Transfer: Rohini challenges CAT order in HC

Mangaluru, May 5: The Dakshina Kannada district administration has denotified two containment zones, Sampya in Puttur and Thumbe in Bantwal. They were declared containment zones after one coronavirus positive case was reported from each area.

All the primary and secondary contacts of the patients have completed home quarantine period, said DC Sindhu B Rupesh.

The district administration hitherto had already denotified three other such containment zones based on a report of DHO,  after no new case was reported in the area in the last 28 days.

At present, the district has six containment zones-- Shakthinagara, Boloor, First Neuro Hospital in Mangaluru city, Uppinangady in Puttur, Kasaba and Narikombu in Bantwal taluk.

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.

New Delhi, Feb 20: Microsoft has begun testing its free open-source software called "ElectionGuard" in a small Wisconsin town in the US that aims to make voting more secure, verifiable and efficient.

"ElectionGuard" will enable end-to-end verification of elections, open results to third-party organisations for secure validation, and allow individual voters to confirm their votes were correctly counted.

It enables government entities, news outlets, human rights organisations or anyone else to build additional verifiers that independently can certify election results have been accurately counted and have not been altered, according to the company.

The software would create a paper trail and assure voters their votes were properly tallied.

"On Tuesday, Fulton residents are using the technology while choosing who will join the local school board and hold a seat on Wisconsin's state Supreme Court," reports CNBC.

With the test, the company aims to see if voters like the experience and make sure everything works fine.

In May last year, Microsoft CEO Satya Nadella announced "ElectionGuard".

According to Tom Burt, Corporate Vice President, Customer Security and Trust, voting system manufacturers will be free to build ElectionGuard into their systems in a variety of ways.

"These are exciting steps that enable individual voters to confirm their vote was properly counted, and assures those voters using an ElectionGuard system of the most secure and trustworthy vote in the history of the US," Burt said in a recent blog post.

"ElectionGuard" is not intended to replace paper ballots but rather to supplement and improve systems that rely on them, and it is not designed to support internet voting.

The software provides each voter a tracker with a unique code that can be used to follow an encrypted version of the vote through the entire election process via a web portal provided by election authorities.

During the process of vote-casting, voters have an optional step that allows them to confirm that their trackers and encrypted votes accurately reflect their selections.

But once a vote is cast, neither the tracker nor any data provided through the web portal can be used to reveal the contents of the vote.

After the election is complete, the tracker codes can be used by voters to confirm that their votes were not altered or tampered with and that they were properly counted, said Microsoft.

On the security front, "ElectionGuard" uses something called homomorphic encryption - which enables mathematical procedures "like counting - to be done with fully encrypted data".
