The Covid-19 Pandemic. With the acute phase of the Covid-19 pandemic fading even as the coronavirus persists and evolves, a new normal is taking shape around the world. Kenny Holston for The New COVID-19, also called coronavirus disease 2019, is a sickness caused by a virus called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This virus is a coronavirus. Coronavirus is a family of viruses that can cause illnesses such as the common cold, severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS). The Black Death (also known as the Pestilence, the Great Mortality or the Plague) was a bubonic plague pandemic occurring in Western Eurasia and North Africa from 1346 to 1353. It is the most fatal pandemic recorded in human history, causing the deaths of approximately 40% to 60% of the Europe's population (an estimated 25-50 million people) peaking in Europe from 1347 to 1351. Six months into the pandemic, people are looking for ways to make sense of what's happening. Talking about waves of disease, with the implication of predictable rises and falls, is part of that. As an epidemiologist, I know that disease waves aren't scientifically defined. But looking to the history of previous epidemics and other countries Respirators (for example, N95) are made to protect you by fitting closely on the face to filter out particles, including the virus that causes COVID-19. They can also block droplets and particles you breathe, cough, or sneeze out so you do not spread them to others. Respirators (for example, N95) provide higher protection than masks. Preparing and preventing epidemics and pandemics. The number of high-threat infectious hazards continues to rise; some of these are re-emerging and others are new. While outbreaks of vaccine-preventable infectious diseases, such as meningococcal disease, yellow fever and cholera, can have disastrous effects in areas with limited health .
