplanned urbanization are causing an increase in the number and spread of many vectors worldwide and making new groups of people, notably tourists and business travellers, vulnerable.

Mosquito-borne dengue, for example, is now found in 100 countries, putting more than 2.5 billion people – over 40% of the world’s population – at risk. Dengue has recently been reported in China, Portugal and the state of Florida, in the United States of America. Reports from Greece say that malaria has returned there for the first time in 40 years. This highlights the continual threat of reintroduction and the need for continued vigilance to ensure that any malaria resurgence can be rapidly contained.

On World Health Day 2014, WHO is calling for a renewed focus on vector control and better provision of safe water, sanitation and hygiene “ key strategies outlined in WHO’s 2011 Roadmap for the control, elimination and eradication of neglected tropical diseases, which sets targets for the period 2012-2020.”
