Alert! Another Covid-19 mutant virus appears, or it may trigger a new epidemic peak! Delta strain making a comeback? The latest study: severe illness or lower IQ

At present, the covid-19 epidemic is still one of the focuses of the market.

The shadow of the delta mutant strain reappeared. On May 4, according to CCTV news, an Israeli research team found that while the Mikron strain accelerated the spread, the delta strain was still “secretly spreading”, the researchers warned The delta strain may “make a comeback,” he said. About this topic once rushed to Weibo hot search.

Judging from the global epidemic situation, the fastest-spreading and most difficult-to-prevent is still the mutant strain of Omicron. The fastest-spreading Omicron BA.2.12.1 once again triggered a counter-attack in the United States. According to the latest data from the US Centers for Disease Control and Prevention (CDC), the growth rate of BA.2.12.1 was 23% faster than that of BA.2 to 27%.

At present, the continuous mutation of the SARS-CoV-2 coronavirus may be the biggest uncertain risk. On May 2, local time, South African medical experts warned that the newly discovered new variants BA.4 and BA.5 of the Omicron mutant strain are likely to be able to evade vaccines and natural immunity, and the transmission may be higher and extremely It is possible to trigger a new wave of epidemic peaks.

In the context of the continuous and repeated global epidemic, the SARS-CoV-2 drug has become one of the most popular tracks. On May 3, local time, in the latest financial report disclosed by Pfizer, an American pharmaceutical giant, the SARS-CoV-2 oral drug Paxlovid became the focus of the market, with sales in the first quarter reaching 1.5 billion US dollars (approximately RMB 10 billion). Pfizer expects Paxlovid’s sales to reach $22 billion (about 145.4 billion yuan) in 2022.

Delta strain or comeback?

On May 4th, a topic about #delta virus strains may make a comeback# sparked heated discussions, and once rushed to the hot search, the topic was read more than 200 million, and the discussion volume also exceeded 11,000.

The topic of the Delta strain suddenly attracted attention, which was related to a CCTV report.

On May 4, according to CCTV news, the Ben-Gurion University of the Negev in Israel issued a communiqué saying that the research team found that while the mutated new coronavirus-virus Omicron strain accelerated the spread, the delta strain was still “Clandestine Propagation”. The researchers warned that the delta strain could make a “comeback.”

Researchers monitored wastewater in the southern Israeli city of Beersheba between December last year and January this year and found that the delta strain did not disappear as the Omicron strain accelerated. In “Clandestine Propagation”.

The prediction model developed by the research team shows that the transmission of the Omicron strain will “taper or even disappear” in the next few months, but the delta strain will continue to spread, which may lead to a new wave of delta. Strain infections or new threatening mutant strains emerge.

According to public information, the delta mutant strain was first discovered in India in October 2020 and is one of the driving factors of the second wave of the epidemic in India. In 2021, the delta mutant strain once became one of the most popular strains in the world. It has spread to at least 185 countries and regions. Relevant studies have found that the delta variant has the characteristics of short incubation period, fast transmission speed, high viral load, long time for nucleic acid to turn negative, and it is more likely to develop into critical illness.

As of now, the World Health Organization still classifies the delta and Omicron variant strains as “spreading strains of concern”.
