                                               neumonia is a leading cause of death and disability
                                               and the leading infectious cause of death in the
                                               world. In 2019, pneumonia caused an estimated
                                               2.5 million deaths across all ages according to the
                                               Global Burden of Disease (GBD).

                             Three-quarters of pneumonia deaths are concentrated
                             among two vulnerable populations—the very young and the
                             very old. An estimated 672,000 pneumonia deaths are among
                             children under five years and 1.2 million deaths are among
                             adults over 69 years. Unlike most other leading infectious
                             disease killers, pneumonia deaths follow a “U-shaped curve”
                             across the life course, peaking in the early and later years of
                             life. 1

                             Pneumonia is truly a “global health” issue that affects every
                             country. Two-thirds of pneumonia deaths cluster in a diverse
                             group of 20 low-, middle-, and high-income countries drawn
                             mostly from Sub-Saharan Africa, South Asia, East Asia and
                             the Pacific, and the Americas. In low-income countries, the
                             burden of pneumonia deaths falls disproportionately on
                             children under five years, while in high-income countries
                             it is adults aged over 69 years who shoulder the burden.
                             Importantly, many middle-income countries carry “double-
                             burdens” of pneumonia deaths, losing both large numbers of

                  Overview
                             children and the elderly each year.

                             Despite recent gains in reducing child pneumonia mortality,
                             progress in reducing all-age pneumonia deaths has not kept
                             pace with other leading infectious diseases in most countries.
                             And pneumonia deaths among adults are rising, including
                             from COVID-19, so that the overall pneumonia burden is
                             increasing in many countries. In fact, deaths from COVID-19
                             could add up to two million deaths to the global respiratory
                             infection death toll for 2020. Even after the pandemic ends,
                             increases in risk-related pneumonia deaths from air pollution,
                             tobacco smoking, and temperature extremes among elderly

Pneumonia deaths are concentrated among
the very young and the very old. Three-

million pneumonia deaths that occurred in                                                                                            382K                                  1.2M

diseases, pneumonia deaths follow a
“U-shaped” curve across the life course,

eastern Central African Republic, southern South Sudan,
and southern Somalia. In Asia, there are sub-national
clusters of child pneumonia mortality risk in northern
Uzbekistan, southern Afghanistan, the Sindh and Khyber
Pakhtunkhwa provinces of Pakistan, and the northern
states of India (e.g., Uttar Pradesh, Bihar, Madhya Pradesh,
and Rajasthan). Governments and global health donors
and agencies should use this data to identify exactly
where the populations of children at greatest risk of death
from pneumonia are located within national borders and
prioritize pneumonia control efforts to them. Because the
geographic areas with the greatest risk of child pneumonia
death may not be the same as the populations with the
greatest numbers of child pneumonia deaths, decision-
makers will need to take into account broader indicators
to identify the largest numbers of children at greatest risk
of death from pneumonia. In the absence of sub-national
maps of adult pneumonia deaths, decision-makers can
identify the populations of elderly at greatest risk by using
sub-national maps of exposure to air pollution and tobacco
smoking as proxies.
