The world war started in silence against the unseen enemy since the beginning of 2020. Just created black smokes disturbing global temperature and so many showdowns were completed all over the world to set the accuracy of nuclear weapons for many decades. Nature has showed its revenge by the smallest weapon so far and we are calling it the deadliest one in this 21st century.
We know about the global influenza pandemic of 1918-1919, which killed more than 20 million people worldwide, and the HIV/AIDS pandemic, which began to accelerate in the early 1980s and continues unabated in some parts of the world. In addition, at least 30 other new and reemerging diseases and syndromes have been recognized since the 1970s
New diseases are superimposed on endemic diseases such as diarrheal diseases, malaria, tuberculosis (TB), and measles, which continue to exact a huge toll. Indeed, malaria and TB, among others, are reemerging in a drug-resistant form. Today, infectious diseases remain the leading cause of death worldwide. Many pathogens are becoming increasingly resistant to standard antimicrobial drugs, making treatment difficult and in some cases impossible. Moreover, chronic conditions generally considered noninfectious actually have been found to have a microbial etiology.
