And the WHO recommends that people stay at least 6 ft from anyone coughing or sneezing to help prevent the transmission of the SARS-CoV-2 infection. Tiny droplets containing the viruses can pass from someone with the infection to someone else, typically through the nose and mouth via coughing and sneezing.Īccording to the CDC, people can transmit the flu virus to others who are 6 feet (ft) away. We are still learning about post-COVID conditions, also known as long COVID, that may result from infection with the new coronavirus.Ĭompared with the flu, research on COVID-19 remains in its early stages.Īccording to the CDC, getting vaccinated for COVID-19 and following recommended booster schedules is the best way to prevent severe illness.īoth SARS-CoV-2 and the flu virus primarily spread through person-to-person contact. Those most at risk of severe illness or complications related to these viruses include the elderly and those with underlying medical issues. According to the WHO, the mortality rate for COVID-19 appears to be higher than that of the flu. ![]() The chance of severe and critical infection is higher with COVID-19 than with the flu.ĬOVID-19 is also more deadly. However, according to July 2022 data from the Centers for Disease Control and Prevention (CDC), about 9% of COVID-19 cases were severe enough to require ICU care, and about 0.6% needed mechanical ventilation. People in a critical state require a ventilator to breathe. Initial data from the World Health Organization (WHO) suggested that 15% of COVID-19 cases are severe, and 5% are critical. However, most cases of both the flu and COVID-19 are mild and can be treated and managed at home. “By studying their immune response, this might enable us to identify new ways of promoting immune protection against Sars-CoV-2 that could be used in future development of vaccine or drugs,” said Prof Stephanie Gras, laboratory head at La Trobe University, which carried out the immune system experiments.The symptoms of COVID-19 and flu can range from mild to severe. Scientists are now hopeful that the finding could help create new drugs or vaccines that induce the same immune effect. Those who carried two copies of the variant were more than eight times more likely to avoid feeling sick.įurther analysis by La Trobe University, Melbourne, Australia, found that immune cells of people with the mutation responded to part of the Covid-19 called the NQK-Q8 peptide – which is very similar to the NQK-A8 peptide carried by cold viruses. Of those, 136 individuals remained asymptomatic for at least two weeks before and after testing positive. They identified 1,428 unvaccinated donors who tested positive between February 2020 and the end of April 2021, before the vaccines were widely available. The mutation is thought to be carried by around 10 per cent of the population, which roughly corresponds to the number of people who never reported a Covid infection.Īlthough it does not prevent the virus from infecting cells, it stops symptoms – so many people would have not realised they had an infection.įor the study, researchers cross-referenced data from the US Covid-19 Citizen Science Study and US bone marrow registry to find people who were infected with and without symptoms, and checked to see if they carried different genes. It could open the door for new ways of preventing an infection. The research, published in the journal Nature, is the first evidence that there is a genetic basis for why some people never become sick from Covid-19. ![]() “It’s like having soldiers that are prepared for battle and already know what to look for, and that these are the bad guys.” “If you have an army that’s able to recognise the enemy early, that’s a huge advantage,” said Prof Jill Hollenbach, the study’s lead researcher. ‘Like having soldiers prepared for battle’ The mutation helped immune cells recognise Covid-19 even though they had never encountered it before, thanks to its resemblance to the seasonal cold viruses. The gene mutations identified code for human leukocyte antigen (HLA), a protein marker that flags up threats to the immune system. It suggests their bodies were better at recognising Covid-19 as an invader and flushing it from their systems before it could cause complications. Scientists at the University of California discovered that people carrying certain immune system gene mutations were up to eight times less likely to report symptoms, even if they were infected. Covid “super-dodgers” who never became sick from the virus were protected because their immune system treated coronavirus like the common cold, a new study suggests. ![]()
