II PU chemistry re-exam on March 29

Bengaluru, May 10 The asymptomatic and healthy people among international passengers will now have to undergo institutional quarantine for 14 days, according to the new standard operating procedure (SoP) issued by the Karnataka government for a third time.

The SoP, which has been revised twice, was issued by the Health and Family Welfare Department on Saturday, May 9.

The international passengers will be divided into two categories upon their arrival at the airports. Symptomatic will be directly sent to the covid-19 hospitals. Asymptomatic will not be allowed to go home directly. They will be sent for mandatory quarantine for 14 days in hotels and guest houses. 

Earlier, international passengers had to undergo seven days of institutional and seven days of home quarantine.

Passengers will also be tested only twice — once on arrival and for the second time on the 14th day — instead of the earlier decision to test thrice. They will be discharged from the facility if they test negative.

The first group of 350 people are expected to arrive from London at 3 am on Monday at the Kempegowda International Airport, said Lakshman Reddy, Joint Director, Social Welfare Department. 

Flights are expected from Singapore on May 13, Jeddah on May 14 and San Francisco on May 15. 

Among the stranded include 4,408 tourists and visitors, 3,084 students, 2,784 migrants and 557 ship crew.

Udupi, June 19: The coronavirus has claimed second life in the coastal district of Udupi. The victim is a 54-year-old person who had returned from Mumbai.

A resident of Tekkatte in Kundapur taluk of Udupi district, the person was among four travellers that returned together from Maharashtra on June 18. 

Even though all four were asymptomatic they were home quarantined separately as per norms. According to sources, all of a sudden he collapsed at home and died. His throat swabs tested positive for the coronavirus, according to deputy commissioner G Jagadish.

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.
