NYCOVID-19 Detailed Mental Health Web Search Details During Lockdown

A JAMA Today’s study, which analyzes Internet search trends, found that anxiety, panic attacks, and insomnia queries increased during the March blockade across New York, and depression and suicide searches remained at expected levels. I found out.

Quarantine has shown adverse effects on mental health resulting from social isolation, restricted activity, financial loss due to workplace closures, and fear of illness.The· JAMA The study sought to assess mental health concerns in some of the New York blockades by analyzing Internet search trends for mental health issues from March 22nd to May 15th.

The authors of the study used anonymous, published Google Trends and user location data to compare the search volume for certain mental health terms to the expected volume based on historical search data. Relative search volume (RSV) (absolute search volume standardized between 0 and 100) was calculated for each week of lockdown.

Searches for anxiety increased significantly, with RSV remaining an average of 18% higher than expected for three consecutive weeks after the March 22 blockade order. [95% prediction interval (PI), 5% to 29%].. Panic attack RSV surged in the first week of blockade (56% increase, 95% PI, 37% to 97%) and remained at higher than expected levels for 5 consecutive weeks, but insomnia search Is expected during the study period, which was higher than 21% (95% PI, 1% to 55%).

Importantly, Internet searches for suicide and depression did not increase, despite a 40% increase in calls to the New York City crisis line during the blockade. The authors of the study warn that continued quarantine with the resulting economic turmoil could lead to a future increase in these questions.

Recognizing the limitations of Internet search trends, the authors of the study advocate providing competent online and telemedicine services during quarantine. “There is a possibility of the second wave [SARS-CoV-2] The return to the looming blockade needs to enable individuals searching the Internet to quickly obtain reliable information about strategies for dealing with distress and online help from authoritative sources, “the study authors said.

Studies have shown that the COVID-19 virus survives on the skin and hand hygiene is very effective.

SARS-CoV-2, the virus that causes COVID-19, is much longer than the influenza A virus (IAV) strain and survives 9 hours in human skin.Research Clinical infections Long survival on human skin has been shown to increase the risk of contact infection with SARS-CoV-2 compared to other viruses, but hand hygiene is very effective in neutralizing the virus. You can see that it is a target.

Contact infections are considered an important risk factor for the spread of COVID-19, highlighting the important need for information on the survival of the virus on the skin. Previous studies have confirmed that coronaviruses are more stable than other enveloped viruses such as IAV, which have a protective, fatty outer wrapping.

The stability of the virus on human skin is not well understood because of the risk of exposing subjects to pathogenic viruses. The authors of the study developed a model for testing viral stability using human skin obtained from autopsy specimens and measured viral viability of SARS-CoV-2 via droplets and contact infections. Compared to common strains of contagious IAV. They recorded the survival time of viral samples in human mucus and medium on various surfaces (human skin, stainless steel, glass, polystyrene plastic) and assessed the effectiveness of 80% ethanol for viral survival in human skin. Did.

Researchers have found that both types of viruses are inactivated faster on the skin than on other surfaces. This suggests that human skin is not a very friendly environment for viruses. However, the study also found that SARS-CoV-2 survived on skin significantly longer than IAV: 9.04 hours (95% confidence interval, 7.96 to 10.2 hours) vs. 1.82 hours (1.65-2.00 hours). ), High risk of contact infection with COVID-19.

In particular, the authors of the study also found that SARS-CoV-2 was completely inactivated within 15 seconds of exposure to 80% ethanol, the type of alcohol found in many commercial alcohol-based hand sanitizers. Discovered and emphasized the importance of proper hand sanitizers Hygiene for the prevention and dissemination of COVID-19. The US Centers for Disease Control and Prevention (CDC) recommends the use of 60% to 95% alcohol in COVID-19 hand sanitizers.

Summer family gatherings lead to COVID-19 outbreaks

Today’s survey Weekly morbidity and mortality reports (((MMWRThe outbreak of COVID-19 at a three-week family gathering that affected people in four states could have occurred from a 13-year-old girl who was exposed to an outbreak in June six days before arrival. I conclude that it is highly likely.

Fourteen relatives (including the first patient) stayed in a four-bedroom, two-furo home for eight to 25 days, and all but two were eventually infected. The other six visited outside physically for 10 hours on the 3rd day and 3 hours on the 10th day. None of the 20 people wore face masks, but more cautious relatives did not get COVID-19.

One of the infected relatives sought hospitalization and the other went to the emergency department due to respiratory problems. Both have recovered.

The first patient underwent a rapid SARS-CoV-2 antigen test 4 days after exposure before the family gathered, but returned negative. However, the authors of the report, who come from the CDC and the state and local health departments, probably intended that the test (the only type she could use at the time) would be used within the first five days of symptoms. It is said that it was because it was. , And she was asymptomatic. The only symptom she showed was a stuffy nose six days after exposure, which was also the beginning of a family gathering.

The authors state that this outbreak is yet another example of a viable COVID-19 vector in children and adolescents. The report also reiterated the importance of post-exposure quarantine, confirmed that the rapid antigen test was negative on the polymerase chain reaction test, and followed physical distance and mask guidelines, and distanced relatives were infected. It points out that there is no such thing.
