If you're looking for the deadliest viruses in history, you've come to the right place. Below you will find information on the Spanish flu, SARS, HIV, Dengue Virus, and more. You can also learn about the deadly diseases that have infected humans, including the ailment known as Ebola. buckeyehealth All of these viruses have made history, so be sure to read the information about each of them.

Dengue Virus

The dengue virus is a highly contagious tropical disease. Infected mosquitoes transmit the disease. Infected individuals develop a high fever, headache, and muscle and joint pain. Those with severe dengue often suffer hemorrhagic bleeding and even death. yogpower  Fortunately, there are antiviral drugs available that can treat the disease. However, there are no effective vaccines for dengue.

Severe dengue patients enter the critical phase three to seven days after the initial infection. Severe dengue patients may show warning signs such as a deterioration of symptoms and an increase in body temperature. dailywales They may also develop bleeding, plasma leakage, or other abnormalities in the organs. Close monitoring of the patient is essential, and it should continue during the convalescent period.

Currently, there is no vaccine to prevent dengue, but there are several vaccine candidates in development. One is approved for children nine to 16 years of age who have had previous dengue virus infection. The new vaccine is not recommended for travel to endemic areas for travelers living in the U.S. The other two vaccine candidates are currently under study. dave   The vaccine is not recommended for people who have recently been infected with dengue virus.

HIV

Although HIV is one of the most deadly viruses in human history, it can affect anyone. Some groups are at higher risk for infection than others, such as those who engage in homosexual or intravenous drug use, and people who share needles. oguchio HIV is particularly common in Black and Hispanic populations, but is also increasing among transgender people. People with HIV should have regular HIV testing and HIV-related counseling and education.

While the development of a vaccine for HIV is still a few years away, there are already several drugs on the market that can help prevent the virus from spreading. One of these drugs is PEP, which works to stop HIV transmission in the first 72 hours. repdeval  Another example of an antiretroviral medicine is SARS-CoV-2, which causes COVID-19. This virus is spread easily in the community and causes a range of symptoms, including severe abdominal pain and vomiting.

While HIV is a deadly virus that has been killing millions of people for centuries, new antiretroviral medications have made it manageable for most people. The goal of the antiretroviral therapy for HIV is to get the virus levels down to undetectable levels. feurio While it is still a chronic illness, most people with HIV are younger than 50 years old. If you are under the age of 20, you should get tested to make sure that you are HIV-free.

SARS

As of June 2010, SARS has killed more than 4,000 people around the world, a death rate that is still among the highest in the history of mankind. The virus's evolutionary traits, combined with its high mortality rate, contributed to the rapid eradication of the disease. In addition to being highly contagious, the virus spreads through droplets that people exhale while breathing, making it difficult to avoid contact with infected people.  camp In fact, experts believe that the spread of Sars could have caused devastation on a scale similar to the HIV crisis, or to the 1918 influenza pandemic, which killed fifty million people.

Until recently, scientists were unclear how SARS could enter the body, but recent research has shown that SARS-CoV-2 has a unique ability to get inside the respiratory system and cause fatalities. omwhealthit  Its proteins attach to a receptor known as ACE2, which is highly expressed on the lining of veins and arteries. It is particularly dense on cells lining the small intestines and alveoli.

Spanish flu

There have been countless influenza outbreaks, but none have been quite as destructive as the Spanish flu pandemic of 1918-19. It is one of the deadliest viruses in history and was the first to make millions of people seriously ill. salon As a result, Spanish flu is often called the "forgotten pandemic" and has been memorialized as one of the most deadly in the history of medicine.

The 1918 Spanish flu pandemic was one of the deadliest in history, but a recent theory suggests it might have originated in China. It was brought over by Chinese farm workers to the Western Front during the war, where they spent six days in train containers. blogforphotos They were needed to help build roads, dig trenches, and unload trains. They also repaired damaged tanks. A new study suggests that over 90,000 Chinese laborers were mobilized to help on the Western Front.

Initially, it was thought that Spanish flu was a mild epidemic, which killed a small group of people. However, the outbreak spread rapidly to cities and main transportation routes, resulting in a major epidemic. ugg  During the first wave, there were only three deaths in Madrid, but by the second, more than 100,000 people had been infected. By March 1919, the disease had spread to the entire continent and most theaters and saloons were closed.

Lassa virus

The Lassa fever is an acute viral haemorrhagic illness caused by the Lassa virus. This zoonotic disease affects many countries in West Africa, but is most common in Sierra Leone, Liberia, Guinea, and Nigeria. It is usually spread by a rat, the Mastomys natalensis. walkinginthedesert The virus is endemic in the area, but can also spread to neighboring countries.

Symptoms of Lassa fever can be attributed to the fact that the Lassa virus can be spread by blood, tissue, excretions, or sexual transmission. Patients can contract Lassa fever if they are infected by an infected person or infected by contaminated needles. Lassa fever can be fatal if it isn't treated in time, so a vaccine is needed as soon as possible. www  Currently, there is no approved vaccine for Lassa fever, but various experimental vaccines are being developed. But none of them have passed FDA trials.

Small rodents like mice and rats can easily make their way into homes and other public places. This is why the outbreak in Lassa, Nigeria, was so high in recent years. Despite the disease's low profile, it is still fatal to humans. rjgg The disease is often fatal in people living in rural areas, and it is especially common in health care settings, where inadequate infection control is lacking.

Rotavirus

The rotavirus is a double-stranded RNA virus from the family Reoviridae. The virus infects humans and livestock and is the leading cause of diarrhea in children. When it enters the body, it damages the lining of the small intestine, causing gastroenteritis. philippesenderos Each year, around 215,000 children die as a result of this infection. The most common areas infected with the rotavirus are the Third World.

There are two vaccines for the rotavirus, Rotarix and RotaTeq. Rotarix is given in two doses, at age 2 months and at 4 months. Although both vaccines are relatively safe, there is a small risk of intussusception, a rare condition that can occur after the vaccine. michaelkorsaustralia However, these vaccines prevent the most common and potentially fatal cases of the disease, and are part of the routine immunization schedule for infants.

Another virus that can be highly lethal is the Lassa Virus. The Lassa Virus was first discovered in Nigeria in 1969. A missionary nurse named Laura Wine and her nursing colleague Lily Pinneo contracted the mysterious illness. The samples of the virus were sent to Yale University for analysis. Researchers found that the virus was originally derived from common African rats, but that it can also be transferred from human to human through broken skin or semen.

COVID-19

Viruses are known to be deadly for the humans that they infect, and the latest outbreak of COVID-19 is the deadliest in recent American history. articleconsortium Already, the death toll has surpassed the estimated fatalities of the 1918 influenza pandemic. As of Monday, more than 675,000 cases of the virus have been confirmed in the U.S., a figure which continues to rise. A fast-spreading delta variant of the virus is responsible for this epidemic's rapid spread.

In early April 2020, an unusual outbreak of pneumonia in China raised the death toll to 80,000. Today, the official COVID-19 death toll is five million, a figure which is widely considered an underestimate. Most credible analyses peg the death toll of SARS-CoV-2 at closer to 17 million. angelicaliddelDespite the staggering death toll, many survivors are still suffering from persistent symptoms.

This pandemic is the third coronavirus pandemic recorded. The SARS-CoV-1 and MERS-CoV epidemics followed in the late 1990s and early 2000s, but they did not reach the global scale of COVID-19. The two previous epidemics did not reach this level, but their case fatalities were significantly higher than COVID-19's.
