can anyone tell the first disease that occured in human beings

No specific diease. Why do you need this answer, i am sure no one will ever ask u this. Because that is a stupid question which no one has ever discovered and there is no need for that too

its influenza as it may occur even due to the change in  your surrounding weather conditions.thus, it is more likely to occur.

u r correct.i know that is a stupid question but not like u stupid. u tell me respectedly dont use bad words.how dare u use bad words just noe tell me sorry.
