The Indian variant of the COVID-19 variant virus (Delta) is raging in many countries. In addition to the spreading power of Delta is 40-60% higher than that of the British variant (Alpha), it seems to be smarter. The symptoms after infection are like a cold, the symptoms are mild, but it can breathe out more viruses.
The symptoms of the original virus of COVID-19 and the British variant are mostly systemic, but the Indian variant has changed. It can cause local cold-like symptoms, which can cause people to lose their vigilance while carrying a large amount of virus and spreading it out.
Related scholars pointed out, “The pathogenic mechanism has changed and the virus has become smarter. It is quietly latent and difficult to detect.” In the original strain and the British variant, apart from a certain percentage of asymptomatic infections, the rest mostly have respiratory symptoms. “Systemic symptoms” such as fatigue, fever, and muscle aches are the main ones; the Indian variant is different. It often causes local cold symptoms (such as runny nose, sore throat, and mild headache).
“Runny nose”, “headache”, and “sore throat” are the three common symptoms of Delta infection. It is like a cold, and it is easy to be ignored. The abnormal smell and taste that often occurred in the past with the new coronavirus does not appear in this strain. This means that the system that Delta violated is different.
Sometimes you will inevitably sneeze after a runny nose, and the virus will be released in large quantities at once. When the amount of Delta virus in the body is high, the head may be painful. Therefore, the definition of the past notification has to be changed. I want to find the most effective infection for the infected person. The way is screening.
Some Delta cases with a Ct value of only 10 or 11 show that a very high amount of virus can be detected after infection with Delta. The infected person seems to have mild symptoms, but they can still carry a large amount of the virus, and the time to discharge the virus will be prolonged. Therefore, the British epidemic prevention system is very troublesome for Delta. The above-mentioned characteristics allow it to spread quickly in the community.
Faced with the “post-transformation” Delta, if Delta travels further into the community, the amount of virus exhaled by the infected will greatly increase. During this time, everyone is not encouraged to gather together, because Delta is easier to infect in confined spaces than other mutants. Households are also reminded to strengthen indoor air circulation, and windows must be opened in any clustered places to reduce aerosol (microvirus particles) infection.
