The elderly is classified as "very vulnerable" among various other age groups in societies, because they are most vulnerable to chronic diseases, their complications, deterioration of functional ability, and disability, and because of discrimination against the elderly and its negative consequences for them.


As healthcare improves, so does the number of elderly people increase year by year, and so does their needs, and so does their contributions to the world. The composition of the world population has changed dramatically in recent decades, between 1950 and 2010, average life expectancy worldwide increased from 46 to 68 years, and in 2015, the World Health Organization report indicated that the global average life expectancy reached (71.4) years. - 69.1 for males and 73.8 for females. This is the fastest increase since the 1960s.


The same report also indicates that more than 700 million people in the world are over the age of 60; East and Southeast Asia is home to the largest number of elderly people (261 million), followed by Europe and North America (more than 200 million), and that by 2050 they will number more than two billion. According to the United Nations, all regions of the world will witness an increase in the size of the oldest population between 2019 and 2050. Globally, the number of people aged 60 years or over is expected to increase by 46 percent (from 962 million to 1.4 billion) outnumbering young adults, as are children under the age of 10.


The global pandemic, Covid-19, has affected all walks of life, the most important of which are economic, health and social. The health effects of the pandemic have been severe and deadly on certain groups of people, called those with high risks, namely children, the elderly, pregnant women and those suffering from one of the chronic debilitating diseases that affect their immunity, such as diabetes, high blood pressure, cardiovascular disease, etc.


A recent study conducted by the London School of Economics and University College London and published in the Guardian newspaper indicated that the elderly, who are usually weak in structure and suffer from most chronic diseases of the age, have low immunity and have rapid and severe disease infections, as the Covid-19 pandemic has caused many risks. For this category of elderly. The results of this study indicated that 75 percent of coronavirus-related deaths in elderly care facilities worldwide are due to elderly people. This makes it imperative to rethink the relationship of the elderly with such emergency epidemics and to examine the impact of the Corona pandemic on them in particular.


A Coronavirus patient is known to have three symptoms: fever, persistent cough, and shortness of breath. But the elderly, who are the age group most at risk of severe complications or death from this condition, may not have any of these three symptoms, but rather have a number of other "atypical" symptoms, which complicates efforts to ensure that they receive appropriate treatment.
