Characteristics and protection of delta strain

At present, the novel coronavirus pneumonia is still in the pandemic

.

The incidence of epidemics has been increasing in many countries

.

Recently, the local imported cluster caused by overseas imports has spread to many provinces

.

What are the new characteristics of the delta strains that are currently transmitted by the delta strain? Based on the current research, delta virus strain shows the following obvious characteristics: 1

.

Fast transmission speed, 2

.

Strong infectivity and nearly 100% increase in transmission rate, 3

.

Short incubation period, 4

.

High virus load, 5

.

Long treatment time and easy to develop into severe disease, 6

.

What is the mode of transmission of delta virus strain with “immune escape”? 1

.

Respiratory droplet transmission

.

The droplets from the respiratory tract sprayed by sneezing, coughing and even speaking carry viruses, which reach other people’s respiratory tract, mouth, eye and nose mucous membrane through dispersion and inhalation, resulting in infection

.

This is the most important mode of transmission, so keep interpersonal distance

.

2

.

Transmission of pollutants

.

Respiratory droplets and secretions with virus pollute the surface of the object, and the virus can survive for a period of time

.

When others touch the contaminated surface with their hands, they will be infected when they touch their mouth, eyes and nose

.

That is why we emphasize the importance of hand hygiene

.

3

.

Air transmission, or aerosol transmission

.

Especially indoors, in the narrow space with poor ventilation, if an infected person coughs and sneezes during detoxification, in addition to large particles of respiratory droplets, very small particles of respiratory secretions will be formed, which can hover in the air

.

If others inhale, they can cause infection, and even those who excrete viruses will leave the space, There will still be viruses in the air for a certain period of time, and others will also cause infection after entering

.

How to strengthen protection against delta strain? 1

.

Wear masks correctly

.

Whether it is to protect individuals from infection or infected people to protect others from infection, wearing masks is very important, which has been internationally recognized as an important preventive measure

.

The habit of carrying masks should be formed, especially when going to public places, especially when entering closed spaces such as public transport and elevators

.

2

.

Keep a safe social distance

.

Try to avoid crowd gathering, and keep more than 1m away from others in public places

.

3

.

Pay attention to good personal hygiene

.

Hand hygiene is particularly important

.

Wash your hands frequently

.

Wash your hands with soap or hand sanitizer and running water

.

After going out and returning home, wash hands in time with hand sanitizer or soap and flowing water according to the “seven step washing method”

.

If necessary, disinfect with disinfectant wipes or wash free disinfectant to avoid touching the mouth, eyes and nose with unclean hands

.

4

.

Maintain good indoor ventilation

.

Keep good ventilation at home and office

.

Open windows for ventilation no less than two to three times a day, no less than 30 minutes each time

.

5

.

In case of respiratory symptoms such as fever, dry cough and sore throat, seek medical attention in time

.

In the process of medical treatment, report your experience of contacting high-risk personnel and traveling to high-risk areas to the doctor, and remind the doctor

.

6

.

Keep a good attitude

.

Scientifically understand the changes of the epidemic situation, obtain information related to the epidemic situation through official channels, and do not believe or spread rumors

.

7

.

Make a travel plan before traveling

.

Understand the risk status of the travel destination in advance, arrange their own travel activities, and travel as little as possible

.

Due to the increased infectivity of the novel coronavirus delta variant strain, our personal preventive measures should be more strict and implemented more seriously, so as to protect ourselves and others
