Researchers from the Penn State University, in the US, in a fresh study explored what the Coronavirus (COVID-19) infections will look like for consumers in the coming years.

The researchers鈥� findings suggest that kids may become the most at-risk demographic for contracting the virus over the next decade as adult exposure and vaccinations increase.

The researchers predict that COVID-19 could become an infection similar to the common cold and will likely peak during certain seasons.

Ottar Bjornstad, one of the researchers, said: 鈥淔ollowing infection by SARS-CoV-2, there has been a clear signature of increasingly severe outcomes and fatality with age.

鈥淵et, our modelling results suggest that the risk of infection will likely shift to younger children as the adult community becomes immune either through vaccination or exposure to the virus.鈥�

The expert also stated: 鈥淗istorical records of respiratory diseases indicate that age-incidence patterns during virgin epidemics can be very different from endemic circulation.

鈥淔or example, ongoing genomic work suggests that the 1889-1890 pandemic, sometimes known as the Asiatic or Russian flu, which killed one million people, primarily adults over age 70, may have been caused by the emergence of HCoV-OC43 virus, which is now an endemic, mild repeat-infecting cold virus affecting mostly children ages 7-12 months old.鈥�

As regards determining what the future may look like for the study, the researchers developed a 鈥渞ealistic age-structured (RAS) mathematical model鈥� to determine what COVID-19 infections may look like as the virus becomes endemic.

They also examined factors, such as duration of disease-reducing immunity, demographics, and socialising patterns.

The researchers focused on what these outcomes will look like over 1, 10, and 20 years in 11 different countries, including the US, China, Italy and Spain as well.

Ultimately, the model indicated that children are more likely than adults to be infected by the coronavirus over the next decade.

Researcher Ruiyun Li also stated: 鈥淔or many infections and respiratory diseases, prevalence in the population surges during a virgin epidemic but then recedes in a diminishing wave pattern as the spread of the infection unfolds over time toward an endemic equilibrium.

鈥淒epending on immunity and demography, our RAS model supports this observed trajectory; it predicts a strikingly different age structure at the start of the COVID-19 epidemic compared to the eventual endemic situation.

鈥淚n a scenario of long-lasting immunity, either permanent or at least 10 years, the young are predicted to have the highest rates of infection as older individuals are protected from new infections by prior infection.鈥�

Planning for what鈥檚 ahead

The researchers explained that their predictions depend on how consumers鈥� bodies respond to reinfection; as long as re-exposure leads to mild infections, the virus shouldn鈥檛 pose a significant threat to adults鈥� health long term.

Going forward, the research team hopes that this model can be helpful for countries making important public health decisions.

鈥淭he mathematical framework we built is flexible, and can help in tailoring mitigation strategies for countries worldwide with varying demographics and social mixing patterns, thus providing a critical tool for policy decision making,鈥� said Bjornstad.
