Covid-19 surge across Asia: What’s causing the spike in Singapore, Hong Kong?

Singapore has been witnessing a significant surge in Covid-19 cases. The number of Covid cases rose to 14,200 in May compared to the 11,100 cases last month. The sudden surge in cases has raised concerns about the spread of a new variant. 

 

Not just in Singapore, several parts of Asia are reporting a spike in Covid-19 cases. Hong Kong, China and Thailand have reported a fresh surge. 

 

The Ministry of Health informed that, "LF.7 and NB.1.8 are the main Covid-19 variants circulating in Signapore."  LF.7 and NB.1.8 are descendants of JN.1 variant that is used in Covid-19 vaccines. 

 

The health ministry has advised the public to be vigilant in the wake of the rising hospitalisations. 

 

What are the current Covid wave symptoms? 

 

The symptoms associated with the current Covid wave include sore throat, nausea, vomiting, cough, brain fog and conjunctivitis. Though the symptoms are mild, the experts have asked to monitor their health and seek medical attention in case required. 

 

In Hong Kong, experts warned that "the virus activity is quite high". Reportedly, as of May 3, 31 deaths were reported among 81 severe Covid cases. Also, 83 per cent of the people infected are those above the age of 65 years. The increase in the viral load was seen in sewage samples. An increase in respiratory samples testing positive for Covid-19 was also noted. 

 

Meanwhile, Thailand's Department of Disease Control also reported two cluster outbreaks in 2025. 

 

In India, though many are not undergoing the Covid-19 tests, data from the ICMR labs reveal that there are cases. However, health officials have advised people not to panic and adopt the basic steps of hygiene and avoid crowded places without a mask.
