What international travellers should know amidst rising Covid-19 cases
Travellers heading abroad this summer are being urged to exercise caution as COVID-19 cases are rising again in parts of Asia. Countries such as Singapore, Thailand, Hong Kong, and India have reported a fresh uptick in infections, driven largely by new Omicron sub-variants.According to a report by Conde Nast Traveller, despite the rise in numbers, travel remains unaffected. Flights are operating on schedule and there are no quarantine or testing requirements for domestic or international travellers. However, health authorities continue to monitor the situation.For travellers, the advice is to stay cautious, especially if elderly, immunocompromised, or dealing with chronic conditions. Doctors recommend that these groups assess the need for travel and consider postponing non-essential trips.All travellers are advised to wear masks in crowded places, carry hand sanitiser, and avoid contact with individuals showing symptoms. Vaccination remains the best defence. While India has not recommended a fresh booster, Singapore and Hong Kong are advising additional doses for high-risk groups.

As per the CN Traveller report, Singapore's Ministry of Health reported over 14,000 cases in the second week of May. In Hong Kong, respiratory sample positivity rates jumped from 1.7% in March to over 11% this month. Thailand has reported localised clusters in Bangkok, Chon Buri, and Samut Prakan, especially following April's Songkran festivities.
India has also seen a modest increase, crossing the 1,000-case mark earlier this week. According to the Indian Council of Medical Research, the surge is linked to four fast-spreading sub-variants—JN.1, NB.1.8.1, LF.7, and XFG. The first three are currently the most common.While the World Health Organization has not issued any travel warnings, it has classified NB.1.8 and LF.7 as "Variants Under Monitoring." No country in the region has reinstated border restrictions or lockdowns.India's Health Ministry confirmed 753 active cases nationwide as of May 26, 2025, with Kerala reporting the highest number at 430 cases. Maharashtra and Delhi follow with 210 and 104 cases, respectively. Officials maintain that most cases remain mild and manageable.

NB.1.8.1 Covid-19 variant makes up 10% cases globally: Should you worry?
Just when many believed Covid-19 was in the rear-view mirror, a new variant has quietly gained ground. NB.1.8.1, first detected in China in January 2025, now accounts for one in ten Covid-19 cases globally—up from just one in forty a month ago. It has spread across twenty-two countries so far. What is NB.1.8.1 variant? According to the World Health Organization, NB.1.8.1 is among several fast-evolving Omicron-lineage variants. From January to May 2025, global dominance shifted from XEC to LP.8.1, with NB.1.8.1 now surging rapidly. The WHO has classified NB.1.8.1 as a Variant Under Monitoring due to its rise in prevalence and potential public health implications. Officials stress that while vigilance is crucial, there is no cause for alarm. Vaccination remains the best protection against severe illness and death. How NB.1.8.1 behaves and how severe it really is NB.1.8.1 is a sublineage of the Omicron JN.1 family. It carries similar characteristics—high transmissibility, but mostly mild to moderate illness. It also includes new mutations on the spike protein, which may enhance its ability to spread and evade immunity. So far, there is no evidence to suggest NB.1.8.1 causes more severe disease, hospitalisations or death compared to previous variants. NB.1.8.1 symptoms: What to watch for Common symptoms include: Dry, persistent cough Runny or blocked nose Fatigue and general body aches Sore throat Fever or chills Headache or hoarseness in some cases Many report being able to go about daily activities but feel unusually tired and sluggish. Are vaccines still effective against NB.1.8.1? Updated vaccines, including the latest Omicron-targeted boosters, are designed to protect against the JN.1 family. While they may not prevent all infections, they continue to reduce the risk of hospitalisation and severe outcomes. Expert guidance includes: If you are over sixty, have chronic health conditions or are immunocompromised, get a booster if it has been more than six months since your last dose If you are healthy and under sixty, no new dose is required at present Use masks in public transport and crowded indoor spaces How to manage NB.1.8.1 symptoms at home In most cases, NB.1.8.1 does not require hospitalisation. Here is what helps: Rest and stay well hydrated Use paracetamol or other over-the-counter medications for fever or aches Recovery generally takes five to seven days If you are elderly or immunocompromised, speak to your doctor early. Antiviral medication is most effective within five days of the onset of symptoms. Warning signs: When to seek emergency help Seek urgent medical care if you experience any of the following: Difficulty breathing Chest pain or tightness Confusion or trouble staying awake Severe dizziness or fainting Do not panic, but stay informed Experts believe NB.1.8.1 will follow a familiar seasonal pattern seen with earlier variants—periodic surges during winter and summer months. Most infections remain mild. Vaccines continue to work. Keep an eye on symptoms, isolate if unwell, and consult your doctor when in doubt.

Over 5,000 active Covid cases in India; four deaths reported in 24 hours
India's active Covid case count crossed the 5,000 mark with Kerala being the most affected state followed by Gujarat, West Bengal and Delhi, according to the data released by the Union Health Ministry on Friday. As per the health ministry data on Friday, Kerala saw 192 new Covid-19 cases, Gujarat 107, West Bengal 58, and Delhi 30 that significantly contributed to a spike of 498 new cases of the infection in the country in the last 24 hours. There are currently 5,364 active reported Covid cases in India with four fresh deaths that have been reported in the last 24 hours. Although official sources have affirmed that most cases are mild and managed under home care, the government is taking steps to ensure preparedness against the disease by conducting mock drills after the information was provided by the ministry. All states have been instructed to ensure availability of oxygen, isolation beds, ventilators, and essential medicines after the rise in Covid cases. Since January this year, 55 covid related deaths have been reported in the country. There were a total of 257 active patients in the country on May 22, 2025. A series of technical review meetings were held on June 2 and 3 under chairpersonship of Dr Sunita Sharma, Director General of Health Services (DGHS). She was accompanied by representatives of Disaster Management Cell, Emergency Management Response (EMR) Cell, National Centre for Disease Control (NCDC), Indian Council of Medical Research (ICMR), Integrated Disease Surveillance Programme (IDSP) and Central Government Hospitals in Delhi. Representatives from all states and union territories also presided over the meetings to keep a check on the current COVID-19 situation and relief measures, and ensure that there are no lapses in dealing with the rising cases. The state and district surveillance units under IDSP are also closely monitoring cases under Influenza Like Illness (ILI) and Severe Acute Respiratory Illness (SARI), official sources said on June 4. "Testing is recommended for all admitted SARI cases and 5 per cent of ILI cases as per guidelines. Positive SARI samples are sent for Whole Genome Sequencing through the ICMR VRDL network," an official source affirmed.
