AZ vaccine/side effects and protection
The AZ vaccine was jointly developed by the University of Oxford and AstraZeneca. It has been authorized for use by other advanced countries such as WHO, the European Union, and my country. The AZ vaccine is a non-replicating vaccine containing the SARS-CoV-2 virus spike protein gene. type adenovirus vector vaccine. Victims need to be vaccinated in 2 doses, and the interval between vaccinations is recommended to be more than 8 weeks.

The storage condition of the vaccine is 2-8°C, and the protective power is 70%, which seems to be lower than that of Pfizer vaccine (95%) and Moderna vaccine (94.5%). Shi Xinru mentioned that the clinical trial sites of different brands of vaccines are different, and the infection status of epidemic areas or non-epidemic areas is also different, which may affect the data. As long as it can pass the clinical test and obtain approval, it is a useful vaccine.

The incidence of complications (serious allergic reactions) of the AZ vaccine is about 15.2 per million. A small number of victims may even develop thrombotic thrombocytopenia purpura, which may cause symptoms such as dyspnea, chest pain, and fever. In severe cases, complications may occur. Arrhythmia and myocardial damage.

Minor side effects after vaccination include redness, swelling and pain at the injection site, headache, muscle pain, fever, fatigue, chills, and nausea. In particular, the older you are, the fewer side effects of the AZ vaccine. Luo Yijun, deputy head of the medical response team of the command center, said that young people have a stronger immune system, and the immune response is more severe after vaccination. Most of the side effects are temporary and will resolve on their own after a period of time.

Modena Vaccine / Side Effects and Protection
The Moderna vaccine is an mRNA vaccine developed by Moderna Pharmaceuticals in the United States. mRNA can produce proteins that trigger immune responses and produce antibodies to resist new coronary pneumonia. The storage conditions of the vaccine are -20°C. The shelf life at ~8°C is 30 days. Victims need to receive 2 doses at least 28 days apart.

The protection of the Moderna vaccine is 94%. The side effects after vaccination include pain at the injection site, headache, muscle pain, joint pain, fatigue, chills and fever. According to statistics, the proportion of side effects of the Moderna vaccine is slightly higher than AZ vaccine, but there have been no cases of thrombosis.

High-end vaccine, Lianya vaccine/side effects and protection
For domestic vaccines, Lianya vaccine and high-end vaccines are recombinant protein vaccines. The virus spine protein is produced by gene recombination, and the vaccine is made into the immune system to generate an immune response. The storage temperature is 2-8°C, and the protective power It is not yet clear that the second-phase trials of the two domestic vaccines have entered the final stage, and the test data can be released around June.

BNT Pfizer Vaccine / Side Effects and Protection
The BNT Pfizer vaccine is an mRNA vaccine jointly developed by the United States and Germany. It has been urgently authorized for use by advanced countries such as the World Health Organization and the European Union. The Pfizer vaccine needs to be stored in ultra-low temperature freezing at -60 to -80°C, and the storage time under refrigeration temperature It was revised in mid-May this year, from the original 5 days to 1 month, and the victim needs to be vaccinated with 2 doses, with an interval of at least 28 days.

The Pfizer vaccine has a protective power of up to 95%. The side effects include redness, swelling and pain at the injection site, headache, muscle pain, joint pain, rash, and fever. The probability of severe allergic reaction is 18.8 per million.

Johnson & Johnson Vaccines / Side Effects and Protection
The Johnson & Johnson vaccine was developed by Johnson & Johnson. It belongs to the same adenovirus vector vaccine as the AZ vaccine. The storage temperature is 2-8°C, and the protective power is 66.3%. The characteristic of the Johnson & Johnson vaccine is that only 1 injection is required The side effects are similar to other vaccines, but the symptoms are milder, but there are very few cases of serious complications such as blood clots and blood clotting disorders.

The new crown epidemic has entered its fourth year, and the number of recovered patients and repeated infections has increased over time. The subtype strains BA.1 and BA.2 of the latest virus variant Omicron have successively dominated the global epidemic and are more contagious, but in vaccines Under the influence of several factors such as the general enhancement of natural immunity, the follow-up of drugs and therapy, the severe and fatality rates have been significantly reduced.

At the same time, more attention has turned to long-term symptoms of Covid-19, or “long Covid-19,” including adults and minors.

The new coronavirus only emerged at the end of 2019, and the global pandemic began in early 2020. Therefore, long-term data studies are lacking, and the existing definitions can only be based on small-scale samples and short follow-up observations.

Whether the long-term symptoms of the new crown will disappear, whether the patient will recover, and how long the sequelae can last, these questions are still unanswered. The Lancet, an authoritative world medical journal, said in an article in August 2021 that long-term symptoms of the new crown are the number one challenge of modern medicine.

What are the long-term symptoms of the new crown?
The WHO said in an official statement that the long-term symptoms of the new crown are the sequelae of the new crown. According to the clinical definition published by the World Health Organization in October 2021, this symptom usually occurs in people who have been diagnosed with or may be infected with the new coronavirus, and usually “appear within 3 months of infection, persist for at least 2 months, and cannot be explained by other diagnoses”.

There is currently no uniform standard for the “long-term” time span. A UK study says it will follow up for 25 years. It has only been more than two years since the initial discovery of the new coronavirus, which requires a longer period of observation and the accumulation of relevant data.

According to British medical staff guidelines, symptoms that last for more than 12 weeks and cannot be explained by other reasons should be classified as “long new crown”. These symptoms may include:

extremely tired
shortness of breath, chest pain, or tightness
Memory and concentration problems (“brain fog”)
Changes in taste and smell
joint pain
Symptoms, severity, and medical history vary from person to person. The most common symptom by far is severe fatigue.

Other symptoms include: muscle pain, hearing and vision problems, headaches, loss of taste and smell, and damage to the heart, lungs, kidneys, and intestines, diarrhea, and mental health problems including depression, anxiety, and distracted thinking.

Therefore, NINGBO CHANGQI （DoctorClean®) reminds everyone not to relax completely because the current epidemic situation has improved. Wear masks, wash your hands frequently, and maintain social distance. You still need to pay attention.

It has been more than a year since people got into the habit of slathering hand sanitizer on their hands and personal items any time they get the chance. Of course, it is better to over-sanitize than under-sanitize, but there is more to it. Hence, it is essential to raise awareness about effective hand sanitizer use. So, let’s delve into the most common mistakes.

1. Not using the right hand sanitizer

It is not unimportant which hand sanitizer you use or provide for use as an employer. This is especially important because most people believe that sanitation with alcohol-based sanitizers is enough to protect themselves from germs in their surroundings.

However, if the sanitizing liquid does not have at least 60 percent of ethyl alcohol or 70% of isopropyl alcohol, then it does not provide the necessary protection from COVID-19 and other tactile-propagated viruses. Mild sanitizers are enough to kill bacteria, but not dangerous viruses such as SARS-CoV-2.

2. Not storing the liquid at the right temperature

A related issue involves people not keeping their hand sanitizer dispensers at the right temperature. Prolonged periods in the sun reduce the potency of the sanitizing liquid. This means that you need to place your bottles away from direct sunlight. Therefore, keeping your sanitizer in your car might make your sanitizing liquid less protective.

3. Using inadequate hand wipes

One of the most common hand sanitizer mistakes to avoid is the belief that baby wipes and hand wipes can be used for sanitation. This is true only if they contain antimicrobial substances, such as alcohol. Therefore, it is crucial to check if the product you are using can disinfect.

Most people are aware that it is important to use hand sanitizers in the office and other public spaces. However, if they use ineffective sanitizers, they might unwittingly spread or contract viruses under the conviction their hands are clean when in reality they are not.

4. Not sanitizing the hand sanitizer dispenser

Here is a legitimate paradox related to hand sanitation. Namely, in order to apply the sanitation liquid, you have to touch the bottle or the lever of the manual hand sanitizer dispenser. This means that you are unnecessarily exposing yourself to possibly contaminated surfaces.

So, you hand someone your bottle containing hand sanitizer. The person disinfects the hands, but not the bottle that contains the disinfectant. In this way, your bottle is potentially carrying the virus just because we perceive that the bottle must be clean since a cleaning liquid is inside it. Hence, make sure that you sanitize the bottle as frequently as you sanitize your hands. 

5. Not having the right dispenser

Likewise, it could be the case that a few dozens of people in an office building touch the same sanitizer dispenser in a single hour. Most companies have turned to automatic hand sanitizer dispensers instead of manual ones to avoid unnecessary mass contact. In this way, the number of people directly touching the dispenser is brought to a minimum.

This is a crucial step in stopping the spread of COVID-19 now that so many companies are going back to offices. Hence, if you plan to move your company to a new office building, make your new space a germ-free zone by installing automatic hand sanitizer dispensers. This should help keep the level of protection of your employees and customers under control. Also, it is very important that your new office space is thoroughly disinfected before you bring in the necessary office supplies and actually move in.

6. Not using sanitizer for an adequate amount of time

The usual advice states you should wash your hands for at least 20 seconds, that is, the amount of time it takes to sing the Happy Birthday song twice. However, people rarely do so when they are disinfecting their hands with hand sanitation liquids. The reason why this might happen could be due to the fact people associate alcohol with instant sanitation.

However, you should also take 20 to 30 seconds when you use sanitation liquid. So, a hard and fast rule is to rub until your skin soaks up the liquid.

7. Not applying enough sanitation liquid

Surprisingly enough, sometimes people do not put enough sanitation liquid to adequately disinfect. The perfect amount of sanitation liquid should be the size of a quarter or a nickel. 

However, this is impossible to determine if the sanitation liquid is sprayed from a pump or a sanitation liquid dispenser. Most of them are built to let out the right amount when you do a full push down on the pump or the lever. As for automatic hand sanitizers you see in offices and retail stores, they let out just the right amount of sanitation liquid.

8. Not rubbing your hands properly

Even though proper handwashing has been in the public spotlight since the start of the pandemic, sometimes it happens that people fall into a routine that they think is effective but is actually not.

Unfortunately enough, even a microscopic area left unwashed can attach particles of the virus. This means that you need to scrub the front and the back and in between fingers. You may even want to scratch your palms while spreading the liquid to disinfect under the nails.

We hope you have found helpful information in this short article about frequent hand sanitizer mistakes to avoid! All in all, just keep calm and disinfect the viruses away!

1. The virus is mainly transmitted through droplets such as sneezing and coughing, and the infection is caused by direct or indirect contact with the mucous membranes such as the mouth, nose and eyes.

2. Contact with virus-contaminated items can also be infected through the above routes.

3. In certain places, such as densely crowded and closed or poorly ventilated rooms, it may also spread through aerosols, which requires caution.

Everyone, please pay attention to the second one. Contact with articles contaminated by viruses can also be infected through the above-mentioned channels.

When everyone touches public items contaminated with respiratory secretions, such as elevator handrails, elevator buttons and door handles, in public places, and then touches the oral cavity, nasal cavity, eyes, and other mucous membranes, they are easily infected with the virus.

When should I wash my hands?

When going home
After touching public goods (such as touching elevator buttons);
After sneezing or blowing your nose;
Before and after touching the mouth, nose, and eyes;
Before and after meals.
How to wash my hands properly?

The general specific hand washing and kneading steps are:

① Palms are opposite, fingers are close together, rubbing each other;

② Rub the palms of your hands along the back of your fingers and exchange with your left and right hands;

③ The palms are facing each other, and the hands are rubbed against each other with fingers crossed;

④ Hold the thumb of the left hand in the right hand to rotate and rub, and exchange the left and right hands;

⑤ Bend your fingers so that the joint rotates and rubs in the palm of the other hand, swapping left and right hands;

⑥ Put the tips of five fingers together on the palm of the other hand to rotate and knead. Wash your wrists if necessary.

Washing hands with running water when going out is not convenient, and when there are no visible pollutants on the hands, you can use alcohol-based quick-drying hand disinfectants to disinfect your hands.

Do you know the difference of cold and flu? Here’s the comparation graphics for you, it would be helpful to tell the difference:

cold, flu, difference

Other Clues

You can get a cold anytime — spring, summer, or fall, but most likely in winter.

Flu season typically runs from November through March, although you can get it in October or as late as May. You can catch the flu at other times of the year. But symptoms outside of flu season are more likely to be from a cold or an allergy.

Flu tends to be much worse than a cold. And the flu, especially in children and older people, is more likely to lead to serious health problems such as pneumonia and a hospital stay.

Rarely, symptoms may not be enough for your doctor to know if it’s a cold or the flu. Then she may do a test to find out what you have.

80% of all infections are transmitted through the hands. Washing your hands can prevent the transmission of respiratory viruses, influenza virus, enterovirus and respiratory syncytial virus, among others, as well as gastroenteritis, hepatitis and other more serious diseases. Infections are very common in long-term care centers and represent an important cause of contagion and mortality among residents of geriatric centers.

A study published recently in the American Journal of Infection Control evaluated the impact of implementing a specific program of preventive actions with hand hygiene in nursing homes.

During the implementation of the program, health professionals took measures related to the hygiene of the hands, provided greater access to disinfecting hands through pocket bottles and new dispensers, as well as installing information screens and training programs.

The researchers evaluated the hand hygiene practices measuring the consumption of hand sanitizers and evaluating the rate of incidence of acute respiratory infections and acute gastroenteritis.

Conclusions of the study:

There was an increase in the use of hand sanitizer by health personnel during the one-year study period.

The mortality rate was significantly reduced: from 2.10 per 100 residents per month, compared to 2.65 per 100 residents per month in the control group.

Healthcare personnel also experienced lower prescriptions of antibiotics at 5 daily doses defined for 100 days resident versus the daily defined doses of 5.8 of the control group for 100 resident days.

Hospitalizations did not make a  difference between the two groups.

What does it mean?

Keeping your hands clean is one of the most important steps to avoid getting sick and spreading germs to others. When a center implements a hand hygiene program increases the consumption of disinfectants, and in return achieves a more protected space for residents and workers, reduces costs in antibiotic treatments, avoids labor losses and improves the quality of the service.
If you plan to implement improvements with regard to accessing the hand sanitizer to your business,  we advise you to choose the best options offered by the market in disinfectants with sanitary registration and dispensers.

Question 1: How to disinfect?

1. Disinfection of vomit and feces

The vomit is completely covered with a chlorinated disinfectant containing 5000mg/L~10000mg/L with gauze, etc., and carefully removed. Contaminants in toilets or containers can be carefully poured into a sufficient amount of chlorinated disinfectant from 5000 mg / L to 10000 mg / L for more than 30 minutes and discharged into a sewage treatment system with a disinfection device.

2. Surface, wall and other surface disinfection

Surfaces of objects that are frequently in contact (such as door handles, desks and chairs, dining tables, crib railings, stair handles, toys, etc.) are soaked, sprayed or wiped with a disinfectant containing 1000 mg/L of effective chlorine. After 30 minutes, wipe with water. .

3. Disinfection of clothing, bedding and other fabrics

The solid soil was removed and immersed in a chlorine-containing disinfectant solution having an effective chlorine content of 500 mg/L for 30 minutes, followed by washing. If not disinfected immediately, they should be placed in a sealed bag and disposed of as soon as possible.

4. Disinfection of food and beverage appliances

After the meal (drinking) and food processing tools remove the food residue, boil and disinfect for 30 minutes, or use the effective chlorine to soak or wipe the 500mg/L chlorine disinfectant. After 30min, wash it with water.

5. Disinfection of drinking water and water supply facilities

Contaminated water and water should be stopped immediately. Thoroughly clean and disinfect the polluted water supply pipe network, water tank, bottled water machine and straight drinking fountain. Soak it with 100mg/L disinfectant solution for 1 hour and rinse the pipe network.

6. Indoor air disinfection

Keep indoor air circulation. Natural ventilation or mechanical ventilation can be adopted, and the unmanned space can also be disinfected by ultraviolet rays. The indoor air can not be disinfected by spraying disinfectant.

Question 2: How to wash your hands effectively?

Disease control experts reminded that it is the key to prevent Norovirus infection and wash hands frequently. Washing hands is one of the most effective ways to stay away from germs and prevent cross-contamination in daily life.

1. When should I focus on washing my hands?

Wash out your hands from the hospital, before, after, after going home, after touching garbage and animals, after sneezing or coughing, and after touching coins.
