Ahmedabad / Vadodara: What is common about cases recorded in Vadodara on Monday and in Ahmedabad on Sundays? The patients had been tested negatively with a RT-PCR test twice – but the third test detected the existence of Covid-19 and then the genomical sequence found the omicron variant.
In the case of a 27-year-old woman in Vadodara, he developed symptoms such as low-level fever after returning from England last week.
“He underwent a RT-PCR test before riding a flight according to the requirements.
Upon arrival in Mumbai, he returned to the test and the results were negative,” said a senior health department official.
“He then returned to Vadodara.
When he developed symptoms, he suggested another test and the presence of the virus was detected.” In the case of a pair of Tanzania, the invention of the opportunity was caused by a pre-procedure RT-PCR test that gave positive results.
They have been tested negatively in Mumbai and Ahmedabad and even when they boarded.
Experts show that symptoms of lighter or lack of symptoms make detection increasingly difficult.
Officials of the Senior Ministry of Health is not available to comment on whether some tests can become norms for passengers from ‘At Risk’ countries.
Dr.
Mukesh Maheshwari, a pathologist based in Ahmedabad, said that the way the sample was collected important as much as the kit.
“Nose and throat swabs can provide results, but if the viral load is low, the virus may not be detected immediately,” he said.
“Maybe the first two tests are done at short intervals, and with the third test, the viral load needed for detection is achieved.” Dr.
Maheshwari added: “The kit must include the s-genes also for better results.
In Delta, we have no method to see if some tests are needed for detection.” He proceeded by saying: “In the case of omicron, the requirements for the RT- PCR before traveling and on arrival gave us reference points.
” Analysis of 14 cases has so far indicated that only four symptoms, 12 under 50 years, are all fully vaccinated or partially vaccinated, and 12 have been under medical observations when the omicron status they are known.
In two cases, some close relatives have also been positively tested.
