Seasonal influenza is a viral respiratory infection that affects the nose, throat, bronchi and, occasionally, the lungs. Infection usually lasts for about a week and is characterized by sudden onset of high fever, aching muscles and joints, headache and severe malaise, non-productive cough, sore throat and rhinitis.

Seasonal influenza is caused by human types of influenza viruses – influenza B, C and few sub-types of A – which circulate worldwide and can affect people in any age group. They are transmitted easily from person to person via droplets and small particles produced when infected people cough or sneeze.

The time from infection to illness is about 2 days. Most infected people recover within 1 to 2 weeks without requiring medical treatment. However, in high risk groups, including the very young, the elderly, and those with serious medical conditions, infection can lead to severe complications of the underlying condition, pneumonia and death. To prevent transmission, people should cover their mouth and nose when coughing and wash their hands regularly.

Influenza tends to spread rapidly in seasonal epidemics. Influenza epidemics can take an economic toll through lost workforce productivity and strained health services.

The most effective way to prevent influenza is vaccination. Safe and effective vaccines are available, and have been used for more than 60 years. Antiviral drugs are available for treatment, and may reduce severe complications and deaths. Ideally they need to be administered within 48 hours of the onset of symptoms although influenza viruses can develop resistance to the drugs.

Seasonal influenza is a viral respiratory infection that circulates in all parts of the world. It causes illnesses that range in severity from mild to severe. Influenza can cause major complications or death, particularly among high-risk groups including young children (6-59 months old), older adults (above 65 years), pregnant women, health workers and those with chronic medical conditions.

To support Member States in preparing for this winter season 2021-2022, the WHO Regional Office for the Eastern Mediterranean is providing these information resources for the benefit of high-risk groups and the general public. They include updated information on the disease, its modes of transmission and preventive measures that can be followed including the influenza vaccine. These materials are available in different formats including posters, Q&As, and videos. While the materials are available in Arabic, English and French, Member States can translate them into other local languages as needed.

On the 7th of April every year, World Health Day is celebrated in the Eastern Mediterranean Region and across the world. This has always been an opportunity to highlight an important public health issue and to promote discussion and debate of various aspects of prevention and promotion of health. This year’s World Health Day 2004 highlights road safety with the slogan “Road safety is no accident”.

Globally, the burden of disease due to injuries has increased from about 12% in 1999 to 15% in 2000 and is expected to rise even further by the year 2020. Road traffic injuries in particular are on the rise and the situation is expected to get worse in the coming years. By 2020 road traffic injuries are forecast to rise from the 9th to the 3rd leading cause of disability adjusted life years (DALYs) lost . It is estimated that by 2020 road traffic injuries will account for about 2.3 million deaths a year, almost double the current burden of mortality of 1.2 million deaths each year. The worrisome aspect is that 90% of these deaths are expected in the less motorized countries.

In the countries of the Eastern Mediterranean Region, the risk of death and disability due to road traffic accidents generally increases with increasing per capita income. Risk of death due to road accidents in the Region, according to available data, ranges from about 8 deaths per 100 000 population in Yemen to 24 deaths per 100 000 population in Oman. Death rates per 10 000 vehicles are highest in the Syrian Arab Republic with 36 deaths/10 000 vehicles and lowest in Bahrain with 3 deaths/10 000 vehicles. However, if these figures are composed clearly with those of a developed country like UK, which has 1.5 deaths/10 000 vehicles, clearly people in our Region are more likely to die because of road traffic accidents. According to the World Health Report 2003 a total of 132 000 deaths occurred in 2002 in the Eastern Mediterranean Region because of road traffic accidents alone.

More disturbing still is that the most affected road users in the Region are pedestrians, cyclists and public transport users. Road traffic injuries are the second leading cause of death among children and people of working age. Injuries and disabilities, which result from road traffic accidents, have enormous economic and social consequences for the injured person, the family, the community and the country. They are estimated to cost governments in developing countries between 1% and 2% of GNP annually. This is a loss of about US$ 520 billion every year, more than the total development assistance received worldwide for developing countries. The World Bank estimates that in 1999 alone the cost incurred to the governments in the Eastern Mediterranean Region by road traffic accidents was more than US$ 7.5 billion.

Road traffic injuries and deaths can be prevented. Many effective strategies have been identified and implemented in developed countries and a slow but steady decline has been noted in these countries. The type of road traffic injuries in developing countries, however, differs significantly from those in the developed world. Problems such as poor data, low political priority, risky behaviour by road users, lack of intersectoral coordination, contending economic and political interests in public road transport, poor roads and even poorer law enforcement, set the scene for an unprecedented co-influence of risks on the roads. As a result, prevention strategies, technologies and policies cannot simply be transplanted from developed countries to the developing world.

Nevertheless, this gloomy picture should not, in any way, deter us from making a fitting response in order to alleviate the sufferings of the people of the Region on the one hand and to prevent economic and social loss on the other. The World Health Organization, realizing the critical nature of the problem, is endeavouring to mobilize governments, organizations and communities to effectively tackle this problem. The theme of “Safe Roads” was selected for the World Health Day campaign 2004 with the aim of generating interest among the different stakeholders, communities and organizations in developing the strategies needed to combat this menace.

The World Report on Road Traffic Injury Prevention, a joint WHO and World Bank activity, is also being launched on World Health Day. The purpose of the report is to present a comprehensive assessment of what is known about the magnitude and impact of this multi-sectoral problem and the intervention strategies available. At the regional level, several countries in the Region have already initiated action to tackle the problem and reduce the burden of death and disabilities caused by road traffic injuries, including Djibouti, Egypt, Islamic Republic of Iran, Oman and Saudi Arabia.

World Health Day is not merely a celebration event but a commitment towards a cause, dedication to an objective and a promise for a better future. Prevention of road traffic injuries relies on different sectors: government, nongovernmental organizations, media, private business, local communities, schools, transport and health sector. Raising the level of awareness of all those involved is a prerequisite to road traffic injury prevention. There should be a focus on road users’ behaviour, on improved infrastructure and safety and maintenance of vehicle. It is crucial to obtain a commitment of individuals to their own safety and that of their passengers and other road users, including pedestrians, and to the possibility of generating new solutions by tapping into the potential in the community.

The launch of World Health Day is only the beginning of a year-long global campaign on road traffic injury prevention. Let us all join hands so that children and parents can return to their homes at the end of each and every day is safety. Together, I am sure, we can make a difference.

The theme of World Health Day this year is “International Health Security” and the slogan “Invest in health, build a safer future” is of particular relevance to our region.

The WHO Eastern Mediterranean Region is prone to emergencies, both natural and manmade. Currently, several countries are coping with conflict and the aftermath of natural disaster. A number of diseases threaten health in the Region, including avian influenza, malaria and HIV/AIDS, while environmental degradation increases daily.

WHO is working in close collaboration with the many stakeholders concerned to address such challenges in order to achieve collective security from disease and protect global health. We must continue to expand our horizons, to work not only with governments but also international organizations, civil society and the business community if we are to face together the various health and security challenges.

Threats to health know no borders. In an age of global trade and travel, new and existing diseases can cross national borders and threaten our collective security with ease.
Only through strong collaboration among developed and developing countries, can we contain this threat––collaboration focused on information sharing, using all the communication channels available, and strengthening of the public health system and of surveillance.

The revised International Health Regulations will come into force this June. Through the implementation of the Regulations we can together build and strengthen effective mechanisms for outbreak alert and response at both national and international levels.

International health security is everyone’s dream. To become a reality it requires investment on our part. Let’s all work together to invest in health and build a safer future.

La Journée mondiale de la Santé 2014 a pour thème les maladies à transmission vectorielle et le slogan est: Petits mais dangereux.

Que sont les vecteurs?

Les vecteurs sont des petits organismes porteurs de maladies qu'ils transmettent d'une personne à une autre et qu'ils propagent d'un endroit à un autre. Ils peuvent poser un risque pour notre santé, à la maison et lors de voyages.

Pourquoi les maladies à transmission vectorielle?

Chaque année plus d’un million de personnes meurent de maladies à transmission vectorielle comme le paludisme, la dengue, la schistosomiase et la fièvre jaune. Et suite à une infection, davantage de personnes se retrouvent atteintes de maladies chroniques et de déficiences.

Plus de la moitié de la population mondiale est exposée au risque de contracter ces maladies. Avec l’augmentation des voyages, du commerce et des migrations, le nombre de personnes à risque s’accroît.

Les maladies à transmission vectorielle causent d’importantes souffrances à des millions de personnes.

Ces maladies ont non seulement des conséquences profondes sur la santé des individus mais elles constituent également une entrave majeure à la réduction de la pauvreté et au développement socioéconomique.

Il est temps que le monde s’intéresse à la menace que constituent les vecteurs et les maladies à transmission vectorielle.

La Journée mondiale de la Santé 2014 est un évènement permettant d’attirer l’attention du monde entier sur cette menace.

Campagne médiatique

La campagne de la Journée mondiale de la Santé 2014 mettra en lumière certains des vecteurs les plus connus - comme les moustiques, les phlébotomes, les insectes, les tiques et les gastéropodes - responsables de la transmission de nombreux parasites et agents pathogènes qui attaquent les humains et les animaux.

Objectif global

La campagne vise à sensibiliser sur la menace que constituent les vecteurs et les maladies à transmission vectorielle et à encourager les familles et les communautés à agir pour se protéger. Étant donné que les maladies à transmission vectorielle commencent à se propager au-delà de leurs limites traditionnelles, l'action contre ces maladies doit s'étendre au-delà des pays où elles sont actuellement présentes.

Objectifs et public cible

Les objectifs de santé publique de la campagne sont les suivants :

les familles vivant dans des régions où les vecteurs transmettent des maladies savent comment se protéger ;

les voyageurs savent comment se protéger contre les vecteurs et les maladies à transmission vectorielle lorsqu'ils voyagent dans des pays où elles représentent une menace pour la santé ;

dans les pays où les maladies à transmission vectorielle constituent un problème de santé publique, les ministères de la Santé mettent en place des mesures visant à améliorer la protection de leurs populations et ;

dans les pays où les maladies à transmission vectorielle représentent une menace émergente, les autorités sanitaires collaborent avec les autorités chargées des questions environnementales ainsi que les autorités compétentes au niveau local et dans les pays voisins en vue d'améliorer la surveillance intégrée des vecteurs et de prendre des mesures pour prévenir leur prolifération.

Messages principaux

Les insectes, moustiques, mouches, tiques et autres, ainsi que les gastéropodes d’eau douce peuvent transmettre des maladies susceptibles d’être graves et d’entraîner la mort.

Des maladies comme le paludisme, la dengue, la leishmaniose et la fièvre jaune sont évitables, elles ont pourtant un impact lourd parmi certaines populations les plus pauvres du monde.

Plus de la moitié de la population mondiale est exposée au risque de ces maladies. Avec l’augmentation des voyages, du commerce et des migrations, le nombre des personnes vulnérables s’accroît.

Vous pouvez vous protéger ainsi que votre famille en prenant de simples mesures, comme dormir sous une moustiquaire, porter des chemises à manches longues et des pantalons et appliquer des produits répulsifs.
