Several pharmaceutical companies have developed innovative mRNA vaccines to counter the coronavirus. However, it has been suggested that the virus may have originated from a virus research lab in Wuhan. Initially, it was accepted that the coronavirus originated in a wet market in Wuhan, China, within bats sold as food. There is an ongoing debate as to the origin of the coronavirus. Critics assert that coronavirus passports represent an extreme violation of liberties. Perhaps most controversial were the introduction of coronavirus passports, which would allow vaccinated citizens to move freely with a new form of ID. Early in the pandemic, lockdowns were used to prevent interaction between the public, in a severe attempt to halt transmission. Social distancing and mask mandates have also become popular in many countries to prevent spread of infection. Contact tracing has become the norm, with citizens being obligated to quarantine after they have come into contact with an infected person. Many countries have severely restricted flights or entry into their state, with some like Israel adopting color systems to rank the risk posed by each destination. In response to the coronavirus pandemic, governments have initiated several policies to prevent spread. In severe cases, patients undergo respiratory distress and require intubation on ventilators. Senior citizens are most at risk of dying from the disease, though secondary pre-existing conditions like obesity can make some patients more susceptible to danger. Symptoms of infection include fever, joint and muscle aches, respiratory distress, loss of the sense of taste, cognitive fog, fatigue, sore throat, and more.

The 2019 coronavirus (COVID-19) pandemic, caused by the SARS-CoV-2 novel virus, originated in Wuhan, China before rapidly spreading around the world.Д¬OVID-19 is a highly infectious respiratory disease, with a high rate of transmissibility.
