1, turning to lifestyle-related diseases. Great changes have taken place in global health in the last century. Decades ago, infectious diseases such as malaria and Ebola virus were the main medical problems faced by developing countries. However, more and more developed countries emphasize prevention, vaccination and assistance programs, which has reduced the spread of these infectious diseases. In the past decades, even in developing countries, lifestyle-related diseases have changed. Cancer, heart disease and mental illness are expected to surpass malnutrition and infectious diseases in children and become one of the biggest diseases in the world. In recent years, nurses in developed countries have seen the change of this lifestyle disease, but with the increase of global wealth, this disease is now more and more common in underdeveloped countries. This shows that health professionals must cope with the changes in global health patterns, because lifestyle-related diseases cannot be cured or vaccinated. Dealing with problems like heart disease and cancer requires the education of people all over the world. If we want to prevent these diseases, we must understand their causes.
2. The continued spread of HIV/AIDS. Middle and high income countries are mainly controlled by the spread of HIV/AIDS. In order to prevent HIV from becoming AIDS, public health activities and preventive treatment that emphasize safer sex are all part of reducing the spread of the disease. However, low-income developing countries are still affected by HIV/AIDS. In developing countries, especially in sub-Saharan Africa, AIDS is still an epidemic, and nearly 66% of new infections occur in sub-Saharan Africa. Although many transnational, governmental and non-governmental organizations are concerned about preventing the spread of HIV/AIDS, it is still difficult to stop the spread of HIV/AIDS in these countries, especially those with unstable political climate. In fact, soldiers are still one of the main media of HIV/AIDS in war-torn countries. According to World Watch, nearly 20% of soldiers in sub-Saharan Africa are infected with HIV/AIDS, which constitutes the majority of the infected population in these areas.
3. The global antibiotic-resistant diseases have caused many terrible diseases in the past ten or twenty years, including SARS, avian influenza, West Nile virus, Ebola virus and infectious virus. As the world can continue to develop and become more interconnected through convenient air travel, highly infectious diseases remain a great threat to the whole world and even to countries with weak health infrastructure. Although the world's first medical care can alleviate bird flu, developing countries often cannot obtain advanced medical equipment, resulting in higher mortality. Drug-resistant strains of these diseases are also a problem worthy of consideration. Excessive use of antibiotics may lead to the development of super bacteria, which can resist common antibiotics. If highly advanced, infectious and drug-resistant diseases spread around the world, the impact may be devastating, and even the world's first country may not be able to cope with the treatment needed to save lives. Preventive measures include closely monitoring the epidemic situation and studying the fight against drug-resistant epidemic situation, and the government taking action to reduce the spread of the epidemic situation.
4. Prevent gaps. Developing countries often lack infrastructure, so it is necessary to provide clean water, build sewage channels and ensure good hygiene habits. Although our society is progressing, nearly half of the population has no toilets and clean water. The best way to solve this problem is to increase investment in developing countries. Government funds to provide clean drinking water and sanitation facilities for low-income countries can produce significant benefits. If we want to improve the health level of the global population, we must provide people in these countries with everything they need for a stable environment and sustainable development. Whether you can donate a few dollars to an organization like UNICEF to help low-income countries provide sanitation facilities or help spread awareness of these problems, you should do your best to help alleviate and solve these problems.
