Why are older people more at risk

As we learn more about COVID-19, It's increasingly clear that your risk of severe illness and death increases with age. Children under nine years of age seem to be largely unaffected, either with no or mild symptoms. None have died as a result of the infection.

When we know more about COVID-19, it's becoming increasingly clear that with age the risk of serious illness and death increases. Children under the age of nine are largely unaffected, with no or moderate signs, either. None have died from the infection.


People over the age of 80 years and those with chronic diseases are the most vulnerable. For those over 80, approximately 15 percent of those infected will die. The death rate starts to Increase for those over 50 years of age. Those under 50 years who are infected have a death rate of 0.2-0.4 percent, while for those 50-59 years It's 1.3 percent.

The most affected are people over 80 years of age, and those with chronic diseases. Approximately 15 per cent of those infected will die for those over 80. The mortality rate for people over 50 years of age continues to increase. People under the age of 50 that are contaminated have a mortality risk of 0.2-0.4 per cent, while it is 1.3 per cent for those 50-59 years.


For those 60-69 years it's 3.6 percent, for 70 to 79 year olds it's 8.0 percent and for those over 80 years of age It Is 14.8%. A similar picture is emerging when looking at the increased risk of severe illness and death of those with underlying conditions. The death rate for those with no underlying chronic conditions is approximately 1 percent. For those with cardiovascular (heart) disease the death rate is 10.5 percent, for diabetes it's 7.3 percent.chronic respiratory disease (such as asthma and chronic obstructive pulmonary disease) has a 6.3 percent death rate, for hypertension (high blood pressure) it's 6.0 percent and cancer is 5.6 percent.

People under the age of 50 that are contaminated have a mortality risk of 0.2-0.4 per cent, while it is 1.3 per cent for those 50-59 years.Among those with cardiovascular (heart) disease, the death rate is 10.5%, among diabetes it is 7.3%. Chronic pulmonary disease (such as asthma and chronic obstructive lung disease) has a death risk of 6.3%, for hypertension ( high blood pressure) it is 6.0% and cancer is 5.6%.


The likelihood of having chronic conditions increases markedly as you age. Four in five Australians aged 65 years and over have at least one chronic condition. But the presence of chronic conditions only partially explains the high death rate in older people.

When you age, the risk of developing chronic illnesses rises considerably. Four Australians in five aged 65 and over have at least one medical illness. Yet the presence of medical diseases explains only in part the high mortality rate in older people.


As we age, our immune system weakens. This makes us more vulnerable to infections of all types. And any sort of challenge to the body can do more damage. When the immune system gears up in older people, there is also a higher likelihood of a phenomenon called a cytokine storm. This is where the immune system overreacts and produces too many of the chemicals to fight infection.

The immune system weakens as we age. It leaves us more vulnerable to all forms of infections. And any kind of obstacle can do more harm to the body. There is also a greater risk of a condition called a cytokine storm as the immune system is warming up in older people. It is where the immune system overreacts, and too many chemicals are created to combat infection.


So you get a severe inflammatory reaction which has the potential to cause significant damage in the body, including organ failure. The biggest risk factor for dying of coronavirus is cardiovascular (heart) disease, with a death rate of 10.5 percent. But we don't yet know why. This doesn't mean that infection necessarily causes a heart attack, just that people with underlying heart problems are more likely to become seriously ill and die from complications of coronavirus.

And you get a serious inflammatory response that has the ability to cause significant body damage like organ failure. Cardiovascular (heart) disease is the greatest risk factor for coronavirus dying with a death rate of 10.5 per cent. Yet somehow, we don't know why. This does not mean the inflammation triggers a heart attack, only that people with underlying heart issues are going Become more likely to experience serious illness and die from coronavirus complications.


The increased risk of severe disease for those with diabetes, such as actor Tom Hanks, may be easier to understand. Diabetes depresses immune function and makes it harder to fight off viral infections.Elevated glucose (blood sugar) levels in people with diabetes may also provide a more ideal environment for viruses to thrive.

In those with diabetes, such as actor Tom Hanks, the elevated risk of serious disease can be easier to recognize. Diabetes depresses immune function and makes fighting against viral infections more difficult. Elevated levels of glucose ( blood sugar) in people with diabetes can also provide an optimal environment for viruses to flourish.


The increased risk of severe disease from COVID-19 in people with chronic respiratory illness such as asthma and lung disease (known as chronic obstructive pulmonary disease, or COPD) is perhaps the clearest, especially if your illness is not well controlled.

The increased risk of serious COVID-19 disease in persons with chronic respiratory disease such as asthma and lung disease (known as chronic obstructive pulmonary disease, or COPD) may be the clearest, particularly if the disease is not well managed.


Respiratory conditions such as uncontrolled asthma, which causes inflammation of the airways - are likely to be exacerbated by infection with COVID-19, which also targets the airways.

Respiratory problems like uncontrolled asthma causing airway inflammation-are likely to be worsened by COVID-19 infection, which also affects the airways.


If you fall into a vulnerable group, or have close contact with someone who does, be vigilant with hygiene. The government recommends:

If you fall into a vulnerable category, or are in close touch with someone doing so, be careful about hygiene. The Administration recommends:


sanitizing your hands wherever possible, including entering and leaving buildings

using 'tap and pay' to make purchases rather than handling money

traveling at quiet times and trying to avoid crowds

asking public transport workers and taxi drivers to open vehicle windows where possible

regularly cleaning and disinfecting surfaces that are touched a lot.


Wherever practicable, sanitize your hands when entering and leaving buildings

Using 'press and pay' to make transactions and not to treat money

Traveling in the silence and avoiding crowds

Asking public transit staff and taxi drivers to open windows for vehicles where possible

Cleaning and disinfecting surfaces which are handled a lot on a daily basis.


You may even want to limit your public transport use and non-essential travel to reduce your chance of coming into contact with the virus.

You may also want to restrict the use of public transportation and non-essential travel to reduce the chance to come into contact with the virus.


It's also reasonable to ask family or friends not to visit you when they're ill.
Even if you're young and healthy and not feeling particularly at risk of coronavirus, remember you play an important role in stopping the spread of the virus to those more vulnerable.

Asking family or friends not to visit you while they're sick is also fair.
Even if you're young and healthy, and don't feel especially at risk for coronavirus, note that you play an important role in preventing the virus from spreading to the more vulnerable.


Some government are implementing additional measures to reduce the risk of older people becoming infected. In the United Kingdom, the government has indicated that in the coming weeks people aged over 70 could be asked to self-isolate, or reduce their social contact, for up to four months.

The UK government has also asked that no one visits aged care facilities unnecessarily, and that people visiting elderly relatives for essential reasons keep their distance. In the United States, President Donald Trump has urged older Americans to stay home for the next 15 days.

The UK Government has also demanded that no one inappropriately visit aged care facilities, and that people visiting elderly relatives keep their distance for important reasons. President Donald Trump has encouraged older Americans in the US to stay home for the next 15 days.


In Australia, the government has recommended limiting visits to residential care facilities and is likely to announce new measures tomorrow.

The government has proposed limiting access to residential care facilities in Australia, and is expected to announce new legislation tomorrow.


For now, asking older people in the community to take precautionary measures appears to be sensible advice, rather than imposing rules around self-isolation which come with logistical and social consequences.

For the time being, encouraging older people in the group to take precautionary steps seems to be sound advice rather than enforcing guidelines on self-isolation that have practical and social consequences.
