HOW COPERNICUS SUPPORTS EMERGENCY RESPONSE

Since February 2014, West Africa has been facing the most severe ebola outbreak recorded in history. Although the virus can only be transmitted by close contact with body fluids, health workers, family members and others in close contact with sick people and deceased patients are especially at risk. Fruit bats are considered to be one of the natural hosts of the ebola virus; intermediate hosts can be monkeys, apes or pigs. The infection then spreads through these animals. To fight this lethal disease, the European Commission has made available €180 million. This funding will help contain the spread of the epidemic and provide immediate health care to the affected communities. In Europe, strict measures are taken to avoid the outbreak of this virulent disease.
Satellite data help identify areas prone to the emergence and spreading of epidemics such as ebola, malaria, meningitis or dengue fever. By monitoring parameters like land cover, water bodies, wind or dust, satellites support preparedness, early warning, surveillance and quick response to disease outbreaks. In the case of ebola, satellites help to identify potential areas where initial contact with the virus may take place. Such areas are isolated rural settlements surrounded by dense tropical forests and
oil palm cultivations. These are likely to attract fruit bats, one of the main vectors of the virus.
Satellites provide accurate and timely information in the form of land cover reference maps that can then be combined with census data. Furthermore, satellites help to plan and support logistical operations for emergency management to tackle the spread of ebola outbreaks.

SENEGAL

LIBERIA

SIERRA LEONE
Liberia is experiencing cases of ebola with numerous deaths. Epidemiologists seek to identify isolated rural settlements surrounded by dense tropical forests and oil palm cultivations. These are likely to attract fruit bats, which are one of the main vectors of the ebola virus. The reference map shows besides oil palms and tropical forest also features such as roads and buildings in the area of Kwendin, Liberia. Such information supports identification of areas at risk and emergency response operations. Source: ESA / G-ECO-MON / GeoVille; Image: DigitalGlobe

> Improve the development of Earth observation methodologies to pinpoint areas at risk of ebola, malaria, meningitis or dengue fever
> Enhance capacity and integrate Earth observation techniques in disease control programmes
Fruit bats are a natural host of the ebola virus.
The Copernicus Emergency Management Service makes use of satellite data to provide regular and detailed geo-spatial information. Such information is used in modelling the prevalence and spread of diseases.
Copernicus thereby supports disease vector control and management programmes, particularly in Africa.

> Land cover parameters such as oil palm cultivations, water bodies and general vegetation cover
> Parameters related to emergency management such as infrastructure and settlement maps
Copernicus Contribution Next Steps
From malaria to ebola, infectious diseases may not be able to hide for long. Copernicus satellites are increasingly used to pinpoint areas at risk of disease outbreaks.
