Are you aware of the difference between the risk and transmission?

Image
Coronavirus disease   2019 (COVID-19) is a syndrome induced by infection with the coronavirus that causes severe acute respiratory syndrome (SARS-CoV-2) and is linked to epidemics in crowded settings. Despite its rapid global spread, nonpharmaceutical measures including as physical separation and prompt isolation of symptomatic patients have been reported to be successful in preventing transmission in both institutions and the general public. COVID-19 and influenza (flu) are both infectious respiratory infections caused by distinct viruses. COVID-19 is caused by infection with a coronavirus that was first identified in 2019, while flu is caused by infection with a virus that was first identified in 1918. Time spent with infected individuals appears to be a primary driver of COVID-19 transmission, according to reports describing risk factors for COVID-19 dissemination. More severe disease in the source patient was also recognised as a risk factor for disease diffusion in a research ...

Is Influenza caused by a virus?

Image
  The influenza virus infects the nose, throat, and perhaps the lungs, causing a contagious  respiratory infection . A, B, C, and D are the four kinds of influenza viruses. Human influenza A and B viruses cause seasonal epidemics of illness (known as flu season) in the United States almost every winter. The only influenza viruses that have been known to cause pandemics, or widespread flu outbreaks, are influenza A viruses. Despite the fact that more than 100 viruses can cause a cold, only influenza virus types A, B, and C cause the flu. Viruses of type A and B produce seasonal epidemics. The  flu  is caused by influenza viruses invading the nose, throat, and lungs. When patients with the flu cough, sneeze, or talk, virus-laden droplets are thrown into the air, potentially landing in the mouths or nostrils of others around. The influenza virus affects your respiratory system, which includes your nose, throat, and lungs. Despite the fact that influenza is commonly refe...

Why are infectious diseases more common in the tropics?

Image
As a result of increased human mobility and climate-driven vector movement, several   tropical diseases   began to spread into temperate climates. Poverty, a lack of clean water, and a lack of medical treatment all influenced the impact of a wide variety of tropical diseases. Exploration of tropical rainforests by humans, deforestation, rising immigration, and greater international air travel and other tourism to tropical regions have resulted in an increase in the occurrence of such diseases in non-tropical countries. Asia currently has the highest number of NTDs, followed by the huge emerging market economies of India, Indonesia and China. Pathogens of various varieties can be found in developing countries; poverty and hunger exacerbate the severity of prevalent diseases; and pathogen transmission is facilitated by poor infrastructure (e.g., water supply, sewage system and hospital hygiene).  Dengue fever, yellow fever, rotavirus, AIDS, Ebola and Lassa fever are ex...

How do tropical diseases spread?

Image
  Tropical disease   any disease that is native to or occurs primarily in tropical or subtropical areas of the world is referred to as a tropical disease. Malaria, cholera, Chagas disease, yellow fever and dengue fever are examples of tropical diseases. Tropical diseases thrive in the tropics hot and humid climate. Viruses, bacteria and parasites cause them and they spread by airborne transmission, sexual contact and contaminated food and water sources.
