The new COVID-19 XEC strain, a highly transmissible variant of Omicron, has spread to 27 countries and could soon affect Nigeria. Experts warn that even vaccinated individuals are at risk of reinfection. Nigerian authorities urge continued vigilance, mask-wearing, and vaccination to reduce transmission.
The fight against COVID-19 continues to face new challenges with the emergence of evolving variants of the virus. The latest variant, known as XEC, was first detected in Germany in June 2024 and has since spread to 27 countries across Europe, North America, and Asia. Over 600 cases have been reported in recent months. Although this strain has not yet appeared in Nigeria, health authorities are monitoring the situation closely and urging the public to remain alert and proactive in their efforts to prevent its spread.
Key Characteristics of the XEC Strain
The World Health Organization (WHO) has confirmed that the XEC strain is a subvariant of the Omicron lineage of the SARS-CoV-2 virus. Like its predecessors, the XEC strain is highly transmissible and can partially evade the immune defenses provided by past infections or vaccines. This means that even individuals who have been previously infected or vaccinated may still be at risk of reinfection. However, vaccines remain the most effective defense against severe illness.
Spread and Impact
Countries such as the United States, the United Kingdom, Canada, and China have reported cases of the XEC strain, with rising infection rates linked to its increased transmissibility. Data from the UK Health Security Agency (UKHSA) shows that the strain has been causing a noticeable uptick in hospital admissions in affected regions. The strain is a combination of two variants, KS.1.1 and KP.3.3, and experts suggest that it could spread more rapidly due to its mutations.
Symptoms and Severity
The symptoms of the XEC strain mirror those of other COVID-19 variants and include fever, fatigue, sore throat, shortness of breath, headaches, and loss of taste or smell. The elderly and those with underlying health conditions are particularly at risk of experiencing severe complications. Health officials recommend continuing preventive measures such as mask-wearing and social distancing to reduce the risk of transmission.
Nigeria's Response
In Nigeria, while the XEC strain has not yet been officially detected, experts are urging the public to remain cautious. The Nigerian Ministry of Health, led by Prof. Muhammad Ali Pate, is closely monitoring the global spread of the strain and is advising healthcare providers to stay prepared for its potential arrival. Nigerians are encouraged to continue adhering to safety protocols and to get vaccinated at designated public health centers.
Public health experts like Dr. Adesola Adebayo emphasize the importance of following COVID-19 safety measures, including wearing masks, practicing good hygiene, and ensuring vaccination. The National Primary Health Care Development Agency (NPHCDA) has made vaccines available in public health centers, malls, event centers, and schools across Nigeria.
Ongoing Vigilance and Protection
The emergence of the XEC strain is a stark reminder that the fight against COVID-19 is far from over. Nigerians must remain informed, follow public health guidelines, and get vaccinated to protect themselves and their communities from this evolving threat.
