Pneumonia is a bacterial disease caused by Streptococcus pneumoniae or Haemophilus influenzae. Pneumonia is characterized with accumulation of fluid or pus in the lungs. The pus develops as a result of inflammatory responses against pathogens that attack and destroy the alveoli in the lungs. This results in difficulty in breathing and other symptoms such as cough, fever, chills etc. Hence statements II and III are correct.
Pneumonia spreads by droplet infection. A healthy person acquires the infection by inhaling the droplets released by an infected person through coughing or sneezing. Sharing of objects with an infected person can also lead to disease transmission as these objects will have deposits of the released droplets.
Salmonella typhi is a bacterium that causes typhoid fever in humans. This disease is characterized by sustained fever, weakness, stomach pain, constipation, loss of appetite etc. It spreads through contaminated food and water. Hence statement I is incorrect.
