Ebola Outbreak in Liberia : August 2014Amit Bhagat
This report is about the Outbreak of Ebola Virus Disease (EVD) (also known as Ebola Hemmorhagic fever) in Liberia, which occurred mainly in most parts of the West Africa starting from Guinea and reaching to heart of Sierra Leone, Liberia, Nigeria and most other places. EVD is an epidemic disease and also highly infectious. This disease is very severe, rare and deadly, with a fatality rate of approx 90%. There is no such cure or vaccine is present, only some experimental drugs have been using (till date). Thus, many organizations viz WHO, CDC, Red Cross etc are working for prevention and relief of patients to fight against this epidemic disease.

In light of the of the Ebola outbreak in West Africa the Yale-Tulane ESF-8 Planning and Response Program has produced this special report.
Since most of our student are not back yet from summer break I reached out to past alumni and members of Team Rubicon to assist in putting this report together.
The report was compiled entirely from open source materials. Please feel free to forward the report to anyone who might be interested.
Any students, past alumni, or volunteers who would like to work on future slides let me know. Assistance is always welcome.
E-bola virus had caused the majority of human deaths from EVD, and was the cause of the 2013–2015 E-bola virus epidemic in West Africa , with confirmed death of people around 11k +
The Ebola virus causes an acute, serious illness which is often fatal if untreated. Ebola virus disease (EVD) first appeared in 1976 in 2 simultaneous outbreaks, one in Nzara, Sudan, and the other in Yambuku, Democratic Republic of Congo. The latter occurred in a village near the Ebola River, from which the disease takes its name.
The current outbreak in west Africa, (first cases notified in March 2014), is the largest and most complex Ebola outbreak since the Ebola virus was first discovered in 1976. There have been more cases and deaths in this outbreak than all others combined. It has also spread between countries starting in Guinea then spreading across land borders to Sierra Leone and Liberia, by air (1 traveller only) to Nigeria, and by land (1 traveller) to Senegal.
The most severely affected countries, Guinea, Sierra Leone and Liberia have very weak health systems, lacking human and infrastructural resources, having only recently emerged from long periods of conflict and instability. On August 8, the WHO Director-General declared this outbreak a Public Health Emergency of International Concern.
A separate, unrelated Ebola outbreak began in Boende, Equateur, an isolated part of the Democratic Republic of Congo.
The virus family Filoviridae includes 3 genera: Cuevavirus, Marburgvirus, and Ebolavirus. There are 5 species that have been identified: Zaire, Bundibugyo, Sudan, Reston and Taï Forest. The first 3, Bundibugyo ebolavirus, Zaire ebolavirus, and Sudan ebolavirus have been associated with large outbreaks in Africa. The virus causing the 2014 west African outbreak belongs to the Zaire species.

Fighting Against Ebola: Public Health and NepalMMC, IOM, Nepal
Ebola is not just a clinical manifestation but is seen as more of a Global health injustice issue to developing nations. And, Nepal being one of those developing nations, is it ready for the potential Ebola outbreak?
In the absence of effective treatment and a human vaccine, raising awareness of the risk factors for Ebola infection and the protective measures individuals can take is the only way to reduce human infection and death.
Ebola virus disease (EVD), formerly known as Ebola haemorrhagic fever, is a severe, often fatal illness in humans.
EVD outbreaks have a case fatality rate of up to 90%.
EVD outbreaks occur primarily in remote villages in Central and West Africa, near tropical rainforests.
The virus is transmitted to people from wild animals and spreads in the human population through human-to-human transmission.
Fruit bats of the Pteropodidae family are considered to be the natural host of the Ebola virus.
Severely ill patients require intensive supportive care. No licensed specific treatment or vaccine is available for use in people or animals.
This is a final year project report on Ebola Virus Disease.....

Public Health Response to Ebola Statement of Dr. FriedenDawn Dawson
House Energy and Commerce Committee Subcommittee on Oversight and Investigations Public Health Response to Ebola October 16, 2014
Statement of Dr. Thomas R. Frieden, M.D., M.P.H.
Director, Centers for Disease Control and Prevention
1. 18 October 2014
Ebola patients treated outside West Africa* (updated 15 Oct 2014)
*In all but 3 cases, the patient was infected with Ebola while in West Africa. Infection outside Africa has been restricted to health workers in Madrid and in Dallas. DR Congo has also reported a separate outbreak of an unrelated strain of Ebola.
Ebola virus was first identified in Sudan and Zaire in 1976. It belongs to the family of Filoviridae.
It causes Ebola Virus Disease (EVD), formerly known as Ebola Hemorrhagic Fever. EVD is a rare disease which causes severe, often fatal illness in humans. There are 5 different species of Ebola virus identified and isolated from different regions in Africa. The different species has different infectivity and mortality in humans. The Zaire species is the most virulent and can result in up to 90% mortality in humans who are infected with it.
Outbreaks occur primarily in remote villages in Central and West Africa. The current outbreak of EVD in West Africa started in March 2014.
2. The 2014 Ebola epidemic is the largest in history, affecting multiple countries. As of 15 Oct 2014, WHO released new figures stating that more than 8,997 confirmed, probable and suspected cases have been reported in seven affected countries: Liberia, Nigeria Guinea, Sierra Leone, Senegal, Spain, and the United States of America. 4493 people have died. (Case fatality rate of about 50%). The situation in Guinea, Liberia, and Sierra Leone is deteriorating, with widespread and persistent transmission of EV. These severely affected countries have very weak health systems, lacking human and infrastructural resources. WHO estimates that Liberia's number of Ebola cases is likely even greater than the number that has been reported as there is difficulty gathering data in Liberia.
In Nigeria, there have been 20 cases and 8 deaths. In Senegal, there has been one travel-associated case. Nigeria and Senegal have not reported any new cases since September 5, 2014, and August 29, 2014, respectively. In Spain there has been one case. These cases are thus considered to be contained, with no further spread in these countries (localized transmission).
In the United States (Dallas, Texas), 2 cases and 1 death have been reported. The first index case in US involved an imported case in a man who had traveled to Dallas, Texas from West Africa on 30 September 2014. The patient did not have symptoms when leaving West Africa, but developed symptoms approximately four days after arriving in the United States. The person sought medical care at Texas Presbyterian Hospital of Dallas after developing symptoms consistent with Ebola. He died of Ebola on October 8 and was cremated. On October 10, a healthcare worker at Texas
Presbyterian Hospital who provided care for the index patient fell ill and was tested positive for Ebola, and is currently being treated at Texas Health Presbyterian Hospital Dallas.
On October 14, a second healthcare worker at Texas Presbyterian Hospital who also provided care for the index patient reported to the hospital with a low-grade fever and was isolated. The healthcare worker tested positive for Ebola; she however, travelled by a Frontier airlines flight on 13 October evening, the day before she reported symptoms. In view of the proximity in time between the evening flight and first report of illness the following morning, CDC is now reaching out to 132 passengers who flew on Frontier Airlines flight 1143 Cleveland to Dallas/Fort Worth Oct. 13.
CDC is also working with other U.S. government agencies, the World Health Organization (WHO), and other domestic and international partners and has activated its Emergency Operations Center to help coordinate technical assistance and control activities with partners. CDC has also deployed teams of public health experts to West Africa and will continue to send experts to the affected countries.
3. (Adapted from http://www.cdc.gov/vhf/ebola/resources/virus-ecology.html)
In an Ebola virus outbreak, the virus is transmitted through direct contact of broken skin or mucous membranes with blood, stool, vomitus, urine, saliva and tissues of symptomatic persons or animals, or indirect contact with environments contaminated with such fluids. Humans may also be infected through exposure to secretions or excretions of bats. Infection can also be acquired through ingesting the meat of infected primates (apes, gorilla, and chimpanzees) and animals.
Those at highest risk of infection are:
health workers;
family members or others in close contact with infected people;
mourners who have direct contact with the bodies of the deceased as part of burial ceremonies.
Other risk factors include:
hunters in the rain forest who come into contact with dead animals found lying in the forest.
4. The incubation period of EVD varies from 2 to 21 days, usually 5 to 10 days. Patients are not contagious during the incubation period. Infected individuals become contagious only when they manifest symptoms.
Symptoms usually begin as a flu-like syndrome (sudden onset of fever, chills, general malaise, muscle pain, joint pain, headache, non-productive cough and sore throat).
Other symptoms that may follow include nausea, vomiting, diarrhea, abdominal pain, non-itchy rash.
As the illness progresses, kidney and liver function become impaired and in some cases, patients start developing internal or external bleeding.
Ebola virus infections can only be confirmed through laboratory testing, which detect:
antibodies,
viral antigen (ELISA assays),
Ebola RNA by reverse-transcription polymerase chain reaction (PCR),
Viral cultures and isolation may also be performed with infected material / specimens
There is currently no specific treatment for Ebola virus infection. Management is supportive, which may include oxygen, blood transfusion and fluids.
5. (1) Can I still travel to Africa or any of the affected countries?
You are encouraged to refer to the MOH web page on Ebola for the latest Health Advisory, before travelling to West or Central Africa. You should consider postponing travel to countries with reported Ebola Virus Disease activity, if it is non-essential.
(2) How do I prevent myself from being infected?
There is currently no vaccine against Ebola virus infection available. The risk of infection can be significantly reduced by barrier techniques; through the use of wearing appropriate protective equipment, such as masks, gloves, and gowns, eye shields, and regular hand washing.
(3) What’s the situation in Singapore?
There has not been any reported case of Ebola in Singapore. MOH has been closely watching the Ebola situation, including developments in Spain and the United States. These show that an imported case and the potential for community exposure from imported cases cannot be ruled out.
(4) What is Singapore doing to control the spread of Ebola?
Singapore had stepped up additional screening measures at arrival halls in Singapore Changi Airport with effect from 15 Oct, 12 noon. Nationals and travellers from countries with reported Ebola Virus Disease activity (currently Guinea, Liberia, Sierra Leone, Nigeria, Senegal and Democratic Republic of Congo) will be directed to a screening station, where they will be screened for temperature and exposure to Ebola through a Health Declaration Card, which will include their contact details in Singapore.
How not to spread and/or catch Ebola
Strict isolation of the infected patients,
Avoid direct contact with sick patients as the virus is spread through contaminated body fluids
Proper personal protective equipment for the people in contact with the patients,
Proper handling and disposal of remains. Clothing and clinical waste should be incinerated and any medical equipment that needs to be kept should be decontaminated
Maintain good personal hygiene
People who recover from Ebola should abstain from sex or use condoms for three months
6. Travelers who are cleared will then be directed to the duty desk at the arrival hall, where they will clear immigration control. Those who are found to have a fever will be transported in an appropriate ambulance transport to Tan Tock Seng Hospital for further medical assessment. Travellers who are well but who are identified as having possible exposure to Ebola virus infection will be quarantined or put under surveillance depending on the risk assessment. Measures are in place to carry out contact tracing and quarantine of all close contacts, in the event of an imported case.
Aside from Singapore Changi Airport, a Health Declaration Card will also be implemented at land and sea checkpoints, as well as at Seletar Airport.
(4) What should I look out for if I need to travel to Africa or any of the affected countries?
If your travel to these countries is necessary, it is advisable that you closely monitor the advice provided by local health authorities and the WHO.
You must maintain strict hygiene standards such as hand hygiene and avoid any direct contact with patients with Ebola or unknown illnesses and any objects that may be contaminated with bodily fluids. Hospital visits are strongly discouraged.
You must also avoid contact with wild animals such as chimpanzee or gorillas (especially if the animal has been sick) and avoid eating or handling raw or undercooked animal products, such as blood and meat. Exploration of caves that may be inhabited by bats should be avoided.
If you should fall ill with symptoms described above and you have possible exposure history, consult the doctor immediately.
(5) What should I do if I fall ill after returning from Africa or any of the affected countries?
Returning travellers from countries with reported Ebola Virus Disease activity or travellers who suspect that they have been exposed to Ebola virus should seek immediate medical attention, if they develop any disease symptoms within 3 weeks of their return. They should inform their doctor of their recent travel or contact history.
EVD should be considered as a possible diagnosis in individuals who presented with the following symptoms and travel history:
A person with a fever (>38 C) or history of sudden onset of high fever AND has travelled in particular regions in West Africa (currently Guinea, Liberia, and Sierra Leone) within 21 days, OR
A person with fever (>38 C) or history of sudden onset of high fever AND has cared for or come into contact with body fluids (blood, urine, faeces, tissues, laboratory cultures) from an individual known or strongly suspected to have EVD.
