Doctors say infections remain mild, resembling seasonal viral illness, with most detected during routine checks and few requiring hospitalisation, suggesting influenza‑like pattern.
Bengaluru has reported 121 Covid-19 cases between January 1 and July 17 this year, with doctors stressing that the infections recorded so far have largely been mild and there is no evidence of a fresh wave. Health experts say the virus is now behaving like other seasonal respiratory infections, with occasional changes in case numbers expected over time.
According to official data from the Health and Family Welfare, “Bengaluru recorded 121 positive cases from 3,820 Covid tests conducted during the period, resulting in a test positivity rate of about 3.2 per cent. Across Karnataka, 166 cases have been detected from 4,550 samples tested, taking the state’s positivity rate to nearly 3.6 per cent. No Covid-related deaths have been reported in Karnataka this year.”
Although the Indian SARS-CoV-2 Genomics Consortium (INSACOG) is yet to update its genomic surveillance data for the current season, doctors say Omicron sub-lineages such as BA.3.2 (Cicada), XFG (Stratus) and NB.1.8.1 (Nimbus) are among the variants believed to be in circulation, along with JN.1, which was one of the dominant lineages during 2024 and 2025.
BA.3.2, informally referred to as Cicada, has been reported in several countries, including India. Researchers are studying its immune-evasion potential, but there is no evidence so far that it causes more severe illness than other currently circulating variants. The nickname “Cicada” draws a parallel with the insect’s long dormant period, reflecting the variant’s re-emergence after first being identified in 2022. Nimbus (NB.1.8.1) is also being monitored for mutations that may help it partially evade existing immunity, while reported Stratus (XFG) infections have largely remained mild. Experts say genomic surveillance is continuing to better understand the spread and behaviour of these sub-lineages.
Doctors say most patients are experiencing symptoms similar to those of a common viral infection, including fever, sore throat, cough and body ache, with very few requiring hospitalisation. Many of the positive cases are being identified during physician-advised investigations or routine preoperative fitness assessments rather than through dedicated Covid testing.
Medical experts believe the actual number of infections in the community could be higher, as many people with mild symptoms do not undergo testing. They point out that Covid-19 has now settled into a pattern similar to influenza, where periodic increases in infections are expected as immunity declines and newer variants emerge.
Hospitals are also reporting cases of influenza, dengue, chikungunya and typhoid, reflecting the circulation of several seasonal illnesses at the same time. Doctors advise people, especially senior citizens and those with underlying health conditions, to continue following basic precautions such as maintaining hand hygiene, covering the mouth and nose while coughing or sneezing and wearing a mask in crowded places or when experiencing respiratory symptoms. They stress that there is no reason for panic, but remaining cautious is the best way to prevent the spread of infection.
