Scientists confirm smell and taste loss as early signs of COVID-19

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.

French Nobel prize winning scientist Luc Montagnier has sparked a fresh controversy by claiming that the SARS-CoV-2 virus came from a lab, and is the result of an attempt to manufacture a vaccine against the AIDS virus.

In an interview given to French CNews channel and during a podcast by Pourquoi Docteur, professor Montagnier who co-discovered HIV (Human Immunodeficiency Virus) claimed the presence of elements of HIV in the genome of the coronavirus and even elements of the "germ of malaria" are highly suspect, according to a report in Asia Times.

"The Wuhan city laboratory has specialized in these coronaviruses since the early 2000s. They have expertise in this area," he was quoted as saying.

The theory that Covid-19 virus originated in the lab is making rounds for quite some time.

US President Donald Trump last week acknowledged Fox News report that the novel coronavirus may have been accidentally leaked by an intern working at the Wuhan Institute of Virology in China.

The Fox News, in an exclusive report, based on unnamed sources has claimed that though the virus is a naturally occurring strain among bats and not a bioweapon, but it was being studied in Wuhan laboratory.

The initial transmission of the virus was bat-to-human, the news channel said, adding that the "patient zero" worked at the laboratory. The lab employee was accidentally infected before spreading the disease among the common people outside the lab in Wuhan city.

Professor Montagnier was awarded the 2008 Nobel Prize in Medicine for the identification of AIDS virus, with his colleague professor Franeoise Barre-Sinoussi.

His fresh claim on coronavirus, however, received criticism from scientists, including his colleagues.

"Just in case you don't know. Dr Montagnier has been rolling downhill incredibly fast in the last few years. From baselessly defending homeopathy to becoming an antivaxxer. Whatever he says, just don't believe him," tweeted Juan Carlos Gabaldon.

As per a recent Washington Post, two years ago, the US embassy officials in China raised concerns about the insufficient biosafety at the Chinese government's Wuhan Institute of Virology where deadly viruses and infectious diseases are studied.

Though the institute, located quite close to the Wuhan wet market, is China's first biosafety level IV lab, the US state department had warned in 2018 about "serious shortage of appropriately trained technicians and investigators needed to safely operate this high-containment laboratory".

Bengaluru, Feb 28: The Liquefied Petroleum Gas penetration in Karnataka is 'absolutely 100 per cent' due to the Prime Minister Ujjwala Yojana, Indian Oil Corporation Karnataka Executive Director D L Pramodh said here on Friday.

In 2014, LPG penetration in the State was only 68 per cent, but after the PMUY, massive number of gas connections were given in the last five years, he said, adding, "It is absolutely 100 per cent today."

"There are 1.6 crore LPG connections out of which around 31.5 lakh -- or around 20 per cent -- come under the PMUY. The 100 per cent LPG penetration in the state will help women in rural areas to make their kitchens smokeless. Against the national average of 2.88 cylinders per family per PMUY annually, the figure is Karnataka 3.4 cylinders in Karnataka," Pramodh told reporters.

On the initiative of blending ethanol with petrol, he said it's 8.6 per cent in Karnataka, the highest comparedto other states, where it's five per cent to 5.5 per cent. The state aims to increase it to 10 per cent. By March 31, the IOC would commission the Rs 10 crore Vapour Recovery System at the Devanagonthi terminal on the city outskirts which would ensure that vapour does not go out in the air when tankers are being filled with fuel. "This is an important measure taken tominimise pollution", he said.

Pramodh also said the IOC has started mobile fuel dispensers, delivering fuels at the doorsteps.

Regarding the IOC's preparedness for Electric Vehicle charging stations, Pramodh said the Ministry of Power has given the company a target to set up 500 charging stations across India in the first phase. The IOC has already signed MoUs with NTPC, Power Grid Corporation Limited, Hyundai Motors, Tech Mahindra and Tata Power in this regard.

In Karnataka, 58 sites have been identified for setting up charging and battery swapping stations.

"Total electric vehicle charging facilities planned by IOC in Karnataka by March 31 is 34, out of which 26 will be EVcharging sites and eight battery swapping stations," Pramodh said.

Bengaluru, July 28: Former prime minister and JD(S) chief H D Deve Gowda today threatened to launch a state-wide agitation in against the amendments made to the Karnataka Land Reforms Act.

Gowda’s opposition to the new law comes even as Congress leader Siddaramaiah is also doggedly pursuing it.

Demanding that the state government immediately rollback the ordinance empowering these amendments, the octogenarian leader said he personally would take to streets if the government failed to budge.

The B S Yediyurappa government has liberalised the land reforms law by removing restrictions on non-agriculturists from purchasing and owning farm lands.

The government has also amended the APMC Act and has tweaked labour laws, which are all “against the interest of the state and must be rolled back,” Gowda said.

Speaking to reporters here, Gowda stated that he had already written thrice to Chief Minister B S Yediyurappa in this regard. "The ordinances have to be taken back. The amendments to Karnataka Land Reforms Act, by repealing sections 79-A, B and C, is an anti-farmer move. The APMC Act amendment, too, is against the interest of the state. The government has failed to speak about the impact of these amendments," said Gowda, who is now a Rajya Sabha member.

Elaborating on the amendment to the Land Reform Act, the JD(S) patriarch opined that by throwing open agricultural land ownership to anybody at all, the government was only helping real estate developers while pushing farmers into a “vulnerable” situation.

Amidst all this, there are now reports of funds misappropriation in Covid-19 relief measures and in procurement of medical equipment, he said, adding that it seemed like only the corrupt became stronger over time.

Further, Gowda lambasted both national parties for creating political unrest, referring to the ongoing political crisis in Rajasthan and the recent developments in Madhya Pradesh. However, he added that he would not wish to dwell on it much, while emphasising that his focus was primarily on strengthening his own party at this point in time.
