Long-term COVID risk worse after delta than omicron, data shows


The risk of lingering symptoms after COVID-19 appears influenced by the strain of coronavirus that caused the infection, according to analysis from the UK, where around 1.8 million people said they had suffered long COVID in early April.

The odds of reporting fatigue, shortness of breath, difficulty concentrating and other persistent symptoms were 50% lower following infections likely caused by the omicron BA.1 variant than those likely caused by the delta strain, the Office for National Statistics said in a report on Friday. . The difference was only found in adults who had been double-vaccinated when infected. Among those who were triply vaccinated, the difference was not statistically significant.

Among triple-vaccinated adults, the odds of reporting long COVID were higher after infection with the omicron BA.2 variant than the BA.1 variant, the analysis found.

More than two-thirds of people with self-reported long COVID, or 1.2 million people, said their symptoms negatively affected their daily activities, and nearly a fifth said their symptoms limited them a lot, according to the office of the statistics.

Most long-lasting COVID symptoms don’t appear to be life-threatening, but things like shortness of breath or fatigue can be debilitating. The U.S. Government Accountability Office said in a March report that the long COVID could affect the broader economy due to decreased work participation and increased need for computer use. disability insurance from social security or other state-subsidized insurance.
