Covid cases have surged in recent weeks in Delhi, Uttar Pradesh, Rajasthan and Bihar, due to temperature fluctuations and the emergence of newer, more contagious strains, experts say. Delhi has reported 63 new Covid cases in the last 24 hours, while other cases in northern states such as Rajasthan, Uttar Pradesh and Bihar are also seeing a slight uptick. Delhi last reported these figures in May last year. In the past 15 days, Delhi has recorded 459 Covid cases, up from 191 in the last fortnight and 73 in the last 15.

The recent surge in Covid-19 cases in northern India, which encompasses states such as Delhi, Rajasthan, Uttar Pradesh and Bihar, has raised concerns and this can simply be attributed to a combination of key issues ranging from low testing rates to the emergence of mutant variants. Fluctuating climatic situations in northern India.
Dr. H Guru Prasad, Associate Clinical Director and Head of the Department of Internal Medicine at CARE Hospitals, Banjara Hills, Hyderabad, in an interview with HT Digital, explains the conceivable reasons for the Covid surge in North India.
Dr. Prasad says that the new mutants are possibly more transmissible than the previous ones and that there is also an upward trend in cases expressed in the region. While North India is seeing a sharp rise lately, cases are declining in South India.
“The recent accumulation of Covid-19 cases in northern India is influenced by a combination of factors, including the emergence of mutant variants, low testing rates, past waves, regional diversifications, and the effect of weather conditions. Remaining vigilant and following preventive measures, in addition to vaccination, remains very important to mitigate the spread of the virus,” he says.
• Emergence of mutant variants: The accumulation of infections is related to the emergence of highly transmissible mutant variants, adding Omicron XE and BA. 2, which particularly contributes to the existing spike³.
• Testing rates and actual numbers: Low testing rates suggest that the actual number of cases is likely much higher, as the reported numbers fully reflect the true scale of infections.
• Previous waves and variants: India has faced waves of Covid-19 cases caused by variants, and the B. 1. 617 variant, known as the “double mutant,” is thought to be more transmissible than previous strains.
• Regional variation: While northern states are experiencing a strong increase, regions are showing mixed trends. For example:
– Karnataka, which faced a surge, is now seeing a decrease in cases.
– Maharashtra has remained solid for the past three weeks.
• Climate: Adverse weather conditions, coupled with diversified temperature and humidity, play a role in the recent outbreak by creating an environment conducive to viral transmission.
Covid-19 can cause a variety of symptoms, from mild to severe. Common symptoms include:
•Fever
•Cough
•Weakness
•Pain
•Rhinorrhea
• Stuffy nose
• Headache
In severe cases, patients would possibly experience reduced blood oxygen saturation and severe respiratory distress, requiring mechanical ventilation.
For you and to prevent the spread of the virus, follow Dr. Prasad’s guidelines:
1. Wash your hands: Wash your hands with soap and water for at least 20 seconds.
2. Avoid touching your face: Avoid touching your face, eyes, nose, and mouth.
3. Physical Distancing: Maintain a distance of at least 6 feet from other people, in crowded areas.
4. Wear masks: Wear masks, especially during periods of peak transmission.
5. Good hygiene: Cover your mouth and when sneezing or coughing.
6. Stay hydrated: Drink plenty of fluids to stay well hydrated.
7. Avoid others who are sick: Minimize close contact with others with respiratory symptoms.
8. Good indoor air circulation: Ensure ventilation inside.
9. Vaccination: Vaccinate yourself and decrease the severity of symptoms.
