The last known subvariant of Omicron that has a higher incidence of COVID-19 infections His sea monster nickname is Kraken, although his technical name is XBB 1.5. It is the most contagious of all known, Kraken comes from Scandinavian mythology, and refers to a giant squid, which appeared in the movie ‘Pirates of the Caribbean’ as the ‘pet’ of Davy Jones, the dreaded captain of the ‘Flying Dutchman’. In medicine, it is the cause of the largest wave of infections of the above disease in the past two years, and it was detected in the United States last October. as well It has notably appeared in 30 other countries around the world, and has been detected in many more countries. Specifically, the variant has been detected in European countries such as Germany, Austria, Belgium, the Czech Republic, Denmark, Slovenia, Spain, France, Ireland, Iceland, Italy, the Netherlands, Portugal, Romania, and Sweden.
The World Health Organization (WHO) has clarified that the symptoms are similar to those of the common cold with other Omicron subvariants, and that infections are not severe in a high percentage. XBB 1.5 is an evolution of XBB, which was discovered in the United Kingdom in September last year. What worries experts is the F486P mutation of the so-called Kraken, which restores the human body’s defenses and ability to infect cells.
Currently, the percentage of COVID-19 cases in the United States caused by XBB 1.5 is 40%: It is the leading cause now, when a month ago it accounted for only 4% of cases. For this reason there has also been an increase in the number of hospitalizations, especially among the most vulnerable due to age or previous conditions, especially those related to low immunity.
Last Friday, January 6, the United States Food and Drug Administration (FDA) reported that the XBB.1.5 variant of the coronavirus is likely to be resistant to the drug ‘Evushheld’ against COVID-19, which was marketed by the British laboratory. AstraZeneca. It was the last antibody of its class still licensed in the United States to prevent infection in high-risk people.Since the rest of the drugs were rejected because of the high probability that they did not protect against new forms.
Characteristics of XBB 1.5

- sore throat.
- Excessive fatigue.
- Runny and stuffy nose.
- Headache and joint.
- Premature loss of taste and smell.
Kovid infection in the month of February
The European Center for Disease Control and Prevention (ECDC) does not expect the XBB.1.5 subvariant to increase COVID-19 cases in Europe in the month of February, as it is currently “at a very low level.” “There is a risk that this variant could have an increasing effect on the number of COVID-19 cases in the EU, but not over the next month, as the variant is currently present only at very low levels.“, highlighted the European body through a statement.
This Monday, January 9, the Ministry of Health updated the epidemiological situation of the SARS-CoV-2 variant in Spain. The report highlights that Lineage XBB.1.5, the percentage of which has shown an increase in recent weeks in the United States (it would have exceeded 25% in the first week of January), has been detected in a timely manner in Spain to date, The recombinant lineage XBB was designated as a variant of interest on 8 December.
The Microbiology and Infectious Diseases Service of the Gregorio Maranon Hospital has detected it on Tuesday First case in the Community of Madrid of the XBB1.5 variant of Covid, This is a 63-year-old man with flu-like symptoms for five days, who has been given three doses of the vaccine against COVID-19 and no travel history, who is progressing well and does not require admission .
