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, Jul 3: Accredited Social Health Activists (ASHAs) in Karnataka have emerged as a "crucial pillar in the state's success" in combating Covid-19, the Union Health Ministry said on Friday.

Acknowledging and praising their work, the ministry said they have been actively participating in household surveys in the state, screening inter-state passengers, migrant workers and others in the community for symptoms of the infection,

“Around 42,000 ASHAs have emerged as a crucial pillar in the state's success” in combating Covid-19, the ministry said.

"Recognizing the increased vulnerability of certain population groups to Covid-19, in a one-time survey to identify households with the elderly, persons with co-morbidities, and immune-compromised individuals, about 1.59 crore households were covered," the ministry said in a statement.

ASHAs regularly monitor such high-risk groups in their area with a periodicity of follow-up visits varying from once a day in the containment zones to once every 15 days in other areas, it said.

They also visit the houses of persons complaining influenza-like-illness (ILI) symptoms and severe acute respiratory infections (SARI), besides high-risk individuals who have called the state health department helpline numbers, the ministry said.

ASHAs are a part of the Rural Task Force, headed by Panchayat Development Officer (PDO) at the Gram Panchayat level, for addressing public grievances on both Covid-19 and non-Covid-19 related services.

ASHAs are trained female community health activists selected from the village itself and accountable to it. They are trained to work as an interface between the community and the public health system.

In the urban areas too, they have been at the forefront of dissemination of various awareness activities in fever clinics and swab collection centres in urban areas.

They have also actively screened cases of ILI and SARI in urban areas. They are also part of the screening teams at international and interstate check-posts.

Karnataka has reported 272 Covid-19 deaths and 18,016 cases, according to the health ministry data updated at 8 AM.
