The most dangerous virus outbreak in history
In May 2015, the World Health Organization (WHO) was notified of an outbreak of Ebola virus disease (EVD) in Guinea. The outbreak quickly spread to Liberia, Sierra Leone, and Nigeria. On 8 August 2014, WHO declared the outbreak a Public Health Emergency of International Concern. This was the largest, most complex and most dangerous outbreak of EVD in history.
The outbreak had a devastating effect on the countries involved. Over 28,600 people were infected and 11,315 people died. Health systems were overwhelmed, with too few hospital beds, medicines and trained health workers. Families were torn apart as sick relatives were quarantined and died in isolation. Communities were afraid, leading to widespread panic and mistrust. The economies of the countries affected were also hard hit.
The outbreak was finally brought under control in 2016, but not before it had claimed the lives of too many people and caused untold suffering.
The most dangerous virus outbreak in history started in Guinea in December 2013. The first cases were reported in the village of Meliandou. Ebola is thought to have first emerged in humans in Central Africa in 1976. The outbreak in Guinea was the first time the virus had been detected in West Africa.
The virus is thought to have originated in fruit bats, which are found in abundance in the forests of Guinea. It is believed that a bat infected a human, who then passed it on to others. The outbreak then spread from village to village through human-to-human contact.
The symptoms of Ebola include fever, muscle pain, weakness, headache, vomiting and diarrhoea. In some cases, patients also experience haemorrhaging from the eyes, nose or mouth. Ebola is fatal in around 50% of cases.
There is no specific treatment for Ebola and there is no vaccine. The virus can only be controlled by identifying and isolating patients, tracing and monitoring people who have come into contact with them and ensuring proper burial practices.
The outbreak in Guinea was initially met with skepticism and denial by the authorities. They did not believe that Ebola was the cause of the illness and death. As more people became sick and died, it became clear that this was a serious outbreak.
The WHO was notified in March 2014 and immediately sent a team of experts to Guinea. They were joined by teams from Médecins sans Frontières (MSF) and the Centre for Disease Control (CDC).
The WHO declared the outbreak a Public Health Emergency of International Concern in August 2014. This was the first time that such a declaration had been made for an Ebola outbreak.
The outbreak quickly spread to Liberia and Sierra Leone. The virus was carried by people who had travelled to these countries from Guinea. It then spread through communities via human-to-human contact.
The WHO, MSF and CDC deployed more teams to the affected countries. They were joined by teams from other organizations, including the Red Cross.
The response was hampered by a lack of awareness about the virus and how it spreads. There was also a lack of clinical facilities to treat patients and a lack of trained health workers.
The outbreak had a devastating effect on the countries involved. Over 28,600 people were infected and 11,315 people died. Liberia was the hardest hit, with 10,675 cases and 4,805 deaths. Sierra Leone had 14,124 cases and 3,956 deaths. Guinea had 3,857 cases and 2,554 deaths. Nigeria had 20 cases and 8 deaths.
The health systems in the affected countries were overwhelmed. There were not enough hospital beds, medicines or trained health workers. Families were torn apart as sick relatives were quarantined and died in isolation.
Communities were afraid, leading to widespread panic and mistrust. The economies of the countries affected were also hard hit. The outbreak caused a decrease in trade and a decline in tourism.
The outbreak was finally brought under control in 2016. The last case was reported in Liberia in March 2016. The last case in Sierra Leone was reported in November 2015. The last case in Guinea was reported in December 2015.
The response to the outbreak was hampered by a lack of awareness and a lack of resources. However, it was eventually brought under control through the efforts of the WHO, MSF, CDC and other organizations.
The outbreak had a devastating effect on the countries involved. Over 28,600 people were infected and 11,315 people died. The economies of the countries affected were also hard hit. The outbreak was a tragedy that claimed the lives of too many people and caused untold suffering.Click here to find out more
10 most dangerous computer viruses in the world
Viruses are one of the most common ways that computer users can get malware onto their systems. A virus is a type of malware that can replicate itself and spread to other computers. While there are many different types of viruses, some are more dangerous than others. Here are the 10 most dangerous computer viruses in the world:
1. CryptoLocker
CryptoLocker is a virus that was first seen in 2013. It encrypts files on the infected computer and then demands a ransom be paid in order to decrypt the files. If the ransom is not paid, the files will remain encrypted and inaccessible. CryptoLocker has infected hundreds of thousands of computers and has been responsible for millions of dollars in ransom payments.
2. WannaCry
WannaCry is a ransomware virus that was first seen in May of 2017. It quickly spread across the globe, infecting hundreds of thousands of computers in just a few days. WannaCry encrypts files on the infected computer and then demands a ransom be paid in order to decrypt the files. If the ransom is not paid, the files will remain encrypted and inaccessible. WannaCry was particularly dangerous because it exploited a known vulnerability in Microsoft Windows.
3. Zika
Zika is a virus that is primarily spread by mosquitoes. However, it can also be spread through sexual contact or blood transfusions. Zika can cause severe birth defects in unborn children, including microcephaly, which is a condition where the head is smaller than normal. Zika has spread to many countries in Central and South America, as well as the Caribbean.
4. Ebola
Ebola is a virus that is primarily spread through contact with the bodily fluids of an infected person. It can also be spread through contact with infected animals, such as bats or monkeys. Ebola can cause severe hemorraghic fever, which can lead to death. Ebola outbreaks have occurred in Africa, but the 2014 outbreak was the first to spread outside of Africa.
5. SARS
SARS, or severe acute respiratory syndrome, is a virus that primarily affects the respiratory system. It can cause severe pneumonia, which can be fatal. SARS first emerged in 2002, and primarily affected people in Asia.
6. Swine Flu
Swine flu is a virus that primarily affects pigs, but can also infect humans. Swine flu is similar to the regular flu, but can be more severe. It can cause pneumonia and other serious respiratory illnesses. Swine flu first emerged in 2009, and caused a global pandemic.
7. HIV
HIV, or human immunodeficiency virus, is a virus that attacks the immune system. HIV can lead to AIDS, which is a debilitating and often fatal disease. HIV is spread through sexual contact, blood transfusions, and sharing needles. HIV first emerged in the early 1980s, and has since spread to every corner of the globe.
8. West Nile Virus
West Nile virus is a virus that is primarily spread by mosquitoes. It can cause encephalitis, which is an inflammation of the brain. West Nile virus first emerged in Africa, but has since spread to many other parts of the world.
9. Avian Flu
Avian flu is a virus that primarily affects birds, but can also infect humans. Avian flu is similar to the regular flu, but can be more severe. It can cause pneumonia and other serious respiratory illnesses. Avian flu first emerged in 1997, and has since caused several outbreaks.
10. Norovirus
Norovirus is a virus that causes severe vomiting and diarrhea. It is highly contagious, and can easily spread through contact with an infected person. Norovirus is the most common cause of foodborne illness. It can cause serious dehydration, and can be fatal in young children and the elderly.
