In planning for a possible influenza pandemic, the WHO published a document on pandemic preparedness guidance in 1999, revised in 2005 and 2009, defining phases and appropriate actions for each phase in an aide-mémoire titled WHO pandemic phase descriptions and main actions by phase.

In 2006, the HIV prevalence among pregnant women in South Africa was 29%.
The PSAF superseded the 2007 linear Pandemic Severity Index, which assumed 30% spread and measured case fatality rate (CFR) to assess the severity and evolution of the pandemic. Historically, measures of pandemic severity were based on the case fatality rate.
In February 2020, a WHO spokesperson clarified that "there is no official category [for a pandemic]". In a virtual press conference in May 2009 on the influenza pandemic, Dr.

On 11 March 2020, the World Health Organization characterized the spread of COVID-19 as a pandemic, marking the first global pandemic since the 2009 swine flu pandemic.
The phases are defined by the spread of the disease; virulence and mortality are not mentioned in the current WHO definition, although these factors have previously been included. In 2014, The United States Centers for Disease Control and Prevention introduced an analogous framework to the WHO's pandemic stages titled the Pandemic Intervals Framework.
It includes two pre-pandemic intervals, Investigation Recognition and four pandemic intervals, Initiation Acceleration Deceleration Preparation It also includes a table defining the intervals and mapping them to the WHO pandemic stages. === Severity === In 2014, the United States Centers for Disease Control and Prevention adopted the Pandemic Severity Assessment Framework (PSAF) to assess the severity of pandemics.
As of 2019, there have been 1.7 millions of infections of HIV/AIDS and about a total of 32.7 million deaths related to HIV/AIDS (by the time the pandemic started in 1981 until 2019). === COVID-19 === SARS-CoV-2, a new strain of coronavirus, was first detected in the city of Wuhan, Hubei Province, China, in late December 2019.
