The fifth wave of the covid-19 pandemic in Spain it is drawing a different scenario from the previous waves, thanks to the mass vaccination, which has managed to drastically reduce the number of hospitalizations and deaths caused by SARS-CoV-2 despite a explosive increase in infections, principally among the younger population, which is the one to be vaccinated last because it is the group with the lowest risk of suffering a serious disease.

The characteristics of the fifth wave have led to a increase in asymptomatic positives or with very mild infections whose symptoms are in danger of being mistaken for colds or allergies, as experts warn 20minutos. However, there are also, although fewer, serious cases caused by new variants among the younger population, and proof of this is that the average age of those admitted has been decreasing as vaccination progressed. At the moment, in the Community of Madrid, he is 37 years old. Deaths and ICU admissions, unfortunately, also occur even among the youngest.

For all these reasons and because the pandemic has not yet ended, it is advisable to remain very attentive to the symptoms of covid to isolate yourself as soon as possible and contact the health center.

This fifth wave is characterized by the prevalence of Delta variant, which shares many symptoms with the previous strains, but also has some difference. As recently noted by King’s College London professor Tim Spector, who directs the study of Covid ‘Zoe’ symptoms, getting the Delta variant can manifest itself in a young person “like a bad cold.” This leads to the “problem” that symptoms are underestimated or confused and continue leading a normal life when in fact they are in a period during which they can be contagious and put other people at risk.

As observed by British researchers, the Delta variant most commonly causes the following symptoms:

  • Headache
  • Throat pain
  • Runny nose
  • Fever

In a joint statement, the European Medicines Agency (EMA) and the European Center for Disease Control and Prevention (ECDC) recall that the evidence suggests that the Delta variant, which is between 40% and 60% more transmissible than the Alpha variant (the one originating in the United Kingdom) and than others, it may be associated with a higher risk of hospitalization.

ECDC estimates that by the end of August the Delta variant will account for 90 percent of all SARS-CoV-2 viruses circulating in the European Union. “This makes it essential for countries to accelerate vaccination programs, including the administration of second dose when recommended, and close the immunity gaps and opportunities for greater emergence of variants, as soon as possible, “the statement reads.
