Covid-19 cases on the rise: Is the world facing a new wave?

The Covid-19 pandemic’s public health emergency was declared over by the WHO on May 5, 2023, however the virus is still active. And it has no plans to stop anytime soon. As a result, it was normal to anticipate an increase in infections like those that have been seen recently in Spain and other regions of the world. The records are no longer as thorough as they were during the first two years of the global epidemic, and the peaks and troughs in transmission have not been tracked since the summer of 2022, following the seventh wave.

There are no signs that the most recent spike, which began at the end of June, is more severe than earlier ones, but it has already surpassed the incidence rate of the upward tick in December of last year.

By March 2022, Spain stopped measuring instances in the general population and limited follow-up to people over 60. And since July 2023, when the government declared the health emergency over (two months later than the WHO), it has ceased publishing reports on all cases that have been identified in favor of using the same approach that has been used for influenza for a long time, which is based on an estimate created using information provided by health centers and hospitals.

The most current one indicates an incidence slightly higher than the peak of last December, at 137.3 instances per 100,000 people. The highest rates have been seen in persons over 64 and youngsters under four.

Due of enduring protection from earlier vaccines and infections, Covid-19 hospitalizations in the U.S. have been growing since late summer but not nearly as much as at this time last year. However, the most recent WHO report, dated August 10, notes that Johns Hopkins University, one of the international benchmarks for Covid-19 statistics, discontinued reporting in March 2023.

“Over 2,500 deaths and nearly 1.5 million new cases of Covid-19 were reported worldwide in the last 28 days (10 July to 6 August 2023), representing an increase of 80% and a decrease of 57%, respectively, compared to the prior 28 days.”

According to the European Centre for Disease Prevention and Control, the XBB family of variations continue to be the most common in Europe. The reason that viral mutations persist is because they are more contagious than earlier strains, yet no new mutations have been found to be more harmful than the ones that came before them. Due to a combination of innate and vaccine-induced immunity, it is increasingly common for infections to spread among people with minimal or no symptoms. The WHO has identified two variants of interest: EG.5, also from the XBB family and a sub-lineage of Omicron, and BA.2.86, also known as Pirola, which was initially discovered in Denmark in July and has since spread to the UK and the United States, among other nations. None of these strains have been shown to produce more severe symptoms or to be more resistant to vaccination than any of its forerunners, according to a statement made by the Pan American Health Organization in August.

Fewer travel restrictions are in place presently due to the lifting of Covid-19 restrictions worldwide. No longer required are a Covid-19 test result or immunization documentation for visitors to the United States. In the EU, the majority of limitations on non-essential travel were lifted in March 2022, and isolation from those who are ill is no longer required. Now, the advice is the same as it would be for any other respiratory infection: if symptoms worsen, consult a doctor, and have him or her sign the patient off work if required. However, experts advise wearing a mask to lessen the risk to others and teleworking as much as possible in the event of a favorable outcome.

This is crucial when dealing with those who are more prone to serious sickness, such as the elderly (particularly those over 80), or people with underlying conditions. Since they are the ones who are most at risk of being admitted to the hospital for covid, these population groups should also be extra cautious when interacting with one another now that cases are on the rise.

In October, there will be a fresh immunization drive. The Pfizer medication, tailored to the variations of the XBB family, has already received approval from the European Medicines Agency and is anticipated to be the most extensively used, assuming that the doses come on schedule. Updated Covid-19 vaccines have been approved in the United States by the Food and Drug Administration (FDA), and the most recent shots from Moderna and Pfizer and its partner BioNTech will be made available to most Americans even if they have never received a coronavirus immunization. On Tuesday, a Centers for Disease Control advisory panel is expected to provide recommendations for who needs the revised vaccinations the most. The Covid-19 and flu shots can both be administered at the same appointment, and vaccinations might start later this week.
