Almost half of the 25- to 34-year-olds said in a survey that they would break the rules if the corona virus were blocked a second time.
The survey found that one in five thinks they have had Covid-19 even though they have not had a positive test.
Two-thirds of respondents to the nationwide survey said that a second ban will take place in Britain.
The 25-34 year olds were most likely to say they would ignore the official guidelines in this case. 47% admitted that they would break the rules.
39% of 18- to 24-year-olds said they did not follow the blocking measures exactly, while only 23% of 65-year-olds and above gave the same answer.
The July 2020 survey of 2,000 adults found NHS swab tests to be the most trustworthy for Covid-19, but 44% of respondents said they were unsure of their effectiveness.
Private antibody tests with quick results were the least trustworthy of all test options.
Dr. Sam Rogers, medical director of Medichecks, a health care blood company that commissioned the study, said it shows that people are “confused.”
“It is worrying that people are drawing their own conclusions as to whether they have the virus and are acting accordingly,” said Dr. Rogers.
Of the thousands of Covid-19 antibody tests the company has done, 85% have had negative results.
Dr. Rogers said “many people” believed they had been exposed to the virus but had no detectable antibodies.
The survey found that only 8% of respondents believed that coronavirus offered complete immunity.
However, 60% of respondents said that people are less likely to get the virus again or infect others.
“If people are not sure, but suspect they have had Covid-19, there is a risk that they will behave differently,” said Dr. Rogers.
“This could be manifested by not washing your hands regularly and not following the guidelines for social distance. These are measures that risk a second climax and ultimately cost lives.”
Only 8% of those questioned had confirmed Covid-19 with a positive test.
