Wuhan Virus Outbreak! What is Wuhan Virus And 5 Deadliest Virus In The World

Hello everyone,Welcome to my channel, I’m Annabelle. Today I would like a talk about virus Before i start,there a mysterious virus or called Wuhan virus been found in 31/12/2019 What is Wuhan virus and what is the symptoms? For more information about it,please stay tune until the end. Ebola virus disease (EVD) is a deadly disease with occasional outbreaks that occur primarily on the African continent EVD most commonly affects people and nonhuman primates (such as monkeys, gorillas, and chimpanzees) It is caused by an infection with a group of viruses within the genus Ebola virus. only four (Ebola, Sudan, Taï Forest, and Bundibugyo viruses) are known to cause disease in people. Reston virus is known to cause disease in nonhuman primates and pigs, but not in people It is unknown if Bombali virus, which was recently identified in bats, causes disease in either animals or people Ebola virus was first discovered in 1976 near the Ebola River in what is now the Democratic Republic of Congo Since then, the virus has been infecting people from time to time, leading to outbreaks in several African countries. Scientists do not know where Ebola virus comes from However, based on the nature of similar viruses, they believe the virus is animal-borne, with bats or nonhuman primates with bats or nonhuman primates being the most likely source Infected animals carrying the virus can transmit it to other animals, like apes, monkeys, duikers and humans. The virus spreads to people initially through direct contact with the blood, body fluids and tissues of animals Ebola virus then spreads to other people through direct contact with body fluids of a person who is sick with or has died from EVD This can occur when a person touches
these infected body fluids (or objects that are contaminated with them), and the virus gets in through broken skin or mucous membranes in the eyes, nose, or mouth People can get the virus through sexual contact with someone who is sick with EVD, and also after recovery from EVD The virus can persist in certain body fluids, like semen, after recovery from the illness Ebola survivors may experience side effects after their recovery, such as tiredness, muscle aches, eye and vision problems and stomach pain the history of SARS was short but not so
sweet SARS generated widespread panic in 2003 and was caused by a previously unknown coronavirus (SARS-CoV) – the same family of viruses that causes a cold Symptoms began two to ten days after coming into contact with the virus and included a high fever, headache, body aches, sometimes diarrhea. But the main symptom of concern was the severe breathing difficulties associated with SARS, and almost all those infected developed pneumonia By the end of 2003, 774 people had died out of the 8,098 infected people notified to WHO Many more people needed to be hospitalized for breathing assistance SARS is spread through close contact with infectious droplets released during a cough or sneeze SARS started in Asia, and researchers have identified the most likely source as wild Chinese Horseshoe bats that had been caught and brought to market These bats harbored a SARS-like virus that subsequently infected civets before mutating; which meant that humans were now susceptible to the virus Within a year, the infection had spread to more than two dozen countries before it was contained through public health measures The Black Death ravaged most of Europe and the Mediterranean from year 1346 until 1353 Over 50 million people died, more than 60% of Europe’s entire population at the time Many historians believe it started in the Steppes of Central Asia, a vast area of grassland that even today still supports one of the world’s biggest plague reservoirs an area where rodents live in great numbers and density (also called a plague focus) Plague is mainly spread through the bite of a flea infected with the plague-causing
bacterium, Yersinia pestis Fleas typically live on small animals such as rats, gerbils, marmots and squirrels and periodically, explosive outbreaks of plague occur among these susceptible
hosts Huge numbers of animals succumb to infection and die Hungry fleas turn to humans and within three to five days of a bite, fever, headache, chills, and weakness develop Lymph nodes closest to the bite site swell to form a painful bubo in the variant of plague known as bubonic plague infection may spread throughout the blood stream and affect respiration in the lungs. Without prompt antibiotic treatment, 80% of infected people die within five days. HIV (human immunodeficiency virus) is a virus that attacks cells that help the body fight infection, making a person more vulnerable to other infections and diseases It is spread by contact with certain bodily fluids of a person with HIV most commonly during unprotected sex
(sex without a condom or HIV medicine to prevent or treat HIV), or through sharing injection drug equipment If left untreated, HIV can lead to the disease AIDS However, by taking HIV medicine (called antiretroviral therapy or ART), people with HIV can live long and healthy lives and prevent transmitting HIV to their sexual partners In addition, there are effective methods to prevent getting HIV through sex or drug use, including pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) First identified in 1981, HIV is the cause of one of humanity’s deadliest and most persistent epidemics The 1918 influenza pandemic was the most severe pandemic in recent history It was caused by an H1N1 virus with genes of avian origin Although there is not universal consensus regarding where the virus originated, it spread worldwide during 1918-1919 In the United States, it was first identified in military personnel in spring 1918 It is estimated that about 500 million people or one-third of the world’s population became infected with this virus The number of deaths was estimated to be at least 50 million worldwide with about 675,000 occurring in the United States. Mortality was high in people younger than 5 years old, 20-40 years old, and 65 years and older The high mortality in healthy people, including those in the 20-40 year age group, was a unique feature of this pandemic While the 1918 H1N1 virus has been synthesized and evaluated, the properties that made it so devastating are not well understood With no vaccine to protect against influenza infection and no antibiotics to treat secondary bacterial infections
that can be associated with influenza infections control efforts worldwide were limited
to non-pharmaceutical interventions such as isolation, quarantine, good personal hygiene, use of disinfectants, and limitations of public gatherings, which were applied unevenly A mysterious virus or called Wuhan virus has caused an international outbreak of respiratory illness in 31 dec 2019 This virus can make people sick, usually with a mild to moderate upper respiratory tract illness, similar to a common cold The symptoms include a runny nose, cough,sore throat, possibly a headache and maybe a fever, which can last for a couple of days Wuhan virus originated in the central Chinese city of Wuhan and has been linked to Wuhan’s Huanan Wholesale Seafood Market, which has since been closed The virus quickly spread throughout China other countries in Asia The number of human infections has grown dramatically, to more than 500 in China, and cases have now been confirmed in Taiwan, Japan, Thailand and South Korea At least 17 people confirmed died.
