Indian women should cover themselves fully like Arab women: Mate Mahadevi

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.

Apr 9: A panel of experts in the Karnataka state has suggested that the ongoing lockdown should be continued in districts identified as Covid-19 hotspots, including Bengaluru, to limit the spread of the pandemic.

IT companies and government offices providing essential services should be allowed to function with 50% staff, according to the committee headed by Narayana Health chairman Dr Devi Shetty, which submitted its report to chief minister BS Yediyurappa on Wednesday.

It has also asked the government to ease restrictions gradually and take adequate care over the next six months to contain the outbreak. The committee urged the government not to permit AC buses and metro services till April 30 and allow private vehicles only on alternate days (even-odd number-wise) for two weeks after April 15.

The government must close schools and colleges till May 31 and allow only inter-state movement of goods transport. The government could allow non-AC shops to open. It has suggested that the ban on inter-state train and flight services should continue.

Education minister S Suresh Kumar, who is the state Covid-19 spokesperson, said the Cabinet, which is meeting on Thursday, may discuss the recommendations and take a view on de-escalation of the lockdown.

Prime Minister Narendra Modi will interact with chief ministers through videoconference on April 11, after which the government will get an idea about the Centre’s thinking, he said.

While some states including Kerala, Maharashtra and Telangana have favoured continuation of the lockdown, Yediyurappa has not taken any stand publicly and has instead been implementing the Centre’s decision.

Six new cases

Karnataka on Wednesday reported six new Covid-19 positive cases, including that of a 65-year-old person in Kalaburagi, who died due to severe acute respiratory infection.

The health authorities have issued a notice to the private hospital -- where the deceased was initially admitted before being taken to a government hospital -- for not reporting the case to the government. The government has locked down the hospital, kept its entire medical team under quarantine, and police have registered a case of criminal negligence against the hospital authorities.

Of the other five positive cases, two had a travel history to Delhi, one had contact with a Dubai returnee and two others had close contacts with infected people.

This takes the total number of positive cases in the state to 181. Five people have died, while 28 have been discharged so far.

Bengaluru, Ju 2 As many as 19 deaths and 1,502 new COVID-19 cases were reported in Karnataka till 5 pm on Thursday, as per information provided by the State Health Department.
