Reason:
First, with the increase of age, the immunity of the elderly is weakening, and the body defense line is easily broken by viruses and bacteria.
Second, for the elderly, after being infected by viruses or bacteria, the incidence of autoimmune increases, making it easier to have inflammatory reactions.
Third, the vast majority of the elderly have basic diseases, such as cardiovascular and cerebrovascular diseases including hypertension, or chronic lung diseases, or diabetes, chronic liver diseases, kidney diseases, tumors, immune dysfunction and so on. If infected with the virus, it will lead to more serious symptoms of the original disease or more prone to complications.
Therefore, the elderly should not take it lightly, and pay attention to strengthening protection in the near future to prevent infection.

What if the elderly are infected with COVID-19?

1、? Increase protein and calories of low-weight elderly people.
At present, the biggest threat to COVID-19 is still the elderly. The average age of inpatients in a mainstream hospital in Hong Kong 174 COVID-19 is 82.5 years old. The risk of death caused by malnutrition, low body mass index (less than 16.5kg/m2) and age ≥75 years increased by 1.7, 1.2 and 5.2 times respectively.
If there are elderly people over 75 years old who are underweight and have a body mass index below 18.5kg/m2 (weight kg/ height m square), they must eat more protein. If the elderly have a bad appetite, you can add minced meat to the porridge, or add an extra box of milk/yogurt. If lactose is intolerant, you can supplement 20~30g protein powder every day.
2、? Vitamins a, d, zinc and selenium
Among the patients admitted to hospital because of COVID-19, the proportion of vitamin A, D, zinc and selenium deficiency is about 50%. Supplementing these trace elements can help the body control inflammation.
Be "lewd" when eating. Carrots, broccoli and spinach, these dark vegetables should be eaten more. They are rich in β-carotene, which can be converted into vitamin A in vivo, improving the secretion function of respiratory mucosa epithelium.
Vitamin D can not only maintain healthy bones, but also improve the ability of macrophages to swallow viruses and bacteria, and help the body resist inflammation. Get more sunshine and eat some foods rich in vitamin D, such as salmon, eggs and mushrooms.
The diet should be as balanced and diverse as possible. People who often eat takeout should add a multi-dimensional mine every day.
3、? Resist inflammation
What I fear most is not weak immunity, but unbalanced immunity, poor resistance and too strong inflammatory reaction in the body.
This kind of person usually has a cold and often suffers from autoimmune diseases such as rhinitis and rash. Moreover, COVID-19's brain fog fatigue and other sequelae often happen to them.
Hong Kong doctors' advice on immune imbalance is to supplement fish oil, which can help the body recover and reduce the duration of symptoms.
We believe that high pressure broke the immune defense of modern people. Our body has its own anti-inflammatory hormone-cortisol. It can also inhibit excessive inflammation, so glucocorticoid is used for anti-inflammation in COVID-19.

For the elderly, when they have a fever, they should also pay attention to other symptoms. They need to see a doctor if they have the following conditions.
-I have a terrible headache
-accompanied by a rash, especially a rash that quickly worsens.
-photophobia
-When you lean forward, if you have neck stiffness and pain.
-Abnormal mental state, such as gibberish and confusion.
-Persistent vomiting
-Chest pain or dyspnea
-Abdominal pain or dysuria
epileptic seizure
Really? Not terrible, do a good job of protection, inoculate Y seedlings normally, and face it with a normal heart.
I wish you all the best, get through the cold winter and welcome the spring.
