Two Connecticut residents died over the summer due to infections linked to bacteria found in raw shellfish or seawater, health officials said Tuesday. The state Department of Public Health said that three people there are known to have been infected with the Vibrio vulnificus bacteria. However, the state Bureau of Aquaculture said earlier this month that Connecticut shellfish have never been associated with such infections and that the bureau tests commercial oysters statewide and has not detected it in any samples. Two of the three cases were wound infections not associated with seafood. The third was in a Connecticut resident who consumed raw oysters not harvested from Long Island Sound at an out-of-state establishment. NEW COVID SUBVARIANT, ERIS, IS NOW MOST COMMON AND FASTEST-SPREADING IN US: ‘NEVER GOING AWAY’ Two Connecticut residents have died this summer from infections linked to bacteria found in raw shellfish, the state Department of Public Health said Tuesday, Aug. 15, 2023. (AP Photo/Mark Lennihan) All three were between the ages of 60 and 80. The two deaths occurred in July, and the health department said it was the first time Connecticut has seen a Vibrio case in three years. Five cases were reported there in 2020. Vibrio vulnificus has never been found in state waters, it noted, with the majority of infections linked to shellfish from much warmer waters. Nearly a decade ago, the state added requirements to cool oysters to the point where such bacteria cannot survive. Vibrio vulnificus can cause life-threatening wound infections.

For lower-risk areas, harvesters must refrigerate or ice all oysters within five hours of harvest. Notably, the bacterium does not make an oyster look, smell or taste any different from usual. Infections can result in severe illness, including bloodstream infections. It can also cause wound infections, and people who become infected can get seriously ill and need intensive care or limb amputation. Vibriosis causes an estimated 80,000 illnesses and 100 deaths in the United States every year, according to the Centers for Disease Control and Prevention.

Researchers looked at the ability of canines to recognise the virus and its variants, even when they are obscured by other viruses, like those from common colds and flu. More than 400 scientists from over 30 countries contributed to the study as well as 147 scent dogs, according to the findings published in the Journal of Osteopathic Medicine. After analysing many studies covering both field and clinical experiments, Professor Dickey and Junqueira found that dogs who are trained to sniff out scents are “as effective and often more effective” than antigen tests. A total of 53 dogs were trained to sniff out Covid scents, while 37 were not and scientists found that the dogs that were not trained were in some cases “slightly superior” to those that were pre-trained. “The previously untrained dogs have the advantage that they are not as prone to indicating on scents other than the Covid–19 associated scent,” the paper said. The results indicated that not only can dogs detect Covid faster, but they can also do so in a non-intrusive manner. This means you won’t need to put a swab in your throat or nose. How can dogs detect the virus? This essentially comes down to the dog’s highly evolved nose with its ability to sense out smells quicker. Dogs possess up to 300 million olfactory receptors in their noses, compared to about six million in humans. And the part of a dog’s brain that is devoted to analysing smells is about “40 times greater” than humans. Canines also have ‘neophilia’, which means they are attracted to new and interesting odours And so, with all these enhancements, dogs can detect very low concentrations of odours associated with Covid infections. “They can detect the equivalent of one drop of an odorous substance in 10.5 Olympic-sized swimming pools,” Professor Dickey said. “For perspective, this is about three orders of magnitude better than with scientific instrumentation.” Scientists also found that in some cases, the animals were also able to detect the virus in pre-symptomatic and asymptomatic patients, “whose viral load was too low for conventional tests to work.” Professor Dickey has said that dogs can also differentiate Covid and its different variants in the presence of other respiratory viruses. This included the common cold or flu. “They’re much more effective. In fact, one of the authors that we quote in the paper commented that the RT-PCR test is not the gold standard anymore. It’s the dog. And they’re so quick,” he added. “They can give you the yes or no within seconds if they’re directly smelling you.” How was the study conducted to see if dogs can really detect Covid-19? In some studies, the dogs gave a person a quick sniff, sitting down to see if the person has Covid. In another study, the dog was given a sweat sample to smell for a few minutes. The press release has said that scent dogs, such as beagles, basset hounds and coonhounds are the ideal candidates for sniffing out the virus, given their “natural tendencies to rely on odours to relate to the world.” But the studies which the researchers analysed showed a variety of dogs were up for the challenge and were able to sniff out the Covid odour. With a few weeks of training, puppies, older dogs, purebred and mixed breeds, both male and female were able to sniff such odours out and “all performed admirably,” the Eureka Alert press release said. Although there has been success with dogs detecting such viruses, researchers believe there are still many challenges with using dogs for medical diagnoses. “There’s quite a bit of research, but it’s still considered by many as a kind of a curiosity,” said Professor Dickey. In conclusion, Professor Dickey and Junqueira said after reviewing the studies, believe that scent dogs deserve “their place as a serious diagnostic methodology that could be particularly useful during future pandemics, potentially as part of rapid routine health screenings in public spaces.” “Perhaps, most importantly, we argue that the impressive international quality and quantity of COVID scent dog research described in our paper for the first time, demonstrates that medical scent dogs are finally ready for a host of mainstream medical applications,” they added.

Monsoon season can add to your health woes as the season is known to weaken immunity and raise risk of illnesses and infections. As per studies, one’s chances of getting microbial infections goes up manifold in monsoon owing to humid weather conditions and temperature fluctuations. This year, many parts of the country received excess rainfall due to which diseases caused by virus, bacteria, fungus are seeing an exponential rise. Viral infections from dengue, malaria to influenza and common cold, gastro-intestinal diseases, hepatitis, conjunctivitis are fast spreading in the recent months. (Also read: Want better immunity? Check out this recommended diet for monsoon) Increased viral activity during the monsoon season often leads to the prevalence of viral fevers. “Increased viral activity during the monsoon season often leads to the prevalence of viral fevers. Some of the viral infections that are prevalent in monsoon seasons and can be easily prevented by taking precautions,” says Dr. Ramniwas Gupta, Senior Consultant, Dept of Internal Medicine, Amrita Hospital, Faridabad. 1. Dengue fever Transmitted by mosquitoes, dengue can cause high fever, severe body pain, and even life-threatening complications. “Spread by the Aedes mosquito, dengue fever manifests with an abrupt onset of high fever, intense joint and muscle discomfort, headache, and a rash. In severe cases, it can lead to dengue haemorrhagic fever or dengue shock syndrome, causing bleeding, organ damage, and even death,” says Dr Gupta. 2. Malaria Malaria is another mosquito-borne disease that can lead to fever, chills, and body aches. Proper mosquito protection is crucial. It is important to wear long sleeved clothes that cover the body completely and take measures to control mosquito breeding, says Dr. Saibal Chakravorty, Senior Consultant – Internal Medicine, Metro Hospitals & Heart Institute, Noida Sector-11, UP shares common viral infections that are rampant in monsoon. 2. Chikungunya Also transmitted by Aedes mosquitoes, chikungunya causes fever, joint pain, muscle pain, headache, and rash. While fatalities are rare, the joint pain can be quite debilitating and persist for months, affecting the quality of life, says Dr Gupta. 4. Influenza (Flu) Flu viruses thrive in damp weather. Symptoms include fever, cough, fatigue, and body aches. Vaccination is a key preventive measure, says Dr Chakravorty. It can lead to pneumonia and other respiratory complications, particularly in vulnerable populations, says Dr Gupta. 5. Common Cold “Caused by various viruses, colds lead to a runny nose, cough, sneezing, and mild fever. Hygiene and avoiding close contact can help prevent it,” adds Dr Chakravorty. 6. Viral Gastroenteritis “Also known as stomach flu, it causes vomiting, diarrhoea, and abdominal pain. Staying hydrated is important,” says Dr Chakravorty. “Several different viruses, including rotavirus, norovirus, and adenovirus, account for most cases of acute viral gastroenteritis (loose motions and vomiting). The majority are spread through the faecal-oral route, which includes contaminated food and water,” says Dr Gupta. 7. Hand, Foot, and Mouth Disease Mostly affecting children, this viral infection causes sores in the mouth, hands, and feet. It spreads easily in crowded places, says Dr Chakravorty. 8. Hepatitis A & E These viral infections primarily spread through contaminated food and water. Symptoms encompass jaundice (yellowing of the skin and eyes), tiredness, abdominal discomfort, queasiness, and retching. Hepatitis A & E are usually self-limiting but can cause severe illness in some cases, says Dr Gupta. 9. Viral Conjunctivitis (Eye Flu) Viral conjunctivitis is highly contagious and is usually caused by adenovirus. Symptoms include eye irritation, photophobia, and watery discharge. Practice good eye hygiene and avoid using contact lenses. Viral conjunctivitis is self-limiting, lasting 1 week in mild cases to up to 3 weeks in severe cases. For symptomatic relief, apply cool compresses, says Dr Gupta. 10. Chickenpox “The varicella-zoster virus (VZV) causes chickenpox, a highly contagious illness. Other symptoms include an itchy, blister-like rash. The rash begins on the chest, back, and face before spreading across the entire body,” says Dr Gupta. Viral infections: Prevention and treatment Dr Gupta shares some prevention and treatment suggestions for the viral infections that tend to spread during the monsoon season in India: Stay hydrated: Staying well-hydrated is crucial for most viral infections to aid in recovery and manage symptoms. Rest: Get plenty of rest to help your body recover and build up its immune response. Pain and fever relief: Over-the-counter pain relievers and fever reducers (such as acetaminophen or paracetamol) can help manage symptoms. Always follow the recommended dosage. Medical attention: Seek medical help if symptoms worsen or if you experience severe symptoms. This is especially important for conditions like dengue, where early intervention can prevent complications. Hygiene: Isolate yourself to prevent the spread of infections to others. Practice good respiratory hygiene by covering your mouth and nose when sneezing or coughing. Vaccination: If available, consider getting vaccinated against diseases like hepatitis A, chickenpox, and influenza to prevent infection. Remember that self-medication is not recommended. Consult a medical professional for accurate diagnosis and appropriate treatment, especially for severe or persistent symptoms. Topics Monsoon Dengue Malaria
