The World Health Organization (WHO) has raised concern over a new strain of the COVID-19 virus, warning that global infections are on the rise once again. The newly identified variant, NB.1.8.1, has been designated a “variant under monitoring” due to its growing global presence and rapid transmission capabilities.
In a recent alert, WHO revealed that most cases linked to NB.1.8.1 have been reported in the Eastern Mediterranean, Southeast Asia, and Western Pacific regions. Experts caution that this variant could be more transmissible than previous strains and is already responsible for over 10% of COVID-19 cases globally.
The new variant presents symptoms that are largely consistent with previous iterations of the virus. These include sore throat, fatigue, fever, mild cough, muscle aches, and nasal congestion. In some cases, individuals may also experience gastrointestinal symptoms such as nausea or diarrhea.
While there is currently no evidence that NB.1.8.1 causes more severe illness, the WHO is urging member states to remain alert and responsive. “Member States should continue offering COVID-19 vaccines in line with WHO recommendations,” the agency stated, emphasizing that vaccination remains a critical tool in managing the virus’s spread and impact.
The WHO further advised countries to adjust their COVID-19 strategies based on evolving epidemiological trends. This includes ramping up surveillance, strengthening health systems, and integrating COVID-19 management with broader respiratory disease preparedness plans.
This development comes as many countries had relaxed COVID-19 protocols and reduced public health interventions. With the emergence of NB.1.8.1, experts warn that complacency could lead to another wave of infections, particularly in areas with low vaccination coverage or limited healthcare infrastructure.
Citizens are advised to practice good hygiene, wear masks in crowded indoor spaces, and stay informed through official health channels. The resurgence of COVID-19, driven by this new variant, underscores the need for ongoing vigilance, international cooperation, and public awareness as the world continues to navigate the evolving challenges of the pandemic.
