This document summarizes a presentation on acute respiratory infections (ARI). It begins by defining upper and lower ARI, including common types like pneumonia. Pneumonia is then discussed in more detail, noting that it accounts for 90% of ARI deaths, is a leading cause of childhood death worldwide, and has a high burden in India. Epidemiological determinants of ARI are presented, including infectious agents like bacteria and viruses, and host/environmental factors. The integrated management of neonatal and childhood illness approach is described for assessing, classifying, and treating ARI in children. Prevention strategies like immunization, nutrition, and the WHO's global action plan for pneumonia are also outlined.

21-02-2019 11Dr Tanveer Rehman PSM JIPMER

12. Epidemiological determinants
1. Transmission
2. The viruses and bacteria that are commonly found in a child's nose or
throat, can infect the lungs if they are inhaled. They may also spread via
air-borne droplets from a cough or sneeze. In addition, pneumonia may
spread through blood, especially during and shortly after birth. More
research needs to be done on the different pathogens causing pneumonia
and the ways they are transmitted, as this is of critical importance for
treatment and prevention.

26. Global action plan for pneumonia and diarrhoea
(GAPPD)
The WHO and UNICEF integrated response
• protect children from pneumonia including promoting exclusive breastfeeding and
adequate complementary feeding;
• prevent pneumonia with vaccinations, hand washing with soap, reducing household
air pollution, HIV prevention and cotrimoxazole prophylaxis for HIV-infected and
exposed children;
• treat pneumonia focusing on making sure that every sick child has access to the
right kind of care -- either from a community-based health worker, or in a health
facility if the disease is severe -- and can get the antibiotics and oxygen they need
to get well;
• a 75% reduction in incidence of severe pneumonia and diarrhoea from 2010 levels
among children under five, and the virtual elimination of deaths from both diseases
in the same age-group.
