Lowest mortality rate despite the rise of U.S. omicron strains… thanks to increased immunity


The death rate of patients with severe cases was one-quarter of that of last year… “It seems difficult to fall further”
Expert “Fear of a resurgence of deaths in winter when immunity is low”

Although the COVID-19 sub-mutant virus of COVID-19 in the United States is rampant, the overall immunity of society has risen, and the death rate from COVID-19 is at the lowest level since the pandemic.

According to the New York Times (NYT) on the 20th (local time), the death rate from COVID-19 in the United States is the lowest since the pandemic began in early 2020.

Some institutions estimate that the death rate of patients with severe COVID-19 was one-third lower than last summer and a quarter lower than in December of the same year.

The average daily death toll from COVID-19 in the U.S. is 314, which is one-tenth of what it was in January last year.

The number of confirmed COVID-19 cases in the United States, including asymptomatic and mild cases, has increased tenfold compared to January last year, suggesting a significant decrease in the number of deaths compared to those infected.

Experts analyzed that the decrease in the number of deaths was not due to a weakening of the risk of the COVID-19 virus, but to an increase in immunity in society as a whole.

It is said that a significant number of people across the United States experienced the infection, with about 200,000 people dying from COVID-19 due to the omicron mutation epidemic last winter.

“The combination of natural infection and vaccination has made communities stronger than ever,” said Joe Gerald, a public health researcher at the University of Arizona. January to early March
I was infected with Omicron.”

Meghan Lani, a professor of emergency medicine at Brown University, said: “Overall, people with COVID-19 today are much less sick than those infected last winter. It looks like a disease,” he said.

However, the proportion of the elderly among the corona deaths has increased compared to last year, and the death rate of those who are not vaccinated is still much higher than that of those who are vaccinated.

If immunity is weakened and new mutations that evade the existing immune system are prevalent, the elderly, etc. may become infected with Corona 19 and fall into serious condition.

“The longer the time after vaccination, the less effective the immune response will be,” said Abra Karan, a professor at Stanford University who specializes in infectious diseases.

The NYT reported that the high-risk group of the elderly, diseased, or weakened vaccine immunity is at risk as the Omicron sub-mutation, which has become more contagious since the spring, has spread, but the government’s vaccine booster shot (boost) policy is stagnant. It is expected that the death toll will not decrease further here.

The New York Times also pointed out that regional differences in access to booster shots and edible drugs for COVID-19 are also a problem.

The booster shot vaccination rates for blacks and Hispanics are lower than for whites, and patients who do not have primary care doctors or live far from pharmacies may have difficulties in prescribing medications.
