Coronavirus disease (COVID-19) is an infectious disease caused by the SARS-CoV-2 virus. Most people infected with the virus will experience mild to moderate respiratory illness and recover without requiring special treatment. However, some will become seriously ill and require medical attention. epidemic: an infectious disease outbreak that is spreading rapidly through a community. pandemic: an epidemic that affects people throughout a large region or across multiple continents. When CDC estimates that flu-related hospitalizations since 2010 ranged from 140,000 to 710,000, while flu-related deaths are estimated to have ranged from 12,000 to 56,000. Rates of medical visits, complications, hospitalizations and death can range from moderate to high. Number of deaths could be much higher than seasonal flu (e.g. Yet a pandemic is defined as the "worldwide spread" of a new disease. The last pandemic reported in the world was the H1N1 flu pandemic in 2009, which killed hundreds of thousands globally. The difference between an epidemic and a pandemic isn't the severity of the disease, but the degree to which the disease has spread. When a disease exists all the time in a specific region or Pandemic refers to an epidemic that has spread across countries and continents — the worldwide spread of a new disease. "Pandemic is not a word to use lightly or carelessly," warned Dr Tedros Adhanom Ghebreyesus, director general of the WHO, and claimed the global health body had previously avoided using the term because it didn't want But unlike a pandemic or epidemic, in which a disease's behavior is often surprising or unexpected, an illness that has become endemic has become more predictable. A candy analogy might help. Cholera is an extremely virulent disease transmitted through the ingestion of contaminated food or water (2). Cholera can cause severe acute watery diarrhoea and the severe forms of the disease can kill within hours if left untreated. Most people infected with V. cholerae do not develop any symptoms, although the bacteria are present in their The word pandemic, on its own, however, doesn't tell us anything about how serious the impact of the disease will be. Pandemics can be both mild and severe, depending on the disease itself. The most recent pandemic, for example, was in 2009 with the global spread of the H1N1 strain of influenza. While the outbreak formally reached pandemic A recent pandemic was the influenza A H1N1 pandemic of 2009, and two current pandemics are the human immunodeficiency virus (HIV) and the coronavirus disease 2019 (COVID-19) outbreaks. uC0i2U.
