We will never have a normal flu season again.

Experts warn that the COVID-19 pandemic was the harbinger of a new normal in health. The new breed of H3N2 flu (Darwin) came to confirm this assertion, noting that we would no longer have flu “seasons”, with the serious possibility of the coronavirus becoming an endemic disease. And more: Concomitant infection of COVID-19[female[feminine Influenza virus strains seem to be the future trend.

Current vaccination rates demonstrate the effectiveness of vaccination devices, which have reduced hospitalization and death rates from respiratory diseases. However, the discovery of a simultaneous infection with the H3N2 coronavirus, commonly known as covid-19 and H3N2 “Florona”, to alert the scientific community, especially epidemiologists, who fear the double threat.

Experts believe COVID-19 will not be eradicated

There seems to be a consensus among epidemiologists that society will have to learn to live with the coronavirus. A survey of 100 immunologists, virologists and epidemiologists by Nature early last year found that for around 90% of them eradication of the disease is unlikely.

This means it will be endemic disease, which is spreading steadily, but is confined to pockets of the world’s population. The less gloomy aspect of this is that it will be possible to predict its incidence and transmission rates, allowing, for example, to establish vaccination programs at times of greatest incidence, as is already the case in the case of the common flu.

According to Julio Croda, researcher at Fiocruz, serious forms will continue to be controlled. He said in an interview with Newspaper.

Challenges to be met if Covid-19 becomes a major endemic. Vaccination, for example, should become the objective of an annual campaign, vaccines adapting to new variants resulting from the mutation of the virus. Moreover, work and schools will have to adapt to this scenario in which the virus is spreading everywhere.

This information poses a serious challenge to society: to change its behavior in thinking about the collective good. Clusters should be avoided during times of high virus spread, while infected people should stay indoors.

Positive scenarios depend on the coronavirus containment

All the scenarios put forward by the experts are only hypotheses. Some argue that the current dominant form, which is Omicron, is the harbinger of the end of the epidemic. Among the positive scenarios designed, two fill the population with expectations.

At first, the Corona virus will be eliminated in certain regions, as has already happened with other diseases, such as measles. While some parts of the planet enjoy extensive vaccination coverage and epidemiological control, other areas with low vaccination rates will still experience seasonality of the disease, potentially even transmitting it to areas that no longer have of cases. This means that sporadic border closures may occur.

The most positive scenario put forward by the researchers is the complete eradication of the virus. Thus, the immunity acquired by vaccination cannot deteriorate over time and the virus cannot undergo mutations capable of circumventing the protection obtained with vaccines. For this scenario to materialize, it is necessary to complete a vaccination cycle and take booster doses.

The 21st century has already seen three more serious epidemics

In the 21st century alone, three diseases have already shaken the world, affecting large numbers of people, many of them fatal.

  • SARS: Severe acute respiratory syndrome, known as SARS, was also an illness caused by the coronavirus. The first case occurred in 2003, with an outbreak in China, and then spread to neighboring countries. SARS was the first highly contagious disease of the 21st century. Its lethality was 3%, after being controlled by security measures in 2003;
  • H1N1: Like H3N2, H1N1 is caused by a mutation in the flu virus. The outbreak, also known as swine flu, has reached around 75 countries, with Mexico being the first place where the disease was identified. Between 2009 and 2010, more than 650,000 cases and approximately 18,400 deaths were recorded worldwide. Despite its low lethal force, around 0.02%, the H1N1 virus has caused great concern in the population;
  • Ebola: Ebola is not a new virus, with its first cases dating back to 1976 in Sudan and the Democratic Republic of Congo. However, the major Ebola epidemic did not occur until 2013. With more than 28,000 cases identified and 11,000 deaths, the outbreak The Ebola virus epidemic persisted until 2016 in some African countries from West. The death rate is among the highest and most frightening: 90% of people who contract the virus die. In addition, the virus leaves serious sequelae, such as mental health and neurological problems.
