Recording medical history: 90 years of public health as told by the Weekly Epidemiological Record

On 1 April 1926, a small team of epidemiologists in the Health Office of the League of Nations, Geneva, laboured to bring forth the first Weekly Epidemiological Record (WER). The publication was tasked with a major mission: providing the world with information about disease hazards that, at that time, mostly travelled by sea: plague, cholera, yellow fever, typhus and smallpox. Had they been alive today, it would be interesting to ask those epidemiological midwives whether they imagined that the WER would still be going strong, still informing the world about health threats, 90 years later...

This timeline starts with the birth of the WER in 1926, marking milestones through the years: epidemics, technological breakthroughs, the establishment of the World Health Organization in 1948, the conquest of infectious disease scourges, such as smallpox in 1979 and the ongoing battle against new and re-emerging infectious diseases.

First issue of Weekly epidemiological record (WER)

On 1st April 1926, the Health Office of the Secretariat of the League of Nations published the first issue of the Weekly Epidemiological Record (WER). The WER was initially tasked with informing the world about disease hazards that, at that time, mostly travelled by sea: cholera, plague, yellow fever and typhoid fever.

Yellow fever virus first isolated

The yellow fever virus was first isolated in Nigeria in 27 June 1927, (known as the Asahi strain) then in 1928 a separate strain was isolated in Dakar (the French strain). This then led to development of the first yellow fever vaccine.

1928-09-28 08:20:58

Discovery of penicillin by Sir Alexander Fleming

The fortuitous discovery of penicillin on a mouldy Petri dish by Alexander Fleming launched a new era in medicine. This natural compound, produced by the Penicillium fungus, was found to be toxic to bacteria, but safe for use in humans. The use of penicillin in World War II is credited with saving the lives of hundreds of thousands.

1931-06-27 10:30:39

Plague vaccine

Live attenuated vaccine developed by J. Robic and G. Girard at Madagascar became the first effective plague vaccine. In the following years, mass vaccination campaigns reduced the incidence of the disease in that country tenfold.

1933-10-01 08:28:54

Isolation of Influenza A virus

Influenza A virus, which, when it undergoes ‘antigenic shift’ can cause pandemic influenza, was isolated.

1940-09-28 08:20:58

Penicillin resistant Staphylococcus identified

The discoverer of penicillin, Alexander Fleming, first warned of the potential importance of the development of resistance. Soon the evidence became alarming. In 1946, a hospital in the United Kingdom reported that 14% of all Staphylococcus aureus infections were resistant to penicillin. By 1950, this proportion had increased to 59%. In the 1990s, penicillin-resistant S. aureus had attained levels greater than 80% both in hospitals and in the community.

1944-03-06 10:30:39

On 22 July 1946, 61 member states of the UN adopted and signed the Constitution of the World Health Organization at the International Health Conference in New York .

1947-09-01 06:27:17

Establishment of the WHO Influenza Control Programme

Concerns that antigenic shift could lead to an influenza pandemic on the scale of the 1918–1919 pandemic prompted the World Health Organization to establish an influenza surveillance programme, providing information about the epidemiology of the disease and enabling updating of vaccine formulations. The World Influenza Centre was eventually set up at the National Institute for Medical Research in London with responsibility for collecting and distributing information, carrying out and coordinating laboratory work on influenza and training laboratory workers.

1948-04-07 01:49:28

Official establishment of the World Health Organization (WHO)

Establishment of the Global Influenza Surveillance Network

Although the WHO Influenza Control Programme was established in 1947, it became clear a worldwide network of laboratories was needed to improve surveillance and support countries lacking virology capacity. To overcome these difficulties, an Expert Committee on Influenza was convened in 1952 and recommended the establishment of an extensive international network of laboratories to conduct surveillance and provide WHO with the information it required to advise its Member States on the most effective influenza control measures.

1955-06-01 22:51:20

1955-06-01 22:51:20

Launch of Global Malaria Eradication Programme

The Global Malaria Eradication Programme was approved by the 8th World Health Assembly in Mexico. The campaign succeeded in eliminating malaria from Europe, North America, the Caribbean and parts of Asia and South-Central America. But no major success occurred in sub-Saharan Africa. The programme was abandoned in 1969. In 1992, leaders attending a Ministerial Conference on Malaria in Amsterdam adopted a Global Strategy for Malaria Control that was more realistic, more pragmatic and more sustainable than previous approaches to malaria control.

1957-02-01 14:59:57

In 1961, a major cholera pandemic began in Indonesia and spread rapidly to other countries in Asia, Europe and Africa. The pandemic continued over three decades, eventually reaching Latin America (in 1991), which had been free of cholera for more than a century. The disease spread rapidly in Latin America, causing nearly 400 000 reported cases and over 4000 deaths in 16 countries.

1961-06-01 22:51:20

Discovery of Methicillin-Resistant Staphylococcus aureus

The Staphylococcus aureus bacterium (S. Aureus), a major source of human infection was widely treated with penicillin in the 1940s. However, in the late 1940s and throughout the 1950s, S. aureus developed resistance to penicillin. Methicillin, a form of penicillin, was introduced to counter the increasing problem of penicillin-resistant S. aureus. However, in 1961, British scientists identied the first strains of S. aureus bacteria that resisted methicillin. This was the so-called ‘birth’ of methicillin resistant staphylococcus aureus or MRSA.

1961-06-01 22:51:20

Invention of Oral vaccine against polio

Dr Albert Sabin developed a "live" oral vaccine against polio (OPV), which, due to its ease of administration, rapidly became the vaccine of choice for mass polio immunization programmes.

1963-03-07 16:56:59

1967-05-02 23:12:59

Intensified smallpox eradication began

In the Director-General’s Report to the 19th World Health Assembly, a new strategy was proposed and accepted with special funds authorized. An intensified effort to eradicate the disease began in January 1967. That year, there were more than 10 million cases and 2 million deaths in 43 countries. The basic strategy consisted of two components: carefully monitored mass vaccination programmes to reach 80% of the population and a new approach to disease prevention — surveillance and containment. This required weekly reports of smallpox cases from all health units with special teams to quickly investigate cases and outbreaks.

1968-07-01 21:25:30

“Hong Kong Flu” A (H3N2) pandemic

In 1968, an antigenic shift to a new influenza subtype, H3N2, caused a pandemic now known as the ‘Hong Kong flu’. It was the third flu pandemic in the 20th century, following the ‘Spanish flu’ in 1918 and the ‘Asian flu’ in 1957. Although the case-fatality rate for this pandemic was lower than that for the ‘Spanish flu’, it still caused about one million deaths.

1969-03-07 16:56:59

Rubella vaccine licensed

The first rubella vaccine—a live, attenuated vaccine—was licensed in 1969. It was developed by the prolific vaccine researcher Maurice Hilleman, using rubella virus obtained from scientists Paul Parkman and Harry Meyer. Hilleman’s rubella vaccine was used in the combination measles-mumps-rubella (MMR) vaccine, which was licensed in 1971.

1969-05-21 00:00:00

Its use revolutionized treatment of tuberculosis, drastically reducing the necessary treatment time.

1972-12-11 08:28:54

The automatic telex reply service

An automatic telex reply service (ATRS), operating from WHO Headquarters, Geneva, was established on 11 December 1972 to inform Member States promptly of the occurrence of communicable diseases of international importance. Each Friday information intended for publication in the Weekly Epidemiological Record (WER) was summarized and fed into the machine for automatic transmission. This enabled national health administrations to obtain important information well before the WER reached them.

1973-09-01 23:50:23

First formal recommendation on influenza vaccine composition issued

Formal recommendations for virus strains to be included in influenza vaccines were first issued by WHO in 1973, based on data compiled through the Global Influenza Surveillance Network (renamed the Global Influenza Surveillance and response System in 2009).

These UN agencies constitute the sponsoring agencies of OCP. The programme stretched over 1 200 000 Km² to protect 30 million people in 11 countries from the river blindness.

1974-04-01 21:58:01

Expanded Programme on Immunization (EPI)

In May 1974, the 27th World Health Assembly resolved to build on the success of the smallpox eradication programme and established the Expanded Programme on Immunization (EPI) to ensure that all children, in all countries, could benefit from life-saving vaccines. The EPI recommended the use of vaccines to protect against six diseases: tuberculosis (BCG), diphtheria, tetanus, pertussis (DTP vaccine), measles and poliomyelitis.

1975-02-01 21:58:01

Alma-Ata Conference

The Declaration of Alma-Ata was adopted at the International Conference on Primary Health Care (PHC), Almaty (formerly Alma-Ata), Kazakhstan (formerly Kazakh Soviet Socialist Republic), 6-12 September 1978. It set the historic goal "Health for all" which assumed that enlightened policy could raise the level of health in deprived populations and thus drive overall development. The declaration broadened the medical model to include social and economic factors, and acknowledged that activities in many sectors, including civil society organizations, shaped the prospects for improved health. Fairness in access to care and efficiency in service delivery were overarching goals.

1979-10-01 08:28:54

Eradication of smallpox

The global eradication of smallpox was certified, based on intense verification activities in countries, by a commission of eminent scientists on 9 December 1979. It was then endorsed by the World Health Assembly on 8 May 1980.

1981-01-01 08:28:54

HIV/AIDS epidemic

Since the beginning of the epidemic, almost 78 million people have been infected with the HIV virus and about 39 million people have died of HIV. Globally, 35.0 million (33.2–37.2 million) people were living with HIV at the end of 2013. An estimated 0.8% of adults aged 15–49 years worldwide are living with HIV, although the burden of the epidemic continues to vary considerably between countries and regions. Sub-Saharan Africa remains most severely affected, with nearly 1 in every 20 adults living with HIV and accounting for nearly 71% of the people living with HIV worldwide.

1981-05-21 00:00:00

WHA Resolution WHA44.9 to eliminate leprosy as public health problem

In 1991 WHO committed itself to promoting the elimination of leprosy as a public health problem by the year 2000 and pledged support to its member states in achieving this goal. The elimination of leprosy as a public health problem is defined as the reduction of prevalence to a level below one case per 10 000 population.

1994-01-12 15:53:14

Global Strategy for Malaria Control

Following the abandonment of the Global Malaria Eradication Programme in 1969, a number of major agencies withdrew their support for malaria programmes. The economic crisis of the early 1970s contributed to an accelerated contraction of funding for malaria control. Malaria resurgences were reported in areas where transmission had been successfully reduced. In 1992, leaders attending a Ministerial Conference on Malaria in Amsterdam agreed to launch a renewed attack on malaria that was more realistic, more pragmatic and more sustainable than previous approaches to malaria control. A WHO Global Strategy for Malaria Control was unveiled the following year.

1995-02-01 06:38:29

The International Commission for the Certification of Dracunculiasis Eradication established

In 1995, to eradicate dracunculiasis (Guinea worm), WHO established an independent International Commission for the Certification of Dracunculiasis Eradication (ICCDE). Since its establishment in 1995 to the end of 2013, the ICCDE has certified 197 countries, territories and areas (belonging to 185 Member States) as free of dracunculiasis. The latest to attain this status in December 2013 include formerly endemic countries Côte d’Ivoire, Nigeria and Niger.

1995-03-20 06:10:19

Directly Observed Treatment, Short-Course (DOTS) strategy launched

DOTS or Directly Observed Treatment Short course is a an approach for tuberculosis control that involves providing a short course of treatment given under direct and supportive observation (DOT) and has been recognized as a highly efficient and cost-effective strategy.

1995-05-17 03:01:01

Call for revision of the 1969 International Health Regulations

The growth in international travel and trade, and the emergence or re-emergence of international disease threats and other public health risks prompted the Forty-eighth World Health Assembly (1995) to call for a substantial revision of the International Health Regulations adopted in 1969.

1995-06-01 08:20:58

WHO starts global supply of free Multidrug therapy (MDT) for leprosy

While WHA 44.9 resolution of 1991 had recognised the widespread effectiveness of multidrug therapy (MDT) in treating leprosy, adoption by national leprosy elimination programmes was slow, due to its high cost. To support countries and the more widespread adoption of MDT, WHO took steps to negotiate a donation of funds to procure the drug itself. The Nippon Foundation (TNF) funded this over a five year period 1995-1999 at a total cost of USD 50 million, and WHO procured the MDT in patient friendly blister packs. In collaboration with national programmes, WHO managed the supply to countries using its own agents. Following further negotiations in 1999 with Novartis (the main manufacturer and supplier of MDT) the company agreed to supply WHO with the drugs free of charge. The donation is still ongoing and will run at least until the end of 2020.
