Hidden camera at women's toilet: M.Sc. student Santosh M arrested

The deadly coronavirus that entered India while there was still nip in the air has beaten rising mercury, humid conditions, unique Indian genome and has entered monsoon season with more potency as fresh cases are only breaking all records in the country.

India recorded a single-day spike of record 24,850 new coronavirus cases on Sunday, taking its total tally to 6.73 lakh corona-positive cases.

Top Indian microbiologists were hopeful in March that after the 21-day lockdown, as summer approaches, the rise in temperature would play an important role in preventing the drastic spread of COVID-19 virus in India.

Several virologists hinted that by June this year, the impact of COVID-19 would be less than what it appeared in March-April.

The claims have fallen flat as the virus is mutating fast, becoming more potent than ever.

According to experts, the novel coronavirus is a new virus whose seasonality and response to hot humid weather was never fully understood.

"The theory was based on the fact that high temperatures can kill the virus as in sterilisation techniques used in healthcare. But these are controlled environment conditions. There are many other factors besides temperature, humidity which influence the transmission rate among humans," Dr Anu Gupta, Head, Microbiologist and Infection Control, Fortis Escorts Heart Institute, told IANS.

There is no built-up immunity to COVID-19 in humans.

"Also, asymptomatic people might be passing it to many others unknowingly. New viruses tend not to follow the seasonal trend in their first year," Gupta emphasized.

Globally, as several countries are now experiencing hot weather, the World Health Organization (WHO) reported a record hike in the number of coronavirus cases, with the total rising by 2,12,326 in 24 hours in the highest single-day increase since COVID-19 broke out.

So far over 11 million people worldwide have tested positive for the disease which has led to over 5,25,000 deaths, according to data from Johns Hopkins University. The US remained the worst-hit country with over 28 lakh cases, followed by Brazil with 15.8 lakh.

According to Sandeep Nayar, Senior Consultant and HOD, Respiratory Medicine, Allergy & Sleep Disorders, BLK Super Speciality Hospital in New Delhi, whether temperature plays a role in COVID-19 infection is highly debated.

One school of thought said in the tropical regions of South Asia, the virus might not thrive longer.

"On the other hand, another school of thought has found that novel Coronavirus can survive in a hot and humid environment and tropical climate does not make a difference to the virus. According to them, this is what distinguishes the novel coronavirus from other common viruses, which usually wane in hot weather," stressed Nayar.

Not much has been studied in the past and no definite treatment or vaccine is available to date.

"Every day, new properties and manifestation of the disease come up. As of now, the only way to prevent this monster is by taking appropriate precautions. Hand hygiene, social distancing, cough etiquette and face masks definitely reduce spread of COVID-19 infection," Nayar told IANS.

Not just top Indian health experts, even Indian-American scientists had this theory in mind that sunshine and summer may ebb the spread of the coronavirus.

Ravi Godse, Director of Discharge Planning, UPMC Shadyside Pennsylvania in the US told IANS in April: "In the summer, the humidity can go up as well, meaning more water drops in the air. If the air is saturated with water and somebody sneezes virus droplets into such air, it is likely that the droplets will fall to the ground quicker, making them less infectious. So the short answer is yes, summer/sunshine could be bettera.

According to Dr Puneet Khanna, Head of Respiratory Medicine and Pulmonology, Manipal Hospital, Delhi, COVID-19 death rates are not too different in tropical countries but since the disease affected them late it was yet to show its peak in these areas.

"The virus can survive well in hot and humid countries and this is proven now," he stressed.

Karwar, June 29: The additional sessions court, Sirsi town police station and office of the deputy superintendent of police in Uttara Kannada district were sealed on Sunday after an undertrial was found positive for Covid-19.

The undertrial, accused of stealing a bike, from Hubballi was arrested by Sirsi police and had initially tested negative. He was confirmed infected when his samples were tested the second time.

Dubai, Jul 5: Three Indians, who were repatriated on a chartered flight from the UAE on Friday, have been held in the state of Rajasthan after officials seized gold worth Dh2.2million from them, the government announced on Saturday.

They are likely to be placed under arrest along with 11 others, who were repatriated from Saudi Arabia, from whom gold worth Dh5.5million was seized, a statement from the government tweeted by Press Information Bureau in Rajasthan said.

The gold bars were hidden in emergency lamps, photos attached to the tweets showed.

The 14 passengers had arrived at the Jaipur International Airport by two chartered flights.

They were intercepted by the Customs team at the airport and 31.9kg of gold valued at Rs156,759,820 (Dh7.7million) concealed in the baggage was recovered from these passengers.

Three passengers arrived from Ras Al Khaimah by Spice Jet Flight SG9055 and 12 gold bars/bricks weighing 9.3kg valued at Rs.45,761,100 (Dh2.2million) were recovered from them, the statement said.

The Indian Consulate in Dubai confirmed to Gulf News that the flight was chartered by a private company for repatriating its employees.

It is suspected that the passengers were used as carriers to smuggle gold.

The other 11 accused had arrived from Riyadh and 22.65kg of gold bars, predominantly with Suisse markings, valued at Rs110,998,720 (Dh5.5million) were recovered from them.

“The said recovered gold bars have been seized under Section 110 of the Customs Act, 1962. The said passengers are being interrogated and are likely to be placed under arrest in terms of section 104 of the Customs Act, 1962,” the statement added.

Indian media had earlier reported similar cases in which stranded Indians were apparently lured to be carriers for smuggling gold on repatriation flights from various countries.

A spike in gold smuggling attempts using Indians getting repatriated after losing jobs was also reported from the Indian state of Kerala.
