Where did Delta come from? Is my protection still effective?

Feature 1: The most popular strain in the world

2. Highly contagious

The transmission was completed in 14 seconds in the same environment and without physical contact.

3. Short incubation period

The disease can develop in as little as 24 hours.

It can be passed down five or six generations within 10 days.

4. High viral load

The gas exhaled by the patient is highly toxic.

5. Atypical symptoms

Some patients only show fatigue, olfactory impairment, and mild muscle aches in the early stages.

6. Long treatment time

Patients are prone to develop severe illness.

7. Possible “immune escape”

The Delta strain can partially evade neutralizing antibodies to suppress the immune response.

As of 15:00 on August 8, there are 3,498 confirmed cases, 555 asymptomatic infections, 4 suspected cases, and 44 severe cases in my country.

Was the previous protection effective?

It works! Specific steps:

1. Avoid crowding: Do not move unless necessary. There is a risk that the Nanjing epidemic will continue to spread to other areas in the short term.

2. Wash your hands frequently and wear a mask. Although the virus's ability to spread has significantly increased, the way it spreads has not changed. Change your mask every 1 to 2 hours in summer, wash your hands and keep a good distance of one meter.

3. Vaccines are still effective, so get vaccinated actively. Most of the confirmed cases in this round of epidemic in Nanjing have been vaccinated. For these vaccinated cases, the overall symptoms are mild and the course of the disease is short, indicating that vaccination still has a protective effect.
