Bronchitis is inflammation of the bronchi (large and medium sized airway) in the lungs that causes coughing . Bronchitis is spread by coughing (airway respiratory droplets) , by saliva (kissing or shared drinks) , by touching contaminated surface , by skin to skin contact (handshakes or hugs). According to the centers for Disease Control & Prevention (CDC). People with certain underlying health conditions may be at higher risk of severe illness from Covid-19 especially if they do not have these conditions under control. Bronchitis does not cause Covid-19 (Coronavirus Disease 2019) and based on current information it dose not appear to increase a person’s risk of developing the disease. Like bronchitis Covid-19 also affects the respiratory tract , including the lungs. It can therefore lead to Pneumonia or Acute Respiratory Disease. Acute Bronchitis affects more than 40 in 1000 adults per year in U.K. and 10 million peoples per year in India. The causes are usually considered to be infective , but only around half of peoples have identifiable pathogens. The role of smoking is susceptible to acute bronchitis is unpredictable. The large number of IBV (Infectious Bronchitis Virus) lives worldwide, some being unique to a particular area, others having a more general distribution.
