Scientists in South Africa say they have detected a new variant of COVID-19.
The country's National Institute for Communicable Diseases announced Monday in a new study that the variant, which has been designated C.1.2, was first detected in South Africa in May of this year, and has since spread to seven other countries in Africa, Asia, Europe and the southern Pacific region of Oceania.
The scientists say the C.1.2 variant appears to have the same characteristics as that of other mutations that are more transmissible and more able to overtake a person's immune system.
The study has not been published nor has it undergone the normal peer review process. The scientists say they are still monitoring the frequency of the C.1.2 variant, and that it has not evolved as either a "variant of interest" or "variant of concern" under the guidelines established by the World Health Organization.

The U.S. Centers for Disease Control and Prevention said Monday that the three COVID-19 vaccines currently in use in the United States remain highly effective in preventing severe disease. Dr. Sara Oliver, a CDC scientist, told a vaccine advisory panel that the COVID-19 vaccine was 94% effective in preventing hospitalization for adults between the ages of 18 to 74 between April and July, when the delta variant became dominant.
The vaccine's effectiveness against hospitalization dropped among adults 75 and older, but was still above 80%.
Dr. Oliver told the panel the vaccines appear to be less effective in preventing infection or mild illness, which she said was due to the vaccine's weakening over time and the more contagious delta variant.

The advisory committee is considering whether to recommend authorizing booster shots of the Pfizer, Moderna or Johnson & Johnson vaccines amid a surge of new COVID-19 infections across the United States. The Biden administration recently announced it will begin offering a third shot of the Pfizer or Moderna vaccine sometime next month. Both the CDC and the Food and Drug Administration have recently recommended a third shot of Pfizer or Moderna for some people with weakened immune systems.
The committee unanimously voted Monday to recommend the Pfizer vaccine for Americans 16 years old and older.
In a separate development Monday, the CDC added seven new destinations to its highest risk level of its COVID-19 travel advisory list.
Azerbaijan, Estonia, Guam, North Macedonia, the U.S. territory of Puerto Rico, the Caribbean island nation of Saint Lucia and Switzerland have been designated as Level 4, which signifies a "very high" risk of contracting COVID-19. The CDC says people should avoid travel to these destinations, and advises that anyone who must travel to these spots needs to be fully vaccinated.

In New Zealand, health officials Tuesday reported another decline in new COVID-19 cases since Prime Minister Jacinda Ardern placed the country under a strict lockdown earlier this month. The health ministry posted 49 new cases on Tuesday, after reporting 53 cases Monday and 83 new cases Sunday.
Ardern imposed the strict lockdown on August 17 after a 58-year-old man in Auckland became the first person to test positive for COVID-19 since February. About 612 new cases have since been posted, with Auckland posting 597 and 15 detected in the capital, Wellington, according to Reuters. (VOA/RN)

The Supreme Court on Tuesday agreed to examine a seeking direction to the Election Commission to de-register a political party, which fails to comply with the court's direction to disclose criminal antecedents of candidates fielded in polls. Advocate Ashwini Upadhyay requested a bench headed by Chief Justice N.V. Ramana and comprising Justices A.S. Bopanna and Hima Kohli to list the petition urgently, against the backdrop of the ongoing election process. He contended that nomination for the first phase of the Uttar Pradesh Assembly election has started, and the political parties and candidates are brazenly violating the top court judgments.
After briefly hearing Upadhyay, the bench said: "We will consider it... will give a date".

The plea claimed that the cause of action for filing the plea arose after the Samajwadi Party fielded alleged gangster Nahid Hasan from Kairana but neither published his criminal records in electronic, print and social media nor the reason for his selection within 48 hours. On February 13, last year, Shamli police imposed the Gangster Act on Nahid Hasan, who is a two-time MLA from Kairana. "He (Hasan) has multiple criminal cases and is the 'mastermind' behind the Hindu exodus from Kairana. There are many criminal cases including fraud and extortion, and he was declared a fugitive by Special MLA-MP Court," the plea said.
The plea argued that the consequences of permitting criminals to contest and become legislators are extremely serious for democracy and secularism. The plea sought a direction to the Election Commission to take steps to ensure that every political party publishes the details regarding criminal cases of each candidate along with the reason for such selection on the homepage of its official website in bold letters within 48 hours in the spirit of top court orders passed on September 25, 2018, and February 2, 2020.

There will be no chief guest at the Republic Day parade this year also as the plan to host state heads of five Central Asian countries -- Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan -- seems to have been cancelled due to the Covid situation in India as well as in the respective nations. Though the Ministry of External Affairs is yet to confirm this officially.
If the guests arrive, then this would be the second time when India hosts a group of state heads as the chief guests on the Republic Day. In 2018, state heads of ASEAN countries graced the occasion with their presence. Apart from Kazakhstan, none of these countries' state heads had been invited as the chief guests on the Republic Day. In 2009, Kazakhstan's then president Nursultan Nazarbayev was the Chief Guest.

As per sources, due to the corona situation, the Government of India is in no mood to take any risk to invite any foreign guest, so the plan seems to have been cancelled. Last year, British Prime minister Boris Johnson was invited for the same, but later cancelled due to rising corona cases in the UK.
In the past, there have been occasions when the Republic Day ceremony was celebrated without any foreign guest. In 1966, there was no foreign chief guest in the Republic Day parade ceremony as the then Prime Minister Lal Bahadur Shastri had passed away in Tashkent in January, and Indira Gandhi took oath as Prime Minister on January 24.

A team of scientists from the Banaras Hindu University (BHU) have found a cure for those suffering from chronic wounds, particularly with diabetic foot ulcers. The team led by Prof Gopal Nath of the department of Microbiology, Institute of Medical Sciences, said that wounds that took months and years to heal, could now be cured in days or months. The findings of study have been published in the National Centre for Biotechnology Information, National Institutes of Health, US.
Prof Nath said that a wound is defined as a breach in the skin or body tissues due to injury. An acute wound is defined as a "recent break that is yet to progress through sequential stages of healing". The wounds where normal healing process is stalled due to underlying pathology (vascular and diabetes) or infection beyond three months is defined as chronic wound. While chronic wounds always get infected, the contaminated wounds are reasonably susceptible to infection.

Infection with antibiotic-resistant bacteria and biofilm formation halt healing progress. These wounds cause significant psychological and physical morbidity. The traditional treatment strategies often succeed in healing wounds, he said adding that many wounds have been observed recalcitrant to them, leading to persistence and recurrent infections. Search for alternatives to antibiotics has now become a compulsion. Fortunately, bacteriophage therapy is a re-emerging solution to antibiotic-resistant bacteria.
Prof Nath's team carried out phage therapy of acute and chronic infected wounds in animals and clinical studies. It showed efficacy against Pseudomonas aeruginosa in a mice wound model. Furthermore, they evaluated the efficacy of phage cocktails in animal models' acute and chronic osteomyelitis caused by methicillin-resistant Staphylococcus aureus. They also observed biofilm eradication from K wire in rabbits' wound infection model. Clinical trials of phage therapy initiated by the BHU have reported the efficacy of topical phage in healing chronic wounds in three prospective exploratory studies and no adverse events mimicking the results in vivo animal models.

A clinical study by Gupta demonstrated the significant role of bacteriophage therapy in the chronic wounds associated with antibiotic-resistant bacteria. The study employed a total of twenty patients with chronic non-healing ulcers for more than six weeks duration. A significant improvement could be achieved in the form of complete wound epithelization within a few weeks. Another study, employing 48 patients having a minimum of one eligible full-thickness wound that did not heal in six weeks with convention wound management, showed the promising result, and significant improvement was observed in the wound healing.
The study projected that specific phage therapy is equally effective regardless of the diabetic or non-diabetic status of the patient though the healing was relatively delayed in diabetic patients. Another successful study has shown encouraging results on healing process of infected acute traumatic wounds. The average number of days required for complete granulation of wounds and attaining sterility and healing was half compared to conventional therapy. (IANS/SP)
