They should not be used on the skin, as this can be dangerous. It is also not recommended to sniff it.
They could be harmful to mucous membranes.
The WHO said: 'Be aware that both alcohol and chlorine can be useful to disinfect surfaces, but they need to be used under appropriate recommendations.'
6. Thermal scanners won't always detect infected people
Thermal scanners are being used worldwide at airports and railway stations. They can detect people with a fever - a temperature higher than normal.
'However, they cannot detect people who are infected but are not yet sick with fever,' the WHO said.
It takes two to ten days before people who are infected become sick and develop a fever. In some people, it's taken 14 days.
7. Letters or packages from China do not carry coronavirus
It is safe to receive packages from China, the WHO said. Analysis shows coronaviruses do not survive very long on objects - especially flying between countries.
People questioned exactly how novel coronavirus spreads and if it can arrive by mail.
There is nothing to suggest this is the case.
8. Pets can't get ill with coronavirus
At present, there is no evidence that pets can be infected by coronavirus.
Chinese nationals have made make-shift face masks for their cats who fear their felines could catch the deadly virus.
Such measures are unnecessary, the WHO said.
The agency added: 'It is always a good idea to wash your hands with soap and water after contact with pets. This protects you against various common bacteria such as E.coli and Salmonella that can pass between pets and humans.'
There is no evidence that regularly rinsing the nose with saline has protected people from infection with the novel coronavirus, the WHO said.
Some evidence suggests the old wives tale can help people recover more quickly from the common cold because cells in the body use the chloride in salt to produce hypochlorous acid (HOCI) which is the active ingredient found in bleach.
