Is influence 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 referred to as "th...

How do infectious diseases impact our society?

Infectious diseases, particularly HIV/AIDS and malaria, have high economic impacts. Their rising toll on productivity as a result of deaths and chronic debilitating illnesses, reduced profitability and decreasing foreign investment has stifled certain poor countries' economic growth. Diseases have the potential to effect people not only physically, but also mentally, as contracting and living with a sickness can change a person's outlook on life. Natural causes refer to death caused by sickness. The majority of infectious infections have just modest side effects. However, some illnesses such as pneumonia, AIDS and meningitis can be fatal. A few infections have been related to an increased risk of cancer over time: Cervical cancer is connected to the human papillomavirus. The World Health Organization put two infectious diseases, lower respiratory infections and diarrheal diseases in the top 10 causes of mortality globally. Climate change, globalisation and urbanisation are al...

What are infectious diseases so important to us ?

Image
  Infectious diseases are illnesses brought on by bacteria, viruses, fungus, or parasites. Our bodies are home to a variety of creatures. In most cases, they're innocuous or even beneficial. However, some microbes can cause sickness under particular circumstances. Every year, new, potentially hazardous bacteria, viruses, fungi and parasites arise, such as SARS (severe acute respiratory syndrome). Pathogens that have previously been identified can develop to become resistant to antibiotics and other therapies. We are also more prone to the transmission of infectious pathogens due to population density and easy mobility. Concerns about bio terrorism have re-ignited interest in illnesses that have been eradicated or are extremely rare, such as smallpox and anthrax. With its ability to cure and prevent disease, identify particular disease causes (microbes) and deal with different, often catastrophic outbreaks, infectious diseases is a vast subject that is almost unique in current m...
