The new coronavirus epidemic is getting more and more serious, and every day we see more and more confirmed cases, with the elderly being the main target of this virus attack. So what should older people with low resistance do to keep themselves healthy? For elderly people with underlying diseases, they should control their risk factors and take their medications regularly. For example, elderly people with high blood pressure and diabetes should regularly monitor their blood pressure and blood sugar levels to ensure that they fluctuate within a normal range. Take your medications on time and as prescribed by your doctor. Prevent changes in blood pressure, blood glucose, lipids and other risk factors due to unauthorized discontinuation of medications or irregular medications that do not meet the blood concentration standards, which may lead to low body immunity and lead to virus transmission. The next step is to strengthen personal protection. Avoid going to crowded public places and wear a mask when you go out. Wash your hands regularly with soap and water or alcohol-based hand sanitizer, and do not touch your eyes, mouth or nose with dirty hands. The first thing you should do when you get home after going out is to take off your mask and wash your hands. Don’t touch elevator buttons and door handles with clean hands, etc. It’s best to use a clean piece of toilet paper across your palm before touching these public facilities, and discard the contaminated tissue after touching. Don’t spit anywhere, and cover your mouth and nose with tissues or elbow sleeves when sneezing or coughing. Strengthen exercise, regular work and rest, and keep indoor air circulation. Older people should also avoid contact with wild animals. Seniors should avoid places with a lot of wild animals such as vegetable markets or animal farms. Do not eat wild animals, make sure the food is fully cooked when eating meat and eggs and milk, and it is best to have one set of utensils to avoid cross-contamination. Finally, elderly people have a weak resistance, so it is important to ensure an effective and reasonable safety distance when talking to people and to wear a mask to avoid droplet transmission. Generally speaking, it is best to talk to people one meter away from each other and not to have static distance contact. The best way to prevent viral infection is to stay away from home, achieve home isolation and wait for the epidemic to pass.
