Resurgent variants

While China is currently facing a serious health crisis due to the spread of the new omicron variant called Omicron BF.7 the world is shaken by the fact that the new virus is highly infectious and which has raised questions about the efficacy of covid vaccines. It is a brand-new coronavirus mutant with a short incubation period and a quick rate of transmission to other people. With one of the highest transmissibilities among all Covid variants, the variant is an Omicron mutant. However, there are pros and cons regarding vaccines and their efficacy. The general belief among health officials is that unvaccinated individuals are more at danger. The chance of contracting this infection is also increased in those with weakened immune systems, including as children, the elderly, pregnant women, and persons with numerous comorbidities, such as uncontrolled diabetes, cancer, kidney, or heart disease. As a precautionary measure, people should adhere to Covid-appropriate behaviour and get vaccinated for Covid-19. It is pertinent to note that after the first and second covid pandemic wave during 2020 and 2021 the Delta variant had inflicted terrible tragedies across India. According to reports, BF.7 is causing the present COVID situation in China. It is anticipated that approximately 60% of China and 10% of the global population are expected to contract the disease in the ensuing three months, with millions of deaths. According to numerous assessments, the Chinese still have a low immunisation rate as compared to India and also make insufficient investments in emergency care. India witnessed the first wave in 2020 caused by SARS-Cov-2 virus followed by a more potent and deadlier Delta variant. The second and deadlier wave gradually ebbed by the end of 2021 and by 2022 number of infections drastically came down from lakhs to thousands and four digits. The Covid-19 trajectory in India experienced a sharp increase during March-May 2021, however, since May 2021, the trajectory has witnessed a considerable and sustained decline. As the year 2022 went by, it was also a reminder that India has not only the threat of Covid infection, but today, also of other viruses. As of January 4, 2023, official sources inform that India has the second-highest number of confirmed cases in the world (after the United States of America) with 44,680,355 reported cases of COVID-19 infection and the third-highest number of COVID-19 deaths (after the United States and Brazil) at 530,707deaths. Covid-19 until the year 2022 comes in ten different variations, the most recent being BF.7. The danger of contracting this virus is higher in those who are unvaccinated or have weakened immune systems, such as the elderly and young children. The ability of the virus to evade neutralising antibodies produced by vaccinations or prior infections has been connected to this mutation. The subvariant does have a higher potential for re-infection or for infecting people who have already had a vaccination, according to experts. A recent study also revealed that BF.7 could evade protection even in the case of patients who had already received three vaccinations. Testing will remain as the only way to determine the spread of the virus and therefore, it means Covid Appropriate Behaviour is back.
