Threatening "Delta", experts tell you this prevention is the most effective!!

At present, Delta has become the most important viral strain in the global epidemic, which has also caused local epidemics in Guangzhou, Shenzhen, Dongguan and other places.What is its "power" in?How can we prevent this?Small make up this take you to interpret!

1.Delta

What kind of tough guy is he？

Feng Zijian, a researcher at the China

Center for Disease Control and Prevention,

summed up three salient features

of the Delta strain, namely:

It's more contagious

High viral load

There may be immune escape,

but the vaccine still provides protection

Characteristic one, the transmission force is stronger

"Delta" mutation strain virus infectivity
And the ability to transmit has been significantly enhanced
The incubation period or passage interval is shortened
The spread of the virus is accelerating
Existing research data show that
The Delta strain is by far the most transmissible of the variants
Twice as fast as previous strains
More than 40 percent more transmissible than the strain found in the United Kingdom

Characteristics 2. High viral load

PCR based on samples from people infected with Delta virus
Virus detection results show
The viral load is characterized by a significant increase
After the onset of the disease, the patient became severe,
The proportion of severe cases is higher than before
And the time to convert to the severe, critical type also moved forward
The patient had a high viral load
The time required for the patient's nucleic acid to turn negative is prolonged
A team of British researchers found that
Compared to people infected with the mutant alpha strain
People infected with the Delta variant were twice as likely to be hospitalized

Characteristics three, there may be immune escape,
But the vaccine still provides protection

People who had not been vaccinated among the confirmed cases
The proportion of patients who become or develop severe disease
Significantly higher than those who had been vaccinated
The vaccine remained protective against the new strain
Other studies have shown that compared to unvaccinated cases
Cases of vaccination
The time from diagnosis to antibody positive is short
High CT value (low viral load) and short hospital stay

2. prevention and control measure

Experts tell you this is the most effective way to prevent it

Through the interpretation of the characteristics of Delta, let us understand the importance of prevention and control measures, then home disinfection should pay attention to what aspects?What aspects should be paid attention to in the cleaning and disinfection of public places?How to do scientific disinfection?Xu Yan, deputy Secretary of the Party Committee and deputy Director of jiangsu Provincial Center for Disease Control and Prevention, chief physician, was interviewed by the journalists of Jiangsu Media Media News Center and answered questions for everyone.

What should be paid attention to in the cleaning and disinfection of public places？

In common public places where there have been no confirmed cases or asymptomatic infected persons, ventilation and cleaning should be given priority to, supplemented by preventive disinfection, and dust-free wet cleaning should be performed every day.

For the surface of objects frequently contacted by the public, such as doorknobs, doorbell buttons, elevator buttons, public electronic equipment and keyboards, public seats and armrests, etc., after cleaning, key disinfection should be carried out.At the same time, the frequency of cleaning and disinfection can be increased depending on the flow of people.

In the cleaning process, the cloth should be washed and changed frequently, and often exposed to the sun or put in a cool and ventilated place to dry.Or regular use of 500mg/L effective chlorine disinfectant soaking disinfection, 30 minutes after rinse with water.

How to do scientific disinfection？

Scientific disinfection follows the principle of "five important" and "seven no".

The "five wants" refer to:

The isolation ward and the patient's residence shall be disinfected at any time and terminally;
The surface of environmental objects in crowded places such as hospitals, airports and stations should be increased for disinfection;
High frequency contact doorknobs, elevator buttons, etc., to strengthen cleaning and disinfection;
Garbage, feces and sewage should be collected and treated innocently.
Do good hand hygiene.

"Seven no" refers to:

No large-scale disinfection of the outdoor environment;
Do not disinfect the air of the external environment;
Do not disinfect personnel directly with disinfectants;
Do not disinfect ponds, reservoirs, artificial lakes and other environments by adding disinfectants;
Do not disinfect the air with chemical disinfectants under human conditions;
Wipe and spray the environment without glutaraldehyde;
Do not use a high concentration of chlorine-containing disinfectant for preventive disinfection.

Learn to disinfect
Scientific virus prevention!
Vaccines are currently used to prevent infectious diseases
The most effective way,
Everyone should go to vaccinate as soon as possible
