There's no conclusion on the deadliest virus known, but COVID-19 has a lower mortality rate than other viruses throughout history.
For example, AIDS, which is caused by the HIV virus, has a far higher fatality rate. There is no cure for HIV, but it can be managed effectively with medication. While HIV patients can be expected to live long, healthy lives, many countries still do not have access to the treatment needed. According to the U.S government website on HIV, in 2019, there were approximately 38 million HIV/AIDS patients worldwide. Around 690,000 people died from AIDS-related illnesses in 2019, up from 1.1 million in 2010 globally.
In an interview with Radio Free Europe, Peter Lamptey, president of the Family Health International AIDS Institute, said that despite medical advancement, AIDS may overtake the bubonic plague as the most deadly virus in history, as the spread has not been contained in Africa.
Nearly one in every 25 adults within the African region is HIV-positive, accounting for more than two-thirds of the people living with HIV worldwide, WHO reported.
Meanwhile, the bubonic plague is still cited as the most deadly virus in history. The disease is thought to have killed 50 million people in the fourteenth century alone, which is equivalent to 60 percent of Europe's population, according to WHO.
However, it must be noted that it is not possible to categorically state that one virus is the most deadly. Firstly, not all data or recording of deaths is accurate and will vary from country to country. Furthermore, this will depend on the treatment and care available, rather than the unique attributes of a particular disease.
We can conclude that COVID-19 Is not the most deadly virus known to humanity. While data varies, the chances of dying from COVID-19 are thought to be somewhere between 0.5 and one percent. Furthermore, COVID-19 vaccines are expected to be at least 90 percent effective in providing immunization against the virus.
The COVID-19 pandemic has given rise to a lot of potentially dangerous misinformation. For reliable advice on COVID-19, including symptoms, prevention, and available treatment, please refer to the World Health Organization or your national healthcare authority.
