Heavy rains lash coastal Karnataka, lightning strike kills student in Kasargod

Bengaluru, Mar 10: With concerns growing by the day, the Karnataka government is readying three more labs to test throat swab samples.

Currently, only two labs in Bengaluru — National Institute of Virology and Virus Research and Diagnostics Laboratory (VRDL) lab attached to Bangalore Medical College and Research Institute — are categorised biosafety level 2+, a requirement for coronavirus tests.

Now, the government is working on upgrading three more labs, one each in the government medical colleges at Hassan, Mysuru and Shivamogga. “The labs will be ready within one week,” the authorities said.

Currently, the labs are testing only throat swab samples of suspected patients and taking 24 hours to give the results. “A patient’s blood sample will be collected only if he or she tests positive for covid-19 infection in the first throat swab sample.

While earlier the state would send all samples of suspected coronavirus cases to NIV, Pune, the two labs were upgraded to biosafety level 2+ in mid-February.

Mangaluru, Jul 2: A frontline covid-19 warrior who was working in the Wenlock Covid hospital in the city has been tested positive for the coronavirus. 

Sources said that he was a pathologist working in covid testing laboratory of the Wenlock Covid hospital.

A few days ago, a senior health official had tested positive for the covid-19.

Dakshina Kannada has so far recorded deaths of 18 covid-19 patients. A total of 14,137 samples have been tested, out of which 13,040 have turned out negative, and 833 positive, including 10 persons from other districts. 372 cases are currently active.

San Diego, Apr 15: Several people lost their sense of smell or taste weeks ago globally and are still waiting for it to come back and now, researchers have identified an association between sensory loss and novel coronavirus 2019 (COVID-19) infection, indicating that loss of smell and taste may be considered as early symptoms of the deadly disease.

Interestingly, the study also found that persons who reported experiencing a sore throat more often tested negative for COVID-19.

The team from University of California-San Diego found high prevalence and unique presentation of certain sensory impairments in patients positive with COVID-19.

Of those who reported a loss of smell and taste, the loss was typically profound, not mild.

"Based on our study, if you have smell and taste loss, you are more than 10 times more likely to have COVID-19 infection than other causes of infection. The most common first sign of a COVID-19 infection remains fever, but fatigue and loss of smell and taste follow as other very common initial symptoms," explained study researcher Carol Yan from UC San Diego.

"We know COVID-19 is an extremely contagious virus. This study supports the need to be aware of smell and taste loss as early signs of COVID-19," Yan added.

For the findings, published in the journal International Forum of Allergy and Rhinology, the research team surveyed 1,480 patients with flu-like symptoms and concerns regarding potential COVID-19 infection who underwent testing at UC San Diego Health from March 3 through March 29, 2020.

Within that total, 102 patients tested positive for the virus and 1,378 tested negatives. The study included responses from 59 COVID-19-positive patients and 203 COVID-19-negative patients.

Encouragingly, the rate of recovery of smell and taste was high and occurred usually within two to four weeks of infection.

"Our study not only showed that the high incidence of smell and taste is specific to COVID-19 infection but we fortunately also found that for the majority of people sensory recovery was generally rapid," said Yan.

"Among the COVID-19 patients with smell loss, more than 70 per cent had reported improvement of smell at the time of the survey and of those who hadn't reported improvement, many had only been diagnosed recently," she added.

Sensory return typically matched the timing of disease recovery.

In an effort to decrease the risk of virus transmission, UC San Diego Health now includes loss of smell and taste as a screening requirement for visitors and staff, as well as a marker for testing patients who may be positive for the virus.

"It is our hope that with these findings other institutions will follow suit and not only list smell and taste loss as a symptom of COVID-19, but use it as a screening measure for the virus across the world," Yan said.
