Is temperature check a reliable way to detect coronavirus disease?

There is little scientific evidence to support temperature screening as a reliable method for detection of COVID-19 or other febrile illness, especially if used as the main method of testing.

Temperature readings from temperature screening systems will measure skin temperature rather than core body temperature. In either case, natural fluctuations in temperature can occur among healthy individuals. These readings are therefore an unreliable measure for detection of COVID-19 or other diseases which may cause fever. Furthermore, infected people who do not develop a fever or who do not show any symptoms would not be detected by a temperature reading and could be more likely to unknowingly spread the virus.

Can you go back to daily activities after having your COVID-19 vaccine?

Do children need parental consent for the COVID-19 vaccine?

All parents or those with parental responsibility are asked for consent and will usually make this decision, jointly with their children. The information leaflet is addressed to the child (as the recipient of the vaccine) and encourages them to discuss the decision about the vaccine with their parents.
In secondary schools, some older children may be sufficiently mature to provide their own consent. This sometimes occurs if a parent has not returned a consent form but the child still wishes to have the vaccine on the day of the session. Every effort will be made to contact the parent to seek their verbal consent. The school has no role in this process.
