According to the World Health Organization (WHO) Friday, flu cases have reduced worldwide, reaching miniscule levels.

Epidemiologists and other experts thought that the COVID-19 restrictions imposed worldwide, aided the 'disappearance' of the common flu and other influenza.

Data showed that flu cases are significantly lower than usual, said WHO, considering that COVID-19 and the influenza are spread in a similar manner.

However, public health experts warned that this may not be hopeful news.

They said that the lower flu cases could lead to a loss of immune responses among citizens of the world.

But, the WHO remained hopeful that seasonal flu shots will remain effective despite this.
