Yuan Lei Small Classroom | Key Points of Protection from Cross Infection

 

 

Now that the epidemic has entered a relatively severe and complex period, the prevention and control of the epidemic is in a critical period, and according to recent clinical data, the spread of the virus seems to have increased. The new coronavirus has 85% homology with SARS, but it is "cunning" than SARS ". Because we don't know exactly where the virus is, there may be many mild cases, similar to a common cold, but the new coronavirus is contagious when it does not have any typical symptoms during the incubation period.

 

To deal with the epidemic, we must grasp two key points, one is early detection, the other is early isolation. The incubation period of the new coronavirus is generally 3-7 days, the shortest is 1 day, the longest is not more than 14 days, and the quarantine observation period is 10 to 14 days. Since the suspected cases have been reported and isolated, it is not terrible. What is terrible is the invisible infection that we do not know yet. Therefore, strict prevention and control should be carried out, and at the same time, each of us should strictly do a good job in cross infection protection.

 

1. Understanding Viral Infectious Diseases Pathways of Virus Transmission

 

A、infectious source

At present, we mainly see pneumonia patients with new coronavirus infection.

 

B、route of transmission

1、It is mainly spread by droplets at close range.

2、The droplets will stay in various places and easily cause indirect transmission, such as: glass, metal (elevator buttons, door handles, etc.), plastic.

3、It may be transmitted by contact, e.g., when the hand touches the source of infection and then rubs the eye or picks the nose, the virus contacts the mucosal cells to complete the infection.

 

2. the right way to protect against cross-infection

1、Try to avoid going out to parties and relatives.

2、The epidemic will continue for some time, so do not travel at present, especially in Wuhan.

3、Do not buy birds of unknown origin, but also try to avoid contact with wild animals, do not eat game, eat more fruits and vegetables.

4、Eat food after it is thoroughly cooked. Avoid raw food and immature animal products, including eggs, milk and meat.

5、Open windows for ventilation, which helps to reduce the amount of viruses that may exist in the room, and also helps to update the indoor air (in addition to being afraid of heat, viruses are also afraid of air circulation)

6、If you want to disinfect your home, you can use alcohol (75% concentration) or 84 disinfectant (if you have neither been in contact with any confirmed or suspected cases recently, nor have you gone out to walk or have dinner, you don't need to be too nervous and don't need special disinfection).

7、If you want to walk your cat and dog, remember to wear a mask. When you get home, you can bathe your cats and dogs thoroughly with the usual bath products (there is no evidence that this coronavirus is contagious to cats and dogs).

8、In order to avoid being infected with virus in delivery and distribution, you can let the delivery or express brother put the goods at the door first, and then take the package into the house when he leaves.

9、After receiving the express, wipe the bag with alcohol first, and then wash your hands after opening it to reduce the risk.

10、Try to wash towels once a day, change sheets, quilts and clothes frequently, and dry them at high temperature when conditions permit.

11、Water cups, tea cups, tableware, etc. should be disinfected at any time after use. You can boil water in a disinfection cabinet or boiling water for 15 minutes. After disinfection, rinse with flowing water.

12、Wash your hands frequently

• You must wash your hands after going to the toilet, before eating, after touching pets, after returning from a trip, and after taking off your mask at home.

• Wash your hands with running water and let the soap or hand sanitizer rub well for no less than 20 seconds.

• If you do not have the conditions to wash your hands when you go out, you can use hand sanitizer.

13、If you must go out under special circumstances, be sure to wear a mask before going out.

14、Before entering the door, shoes should be strictly sprayed and disinfected (especially the soles), and isolated from the house. Because go out shoes may step on the infected person's saliva, vomit, urine, etc., take home easily lead to infection.

 

Key points of 3. workplace protection

1 on the way to work

Take public transportation and wear masks correctly.

2. Into the office building

· Normal body temperature can enter the building to work, and to wash hands in the bathroom;

If the body temperature exceeds 37.2 ℃, please do not work in the building, go home to rest and observe, and go to the hospital if necessary.

3、telephone disinfection

Recommended mobile/landline daily75% alcohol wipe twice, frequent use can be increased to four times.

4、Attend the meeting

Reduce centralized meetings and control meeting time. When the meeting time is too long, open the window for ventilation once.

5、eat lunch

It is recommended to bring your own lunch, reduce going out and avoid dinners.

 

Key points of 4. return protection

A. public transport return

1.Early waiting station

New quarantine measures such as body temperature at airports and stations have led to long security checks. It is recommended to enter the station and wait for the bus in advance.

2、epidemic prevention supplies

Prepare masks, hand sanitizer, napkins and other items in advance, and pay attention to wearing masks correctly during the journey.

 

B, self-driving return trip

1、Avoid peak

Because the outbreak has been introduced around the highway entrance health check policy, may cause traffic congestion, so the return journey as far as possible to avoid peak hours.

2、Expressway service area stop

Highway service areas and rest areas are relatively crowded, and the risk of cross-infection is high. It is recommended to choose a service area with fewer people to stop and take relevant epidemic prevention measures.

 

5. error protection

1、Eating garlic is better than killing virus oral drugs? Fake! Lack of scientific basis and clinical experimental evidence.

2、Nostrils coated with oil does not prevent the virus from entering the body.

3、Drinking white wine is not resistant to the new coronavirus.

4、Hot springs, sauna and other ways to eliminate the virus has no effect.

5、Smoked vinegar has little preventive effect on the new coronavirus. And acetic acid volatilized to the room, may have a stimulating effect on the human respiratory mucosa.

6、VC does not prevent the new coronavirus, nor does it have a role in fighting the virus.

7、At present, there is no evidence-based medical evidence that anti-influenza drugs such as Abidor have a preventive effect on novel coronavirus infection.

8、At present, there are no studies that suggest that salt water has a killing effect on the new coronavirus.

9、Wearing goggles is a protective suggestion for doctors who are in direct contact with patients. Ordinary people do not need to wear goggles when they go out.

10、Chlorhexidine was not effective in inactivating the virus.

11、Smoking can prevent the virus is a rumor that has existed since the SARS period.

 

Key points of child protection for 6. parents

1、This epidemic is superimposed on the traditional flu season. Parents should rationally evaluate children's fever symptoms to avoid cross-infection caused by blind medical treatment.

2、Children should pay attention to maintaining healthy and regular habits during the holidays, do not overeat, older children are not recommended to sleep late.

3、For children under the age of 3, it is not necessarily recommended to wear masks, it is recommended to strengthen protection by reducing the number of outings.

4、The relatively small number of children may be due to the fact that parents' protective measures for children are better than those of adults, and it is also related to children's low immunity, easy colds, antibody formation and cross immunity.

5、Low susceptibility does not mean that there will be no infection. The currently diagnosed patients include two-year-old children and even 9-month-old babies. The epidemic prevention work of infants and young children cannot be relaxed.

 

7. understanding the main manifestations of the infected person symptoms

1、Manifested as fever, fatigue, dry cough. A few accompanied by nasal congestion, runny nose, diarrhea and other symptoms.

2、Some patients only showed low fever, slight fatigue, no pneumonia, more than 1 weeks after recovery.

3、Severe and critical patients may have moderate to low fever during the course of the disease, or even no significant fever.

4、When the temperature exceeds 37.3 ℃ in a calm state, it can be judged as fever.

 

How to respond 8. you develop suspected symptoms

1、If the body temperature is lower than 38 ℃, it is recommended to isolate at home, closely observe the changes of symptoms, and take ibuprofen and other drugs according to the instructions.

2、If you feel serious, go to the community hospital first.

3、If the temperature exceeds 38 ℃, go to the fever clinic.

4、There was no obvious fever, but the whole body was sore and swollen, abdominal pain and diarrhea. The patient was isolated for mild illness.

5、If there is fever accompanied by chest tightness and discomfort, you should maintain a high degree of vigilance and seek medical treatment as soon as possible.

6、I have been in contact with suspicious patients, but there is no discomfort at present. It is recommended to isolate and observe at home for 14 days, mainly to monitor the changes in body temperature.

7、Close contacts live in single rooms for home observation and refuse all visits.

 

9. release from isolation and discharge criteria

1、The body temperature returned to normal for more than 3 days, respiratory symptoms improved significantly, and two consecutive respiratory pathogenic nucleic acid tests were negative (sampling interval at least 1 day).

2、Patients with mild illness will hardly leave sequelae after cure, and will not cause secondary transmission in the short term.

 

Advice 10. Home Isolation to Maintain a Good Mentality

1、Maintain a normal life, proper rest, adequate sleep.

2、You can choose exercises that can be done at home as appropriate to reduce anxiety and maintain a good attitude.

3、Reading can relieve stress and divert attention.

4、The time to receive relevant information every day should not exceed one hour as far as possible.

5、Listening to light music, such as classical music or light music, helps to maintain emotional stability.
