There are no countries currently experiencing widespread and intense disease transmission. However, sporadic outbreaks of Ebola have been occurring in Africa for decades. There is also evidence to suggest that a very small proportion of survivors of Ebola infection may see the disease reactivate in an infectious form. Thus countries where an Ebola outbreak has recently ended may see isolated cases for an unknown period of time.
More information on the Ebola situation can be found on the World Health Organization website.
Previously affected countries
On 29 December 2015, WHO declared Guinea free of Ebola virus transmission, as 42 days have passed since the last confirmed case had a second negative blood test.
On 7 November 2015, WHO declared Sierra Leone free of Ebola virus transmission, as 42 days have passed since the last confirmed case had a second negative blood test.
On 9 May 2015, WHO declared Liberia free of Ebola virus transmission as 42 days have passed since the last laboratory-confirmed case was buried.
Countries with an initial case or cases, or with localised transmission
A number of countries have had initial cases or localised transmission of Ebola. These countries have since been declared free of Ebola transmission by the World Health Organization.
Visit the World Health Organization website to find the most up-to-date information on these countries.
New Zealand risk assessment
The Ministry of Health assessment is that the risk to New Zealand from Ebola remains extremely low.
New Zealand has now ceased the additional border screening that was implemented for individuals arriving from West African countries affected by the Ebola outbreak; however, there are routine border systems in place for managing ill travellers. An Ebola Technical Advisory Group was established so the Ministry could check its precautions, guidance and activities are appropriate.
The Ministry of Health will continue to monitor the situation internationally, and consider advice from the World Health Organization and other countries in relation to Ebola cases in West Africa or other countries.
West Africa Ebola outbreak
The outbreak, which began in West Africa in December 2013, was the largest ever reported both in terms of the number of cases and the geographic spread. It was also the first time Ebola had spread to large cities and outside Africa.
Unlike New Zealand, the countries affected by the outbreak in West Africa have fragile health systems. This made diagnosing cases of Ebola, isolation of infected patients, and prevention and control of the disease very difficult.
Travel restrictions were imposed during the outbreak in a number of affected and neighbouring countries which significantly impacted freedom of movement.
