The global morbidity graph is constantly changing, with both ups and downs. Currently, the world is dealing with the corona virus, which is similar to the flu in many ways. However, unlike the flu, which typically appears during winter months, the corona virus is a multi-seasonal virus that seems to be continuously evolving and producing new sub-strains. It’s crucial to observe hygiene rules such as washing your hands well and ventilating rooms. For those at higher risk, getting vaccinated is also recommended.
