Meta: Global health and health care challenges in recent years have been highlighted by the World Health Organization (WHO). Let’s find out how these problems affect the health sector.
The world is facing many health challenges, from outbreaks of vaccine preventable diseases such as measles and diphtheria, the rise of drug-resistant microorganisms, increased rates of obesity and physical inactivity on health impacts from environmental pollution, climate change and humanitarian crises. To address these and other threats, 2019 is the start of the World Health Organization’s 5-year Strategic Plan – 13th Joint Work Program. focus on three 1 billion targets on all 3 indicators: ensure 1 billion more people benefit from universal health coverage, 1 billion more people protected from medical emergencies and 1 billion more people achieve better mental and physical health. To achieve this goal, health threats from a variety of perspectives need to be addressed. This article will talk about the issues that the World Health Organization and its partners in the health sector need to be concerned about in recent years.
Air pollution and climate change
According to WHO, the level of air pollution remains dangerously high in many parts of the world. New data from WHO shows that 9 out of 10 people who breathe air contain high pollutants. Contaminants with very small size such as PM10 and PM25 in the air can penetrate the respiratory and circulatory system and harm the lungs, heart and brain. The main cause of air pollution is the use of fossil fuels,, causing climate change, affecting health. Projections for the period 2030 to 2050, climate change could cause 250,000 deaths per year from related factors such as malnutrition, malaria, diarrhea, and heat stroke. In 2019, air pollution is considered by WHO as the biggest risk to human health. The alarming estimates that 7 million people die each year from outdoor and household air pollution are linked to diseases like cancer, stroke, heart and lung disease. About 90% of these deaths are in low- and middle-income countries, with large amounts of emissions from industries, transportation, agriculture, and cooking using charcoal.

Non-communicable diseases such as diabetes, cancer and heart disease cause more than 70% of deaths worldwide, equivalent to 41 million people, of which up to 15 million die prematurely within the age of 30 to 69. More than 85% of premature deaths occur in low-income and middle-income countries. Five main risk factors contribute to the increase in these diseases: smoking, less physical activity, harmful alcohol consumption, unhealthy diet and air pollution. These risk factors also exacerbate mental health problems, which can germinate at a young age: Half of all patients with psychiatric illness that started before age 14, however Most of these cases go undetected or treated. Suicide is the second leading cause of death between the ages of 15-19.

Global pandemic flu influenza
The world will face another flu pandemic – the only thing we don’t know yet is when a pandemic happens and how serious it will be. The World Health Organization is constantly monitoring the circulation of influenza viruses to detect potential pandemic strains: 153 research institutes in 114 countries have participated in the global surveillance and response system. Every year, the World Health Organization recommends the strains to be included in the production of flu vaccines to protect people against seasonal flu. In the event of a new influenza strain with pandemic potential, the World Health Organization will form a special partnership with key partners to ensure that people have timely and equitable access to diagnostic services antivirals, vaccines and therapies, especially in developing countries.

Difficult living environment
More than 1.6 billion people (22% of the global population) live in areas of prolonged crisis (with numerous challenges such as drought, famine, conflict and evacuation) and weak health services. Poor access to basic health care services. Fragile habitats exist in most regions of the world – where more than half of the key UN Sustainable Development Goals, including maternal and child health, are not yet covered response. The World Health Organization will continue to work in these countries to strengthen the health system to better prepare for disease detection and response, as well as the ability to provide quality health services high quality, including vaccinations.

Above are detailed information about the challenges facing the global health sector in recent years. Every country government needs to support the health sector to solve these problems as quickly as possible.
