In one example, the CDCs guidance didn't recommend that schools conduct daily symptom screening for all K-12 students because some people with COVID-19 are asymptomatic. The report also found key inconsistencies in Centers for Disease Control and Prevention guidance for schools, such as how to screen for the virus and when schools should close down if students or teachers start testing positive for the virus. Such was the "inconsistent" guidance the CDC has given to schools, according to the GAO report. Some guidance said a single case shouldn't lead to a shut down; other guidance suggested closing down the school for two to five days. The CDC, in response, said it strives to ensure that all content is consistent and up to date.
