The Nevada State Public Health Laboratory has identified a rare case of COVID-19 reinfection occurring just 22 days after the patient first tested positive.
The patient, an unvaccinated 31-year-old Mineral County man with no underlying health conditions, first tested positive for the delta variant and then, three weeks later, for a different strain that evolved from the delta variant, Mark Pandori, director of the lab at the University of Nevada, Reno’s School of Medicine, told the Review-Journal this week.
Infection from COVID-19 typically results in immunity from reinfection for a minimum of several months, according to the Centers for Disease Control and Prevention. Such rapid reinfection, especially in a young and healthy individual, could mean that the virus has mutated to a degree that makes it more resistant than previously seen to the protection afforded by past infection or from vaccination.
More such reinfections would first need to be identified to know if this is the case.
“We don’t know how widespread the phenomenon is right now, but it implies that the virus is definitely going to be fine in terms of staying in circulation in the population,” given how much the strain that caused the reinfection differs from the delta variant, he said.
The strain, a sublineage of delta known as AY.26, has 31 genetic differences from delta, including on the spike protein, the part of the virus targeted by vaccines, he said. It is this genetic variety that especially concerns him.
“My concern is that there’s a scientific rationale for this being indicative of a bigger problem,” said Pandori, whose lab in August 2020 reported the first known case of COVID-19 reinfection in North America.
That bigger problem is the possibility of increasing numbers of reinfections as well as so-called breakthrough cases in vaccinated individuals.

自然免疫产生的新的免疫力更接近delta，都没有扛住AY.26，22天再感染
疫苗的抗体是武汉出现的原始病毒，遇到AY.26，后果更糟了
Scary if it is widespread and not just a single case
AY26 在哪第一次发现的？
看来，专杀打过疫苗的病毒变种，终于来了。

数据库显示的出现时间可能不准，就像AY25，显示第一次出现是2020年7月，这时候
delta都没出现，怎么子变种会先有了？
AY26 也去年就有了。但是在印度没发起来不是吗？

数据库自动显示的时间可能不对，可能是匹配几个特征就认为是AY26了
delta子变种是按照出现时间命名的，AY1是delta+
现在到AY38，AY26是很晚才被命名的
