In recent weeks, India has witnessed a sudden spike in daily COVID-19 cases, prompting several states including Delhi, Maharashtra, Kerala, and Karnataka to be placed on high alert. While the JN.1 variant remains the dominant strain across Asia, health experts have raised concerns about the emergence of two additional sub-variants: NB.1.8.1 and NF.7. These potentially more transmissible strains have been linked to the recent surge in cases reported in regions such as Delhi-NCR, Andhra Pradesh, Telangana, and Bengaluru.

The World Health Organization (WHO) has declared that these variants are being closely monitored, and no other alarming advisories, serious revelations or warnings have been raised so far.

The symptoms of COVID are extremely contagious, which means there is an enhanced possibility of one infected person spreading the infection to others, but what makes it even worse is the difficulty in identifying its indicators, as they are highly ambiguous and often confused or linked with other diseases. The health officials, despite the stable condition, have asked the people to look out for certain symptoms before getting them checked or tested.

New COVID Symptoms You Should Know

Symptoms of the NB.1.8.1 to look out for:

  1. Sore Throat: facing difficulties in swallowing food or drinking water. Feeling strain on the throat while talking.
  2. Extreme Fatigue: Running low on energy and not being able to do the bare minimum or a monotonous task. This makes one feel deprived of energy and makes them slow and lethargic.
  3. Mild Cough: Cough is another major symptom of the infection, which might cause discomfort in the chest.
  4. Fever And Muscle Ache: A rise in body temperatures is noted in the patients infected with the variant. This is also accompanied by severe to mild muscle aches. Feeling stiffness in the muscles or even a sort of tightness that feels like putting extra strain on them while doing the quotidian tasks.
  5. Nasal Congestion: having a choked nasal passage and difficulty breathing through the nose are some indications.
  6. Low-Grade Hyperthermia: Low-grade hyperthermia, which can be a condition of low-grade fever, is a slight increase in body temperature, typically between 99.1 F to 100.4 F (37.3 C to 38.0 C). It's generally not a cause for instant concern, but it can indicate that the body's infected by the virus and the immune system is working to fight off the virus infection.
  7. Headaches: Heaviness in the head or restlessness can be clear indicators, often leading to distraction and loss of focus.
  8. Nausea or Vomiting: feeling dizzy or having the urge to vomit are visible symptoms of the viral infection.
  9. Gastrointestinal Issues: Several gastrointestinal problems that might cause digestive issues or loss of appetite, are clear signs.

It must be noted that these symptoms are more common and prevalent in busy metropolises. The giant population is often linked to the quick spread of infection; the people who are not vaccinated are known to be more prone to developing the infection after being attacked by the virus. The efficacy of the symptoms varies in every patient from mild to moderate, considering the parallel factors like immune power and prior history of vaccination.

The virus is being closely monitored and no serious spike has been noticed as of now, the hospitalization rate too remains under control. However, the people are advised by the health officials to follow the necessary precautions and protocols like using sanitizers or masks and to avoid any large public gatherings that can cause a mass level spread of infection.
