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.

The theme of World Health Day 2014 is vector-borne diseases, under the slogan "Small bite: big threat".

What are vectors?

Vectors are small organisms that carry diseases and spread them from person to person and place to place. They can put our health at risk, at home and when we travel.

Why vector-borne diseases ?

Every year more than one million people die from vector-borne diseases, such as malaria, dengue, schistosomiasis, leishmaniasis and yellow fever. Many more people are left with chronic illness and disabilities as a result of infection.

More than half the world’s population is at risk of these diseases. Increased travel, trade and migration is increasing the number of people at risk.

Vector-borne diseases cause immense suffering for millions of people.

Not only do these diseases have a profound effect on people’s health but they are a serious impediment to poverty reduction and socioeconomic development.

It is time to draw global attention to the threat posed by vectors and vector-borne diseases.

World Health Day 2014 is an event to draw global attention to these threats.

Media campaign

Take simple measures to protect yourself from vector-borne diseasesTake simple measures to protect yourself from vector-borne diseasesThe 2014 campaign will highlight some of the most commonly known vectors – such as mosquitoes, sandflies, bugs, ticks and snails – responsible for transmitting a wide range of parasites and pathogens that attack humans or animals.

Overall goal

The campaign aims to raise awareness of the threat posed by vectors and vector-borne diseases and to encourage families and communities to take action to protect themselves. As vector-borne diseases begin to spread beyond their traditional boundaries, action needs to be expanded beyond the countries where these diseases currently thrive.

Objectives and target audiences

The public health objectives of the campaign are to ensure that:

families living in areas where diseases are transmitted by vectors know how to protect themselves;

travellers know how to protect themselves from vectors and vector-borne diseases when travelling to countries where these pose a health threat;

in countries where vector-borne diseases are a public health problem, ministries of health put in place measures to improve the protection of their populations; and

in countries where vector-borne diseases are an emerging threat, health authorities work with environmental and relevant authorities locally and in neighbouring countries to improve integrated surveillance of vectors and to take measures to prevent their proliferation.

Key messages

Mosquitoes, flies, ticks, bugs and freshwater snails can spread diseases that cause serious illness and death.

Diseases such as malaria, dengue, leishmaniasis and yellow fever are preventable, yet they have the biggest impact on some of the world’s poorest people.

More than half of the world’s population is at risk of these diseases. Increased travel, trade and migration make even more people vulnerable.

You can protect yourself and your family by taking simple measures that include sleeping under a bednet, wearing a long-sleeved shirt and trousers and using insect repellent.
