A man tested positive for COVID in the first case of the infection in Uttar Pradesh’s Gautam Buddh Nagar after several months, officials said on Thursday.

For travel: Amid a rise in cases travellers are worried that COVID restrictions will be back. There is no plan so far to make RT-PCR testing for Covid-19 mandatory at airports for travellers, sources told News18.

According to Dr Rajeev Jayadevan, co-chair of the IMA Covid Task Force, the new strain can be problematic for people of old age and those with multiple comorbidities.

Former World Health Organisation (WHO) chief scientist Dr Soumya Swaminathan said that there was no need to panic. She urged people to wear masks and avoid going to closed crowded spaces with poor ventilation.
“If you have symptoms, stay at home. Wash your hands regularly. If you have prolonged symptoms then do visit the hospital… Masking is not mandatory but it should be voluntary,” she added.

The number of fresh COVID-19 cases in Singapore jumped to 965 in the past week, up from 763 the previous week. Patients admitted to intensive care units (ICU) went up from 23 to 32 in the same period.
These are the highest numbers of new weekly hospitalisation and ICU admissions for COVID-19 patients in 2023, according to a report in TODAY newspaper. Most COVID-19 patients are infected by JN.1.

For travel: Singapore on Monday reintroduced the use of masks in crowded places, particularly indoors.

The government has issued guidelines for travellers and citizens. The health ministry has strongly encouraged the public to wear a mask in crowded places even if they are not sick, especially in indoor settings, or when visiting or interacting with vulnerable persons, the ministry said. “Travellers should adopt the relevant travel precautions, such as wearing a mask at the airport, purchasing travel insurance, and avoiding crowded areas with poor ventilation,” it said.

“Do not be alarmed but at the same time take precautionary measures. Maintain your distance from one another, practice good hygiene, wear masks indoors or in crowded spaces and get booster shots, especially those in the high-risk categories.”


The country’s health ministry has confirmed the detection of JN.1. At least 41 cases were confirmed on Wednesday.

“Like other Omicron subvariants, most patients who had contracted JN.1 experienced mild symptoms,” the country’s disease control and prevention director general Maxi Rein Rondonuwu said.

The United Kingdom

Cases of COVID-19 are rising in the UK, especially in England and Scotland. One in 24 people in the two places had the infection on 13 December compared to one in 55 on 29 December, according to data from the Office of National Statistics (ONS) and the UK Health Security Agency (UKHSA).

London is the worst-affected area as the infectious JN.1 variant spreads rapidly.

For travel: There are no mask mandates at airports or airlines if you are travelling to the UK.

“At this time of year, the cold weather, shorter days and increased socialising mean that the potential for transmission of respiratory viruses like Covid-19 is particularly high,” Steven Riley, director general for data and surveillance at the UKHSA was quoted as saying by Bloomberg. “This, as well as the possible impact of new variants, means it’s not unexpected to see cases rising.”

The United States

In the US, COVID levels have reached the highest since last December in parts of the country, according to wastewater data analysis from the Centres for Disease Control and Prevention.

Some states with “very high” levels of Covid include New Jersey, North Carolina, Maryland, Indiana, Delaware, and Michigan, among others. New York, Virginia, Texas, California, and Virginia are states with “high levels” of infections.

JN.1 is causing approximately 20 per cent of new infections in the country, making it the fastest-growing strain.

For travel: There have been no restrictions imposed so far.

But Dr Peter Chin-Hong, a University of California San Francisco infectious disease expert, told the Los Angeles Times that with the rising viral levels, he is worried are “going to translate into hospitalisations around Christmastime.”

The CDC has said that there is no evidence that JN.1 presents an increased risk to public health relative to other currently circulating variants. It added that an updated shot could keep Americans protected against the variant.
