The report published by the World Health Organisation regarding the basic principles to reduce coronavirus infection refutes the claim.
The World Health Organisation has mentioned the basic preventive measures to reduce the general risk of transmission of acute Coronavirus infections. But they have not mentioned about avoiding the cold drinks and ice creams anywhere. (Ref page number. 4).
Hence, it is concluded that there is no scientific evidence suggesting a link between these food items and the novel Coronavirus.
The COVID-19 pandemic has given rise to a lot of potentially dangerous misinformation. For reliable advice on COVID-19 including symptoms, prevention and available treatment, please refer to the World Health Organisation or your national healthcare authority.
