The significance of the number 2.8 million depends on the context. In a pandemic situation, having 2.8 million cases could indicate a severe public health crisis. For instance, in the early months of the COVID-19 pandemic, reaching 2.8 million confirmed cases marked a critical point in understanding the scale and spread of the virus. Conversely, in the context of a preventative campaign, vaccinating 2.8 million people could be seen as a major success in reducing disease transmission.
