In mid-October 2022, as the lamps of Diwali and the long run of autumn festivals drew near, the civic body that governs Mumbai and the health department of Maharashtra turned their attention back to a virus that many had hoped to leave behind. Daily COVID-19 counts in the city had begun to climb in the second week of the month, and officials pointed to newer Omicron descendants, BQ.1, BA.2.3.20 and the recombinant XBB, as reasons for caution.

Mumbai civic body urges COVID precautions ahead of festive season as new Omicron sub-variants emerge
The sooner you know you are sick, the easier it is to judge treatment
Mark
Why issue this advisory now, if there's no surge yet?
Mimi
Because of timing. Diwali and other festivals fall in the next fortnight, and the BMC says daily cases already ticked up in the second week of October.
Mark
What's the specific worry about the festivals?
Mimi
Crowds, fairs, and enclosed spaces with poor ventilation, plus a tendency to relax safe behaviour during celebrations.
Luke
Let me slow down on the variants. What's actually established?
Mimi
The BMC says BQ.1, BA.2.3.20 and XBB have been detected in Maharashtra, and that they grow faster than variants like BA.2.75 and evade immunity to some degree.
Luke
That's the civic body's characterisation. The advisory gives no case counts, no share of infections from these variants, and no data on severity.
Mark
So the upward trend is real but unquantified?
Luke
In this report, yes. We're told cases rose, not by how much.
Mimi
Which is why the advice is cautious rather than alarmed: vaccinate, boost, mask in crowds, test early.
Mark
And who should act fastest?
Mimi
People with breathing difficulty, the immunocompromised, and recent travellers from countries where the virus is prevalent should seek medical advice immediately.
Luke
Whether this becomes a real wave will only show in post-Diwali numbers. Right now it's a forecast.
Le Pouls
- Daily COVID-19 cases in Mumbai have turned upward, and the city's civic body is no longer treating the trend as background noise.
- Diwali and a string of festivals are bringing crowds into enclosed, poorly ventilated spaces, exactly the conditions officials fear most.
- Three Omicron sub-variants, BQ.1, BA.2.3.20 and XBB, are being cited for growth advantages and some ability to evade immunity.
- The BMC and Maharashtra health officials are pushing vaccination, boosters, masks, ventilation and rapid testing as the first line of defence.
- The outcome now hinges on whether case numbers keep climbing after the festival gatherings end.
In mid-October 2022, as the lamps of Diwali and the long run of autumn festivals drew near, the civic body that governs Mumbai and the health department of Maharashtra turned their attention back to a virus that many had hoped to leave behind. Daily COVID-19 counts in the city had begun to climb in the second week of the month, and officials pointed to newer Omicron descendants, BQ.1, BA.2.3.20 and the recombinant XBB, as reasons for caution. It is a familiar human pattern: a season of togetherness arrives, and the same crowds that make celebration meaningful also give a patient virus its opportunity. The authorities were not sounding an alarm about a surge already underway, but asking the city to remember habits it had once known well before the coming weeks tested them.
On Tuesday, the Brihanmumbai Municipal Corporation, the civic body that runs Mumbai, issued an advisory asking residents to keep up COVID-appropriate behaviour through the coming festive season. Its goal was simple: to get ahead of a rise in cases before it gathered force.
The warning carried weight because the city's own figures were moving in the wrong direction. Daily cases in Mumbai had trended upward during the second week of October, and the Maharashtra health department had cautioned that infections could climb further through the winter and the festivals. State officials pointed to new variants detected within the state, BA.2.3.20 and BQ.1, and the BMC added XBB, a recombinant of BA.2.75 and BJ.1. According to the civic body, these strains show a growth advantage over earlier Omicron variants and some capacity to evade immunity, which is why it wanted precautions in place now.
The festive calendar is what concerned the authorities most. Diwali and several other celebrations were due over the next fortnight, and the BMC described this as a critical period, since people tend to let safe habits slip when they are gathering. Crowds, events and fairs in enclosed, poorly ventilated spaces were the situations it singled out.
The guidance was practical. Unvaccinated residents were urged to get their shots, and those eligible were asked to take a booster. People were told to wear masks in crowded places, wash hands often, keep indoor air moving, cover coughs and sneezes, and steer clear of close contact with anyone showing symptoms. Anyone with respiratory symptoms was asked to get tested promptly, since early knowledge of an infection makes it easier to decide when treatment or hospital care is needed. People having trouble breathing, immunocompromised patients and recent travellers from countries where the virus is widespread were told to seek medical advice without delay.
This was a warning rather than a report of a surge. What will matter is whether case numbers keep rising once the festival gatherings are over.
On Tuesday, the Brihanmumbai Municipal Corporation, the civic body that runs Mumbai, put out an advisory asking residents to keep following COVID-19-appropriate behaviour through the coming festive season. The aim, it said, was to head off a rise in cases.
The advisory arrived with a warning from the Maharashtra health department. State health officials have cautioned that infections could climb, particularly through winter and the festivals, and they pointed to new variants reported from within Maharashtra: BA.2.3.20 and BQ.1.
The city's own numbers gave the warning some weight. According to the BMC, daily COVID-19 cases in Mumbai trended upward in the second week of October.
The civic body named three new Omicron sub-variants detected in the state. BQ.1, which it described as the US variant, and BA.2.3.20 are two. The third is XBB, a recombinant of BA.2.75 and BJ.1. The BMC said these have a growth advantage over other Omicron variants such as BA.2.75, along with immune-evasive properties. That is the reason it gave for urging precautions now.
The festive calendar is what worries the authorities most. Diwali and several other festivals will be celebrated over the next fortnight. The BMC called the season a critical period, since people tend to let COVID-safe habits slip during festivals. Large gatherings, events, fairs and crowds in enclosed, poorly ventilated spaces are the situations it flagged.
The advice itself was practical. Residents who have not yet been vaccinated should get the shots, and those eligible should take a booster dose. Masks should be worn in crowded places. People should wash their hands often, keep indoor spaces well ventilated, and cover the nose and mouth with a handkerchief or tissue when sneezing or coughing. They should also avoid close contact with anyone who has symptomatic COVID-19.
The BMC also asked anyone who develops symptoms of a respiratory infection to get tested immediately. Its statement tied early detection to how well treatment works: the sooner you know you are sick, it said, the easier it is to judge when you need treatment or hospitalization.
Certain groups were told to seek medical advice without delay. They are people having difficulty breathing, immunocompromised patients, and those who have recently visited countries where the coronavirus is prevalent.
The advisory is a warning, not a report of a surge. The thing to watch is whether case numbers keep rising once the Diwali gatherings are over.
