The Ministerial Advisory Committee (MAK) on Covid-19 again discouraged the use of disinfection tunnels at schools because it posed health hazards.
This comes after several schools made use of such tunnels on Monday to irrigate pupils and teachers at the school entrances with chemicals.
Prof. Salem Abdool-Karim, chairman of the MAK, who serves the government for medical advice on the virus disease, said on Wednesday that there was no evidence that these disinfection tunnels were effective against the spread of Covid-19.
“By showing that chemicals kill the coronavirus on surfaces or animals, this is not proof that it will prevent Covid-19 in humans,” says Abdool-Karim.
He says the chemicals used could even increase the chances of pupils and teachers getting Covid-19.
“When the spray reaches sensitive parts of the mouth, nose and eyes, it is often toxic, which can damage the protective layer of the mouth and throat, which can increase the susceptibility to Covid-19.
“Because the coronavirus does not invade people’s skin, there is no reason to irrigate the skin or clothing. Spraying chemicals on people can change the protective layer of the skin that protects us from skin diseases and skin reactions, ”says Abdool-Karim.
He emphasizes that people still have to wash their hands or use a hand sanitizer on a regular basis, as this will certainly curb the spread of Covid-19.
Elijah Mahlanga, spokesman for the Department of Basic Education, did not respond to inquiries on Wednesday.
