COVID-19: Media Group Calls For Increased Welfare For Journalists

Journalists

Media/civil society groups have demanded increased welfare of journalists during the outbreak of COVID-19.

The groups also called for special protection and support for journalists covering the outbreak of the virus in Nigeria.

The groups made the demand following a survey to assess the support available to journalists for their safety in covering the COVID-19 pandemic.

The Wole Soyinka Centre for Investigative Journalism, Enough is Enough, International Press Centre, the International Centre for Investigative Reporting, and Premium Times Centre for Investigative Journalism, commissioned the survey following perceptions that journalists were being exposed to danger in the course of covering the pandemic.

The survey, filed by 463 journalists — correspondents, reporters, editors, freelancers and presenters from 73 print, broadcast and online media across 33 states and the Federal Capital Territory – revealed that there has been a poor attention to the needs, safety and welfare of journalists covering the pandemic.

Drawing from responses from the survey, the media/civil society groups have urged media proprietors to ensure that reporters on the field are adequately insured and financially empowered as they urged media outfits owing salaries to immediately pay their journalists.

They also demanded that media organisations should, “Establish workplace policy and follow the same to equip their journalists with specialised and personal protective equipment including for observation of social distancing while on the field.

“Provide training to journalists on how to crowd source information for their stories without having to necessarily go to the field; and explore technological options for interviews while in-house infrastructure should be put in place to ensure the safety of employees and guests (particularly for broadcast media) in line with the safety advisory of the government and health authorities.”

They also enjoined freelance journalists to take advantage of reporting grants and other opportunities to procure personal protective equipment while covering the pandemic.

Following the outbreak, media outfits are beginning to introduce reduction in salaries, with organisations citing economic importance as reason for the deduction.

COVID-19: Ogun Extends Lockdown For One Week

Governor Dapo Abiodun of Ogun State has extended the lockdown in the state by another week.

The governor announced this on Friday while briefing journalists in the state.

The governor frowned at the flouting of social and safety guideline to ensure the eradication of the virus in the state.

He noted that the lockdown extension was a precautionary method, adding that residents must wear face masks.

He said, “Reports reaching us have shown that many of our people are showing utter disregard for the precautionary guidelines, international best practices and safety measures rolled out, especially, during the window of relaxation of the lockdown.

“We have heard and seen the havoc that COVID-19 continues to wreck in other lands. Let us learn from these experiences.

“Now, to preserve the lives of our people, we are persuaded to extend the currently modified lockdown, which has been slightly eased, for another one week alongside the current guidelines.

“Wearing a face mask is mandatory. It is important to note that we have provided, and continue to provide, facemasks to public servants, groups and association.”

Abiodun said the test had intensified its contact tracing and would continue to test and treat people suspected or infected with the virus.

He added, “As of today, we have screened over 10,000 people and tested over 700. In addition to that, we have intensified our contact tracing capacity and have traced over 551 contacts of the COVID-19 positive patients.

“We are doing this to detect and treat people who are already infected rather than leaving them undetected which will be more detrimental because this will increase community transmission.”

Sarawak’s second active Covid-19 detection operation covers 2,100 people

KUCHING: A Covid-19 case detection operation is being conducted in Kampung Tabuan Lot here today involving more than 2,100 people from 423 houses, said Sarawak State Disaster Management Committee (JPBN) chairman Datuk Amar Douglas Uggah Embas.

He said the operation, the second such exercise in Sarawak, was being undertaken from 8.30am to 5pm to screen the close contacts of Covid-19 positive patients.

“A (Covid-19) victim from the village had died while there was another case which could not be linked to any existing cluster. This programme was launched because the Covid-19 carriers might have unknowingly spread the virus to their families, neighbours and the community,” he told reporters after visiting the village today.

He said 171 personnel from the Sarawak Health Department, Royal Malaysia Police and Civil Defence Force are involved in the operation.

Fast and early detection of the deadly coronavirus was important because there were asymptomatic Covid-19 cases, he added.

A total of 15,583 people from 5,300 houses in Taman Desa Ilmu and Taman Uni Garden in Kota Samarahan were screened in the first case detection operation conducted from April 27 to May 3. — Bernama

Commemorating Smallpox Eradication – a legacy of hope, for COVID-19 and other diseases

On 8 May 1980, the 33rd World Health Assembly officially declared: ‘The world and all its peoples have won freedom from smallpox.’

The declaration marked the end of a disease that had plagued humanity for at least 3 000 years, killing 300 million people in the 20th century alone.

It was ended, thanks to a 10-year global effort, spearheaded by the World Health Organization, that involved thousands of health workers around the world to administer half a billion vaccinations to stamp out smallpox.

The US$ 300m price-tag to eradicate smallpox saves the world well over US$ 1 billion every year since 1980.

Speaking at a virtual event hosted at WHO-HQ, involving key players in the eradication effort, WHO Director-General, Dr Tedros Adhanom Ghebreyesus said, “As the world confronts the COVID-19 pandemic, humanity’s victory over smallpox is a reminder of what is possible when nations come together to fight a common health threat.”

The world got rid of smallpox thanks to an incredible demonstration of global solidarity, and because it had a safe and effective vaccine. Solidarity plus science equalled solution!

Dr Tedros highlighted that smallpox eradication also offers hope for efforts to eliminate other infectious diseases, including polio, which is now endemic in just two countries. To date, 187 countries, territories and areas have been certified free of Guinea worm disease, with seven more to go. And the fight against malaria has so far resulted in 38 countries and territories certified as malaria-free. In the case of Tuberculosis (TB), 57 countries and territories with low TB incidence are on track to reach TB elimination.

At the event, Dr Tedros unveiled a commemorative postal stamp to recognize the global solidarity that drove the initiative and honour the efforts of health workers who ensured its success.

The stamp, developed by the United Nations Postal Administration (UNPA), in collaboration with WHO, signifies what national unity and global solidary can achieve. Numerous countries, such as Guinea, India, Nigeria, Philippines, Togo and others issued smallpox stamps to show support for, and raise awareness about WHO’s Intensified Smallpox Eradication Programme launched in 1967.

WHO Regional Director for Africa, Dr Matshidiso Moeti’s earliest memories of smallpox is of her father. “I was visiting WHO headquarters, and I saw a photo of my Dad, standing with the other experts on the Global Commission. I remember him going out, doing follow-up visits with patients. He often would go with a driver and disappear into the bush for days. I felt in awe of his tireless work. The strategies used to eradicate smallpox still apply today.”

“Lessons learned from smallpox are used today to respond to disease outbreaks. For example, house-to-house active case-finding underpins the polio eradication programme, and ring vaccination of contacts is helping to combat the spread of the Ebola virus disease. Similarly, surveillance, case-finding, testing, contact-tracing, quarantine, and communication campaigns to dispel misinformation are central to controlling COVID-19, “ explained David Heymann, Professor of Infectious Disease Epidemiology at The London School of Hygiene & Tropical Medicine (LSHTM) and Distinguished Fellow, Global Health Security at Chatham House, London.

Following smallpox eradication, WHO and UNICEF launched the Expanded Programme on Immunization, under which 85% of the world’s children are vaccinated and protected from debilitating diseases.

With the potential of a COVID-19 vaccine ahead, ensuring sufficient supplies and reaching people in hard to reach places is a high priority. Addressing vaccine hesitancy poses a significant challenge to stop the virus. Access to accurate public health information and education is critical to ensure that the public has the facts to keep themselves and others safe.

To permanently commemorate the eradication of smallpox and the lessons learned on a global scale, rather than every 10-years, WHO is calling museums, exhibition companies, designers, curators and associations to develop an immersive, interactive and educational exhibition on smallpox and its relevance for COVID-19 and global health security. The exhibition, which will be unveiled later this year, will promote a better understanding of public health and empower people to keep informed and safe during a pandemic.

Notes to the media

Smallpox stamp

The smallpox stamp is in the denomination of CHF 1,70. It was designed by Sergio Baradat (United Nations) in collaboration with the World Health Organization and is available for purchase at unstamps.org. The stamp can be used to mail postcards and letters around the world, provided that they are sent from the UN headquarters in New York, Geneva or Vienna respectively.

Smallpox Eradication dates

On 9 December 1979, a global commission certified that smallpox had been eradicated, and this certification was officially accepted by the 33rd World Health Assembly in 1980.

Museum Exhibition

Exhibition design companies, museums, curators and other companies/organizations in this field are invited to express their interest to develop an immersive, educational exhibition on smallpox and its relevance for COVID-19 and global health security by writing to privatesectorpartners@who.int

Billions worldwide living with herpes

About half a billion people worldwide are living with genital herpes, and several billion have an oral herpes infection, new estimates show, highlighting the need to improve awareness and scale up services to prevent and treat herpes.

About 13% of the world’s population aged 15 to 49 years were living with herpes simplex virus type 2 (HSV-2) infection in 2016, the latest year for which data is available. HSV-2 is almost exclusively sexually transmitted, causing genital herpes. Infection can lead to recurring, often painful, genital sores in up to a third of people infected.

Herpes simplex virus type 1 (HSV-1) is mainly transmitted by oral to oral contact to cause oral herpes infection – sometimes leading to painful sores in or around the mouth (“cold sores”). However, HSV-1 can also be transmitted to the genital area through oral sex, causing genital herpes.

Around 67% of the world’s population aged 0 to 49 had HSV-1 infection in 2016 – an estimated 3.7 billion people. Most of these infections were oral; however, between 122 million to 192 million people were estimated to have genital HSV-1
infection.

Genital herpes is a substantial health concern worldwide – beyond the potential pain and discomfort suffered by people living with the infection, the associated social consequences can have a profound effect on sexual and reproductive
health” says Dr Ian Askew, Director of the Department of Sexual and Reproductive Health and Research at the World Health Organization (WHO).

Herpes and HIV

People with HSV-2 infection are at least three times more likely to become infected with HIV, if exposed. Thus, HSV-2 likely plays a substantial role in the spread of HIV globally. Women are more susceptible to both HSV-2 and HIV. Women living in
the WHO Africa Region have the highest HSV-2 prevalence and exposure to HIV – putting them at greatest risk of HIV infection.

No cure: vaccine needed

There is no cure for herpes. Antiviral medications, such as acyclovir, famciclovir, and valacyclovir, can help to reduce the severity and frequency of symptoms but cannot cure the infection.

Better awareness, improved access to antiviral medications and heightened HIV prevention efforts for those with genital HSV symptoms are needed globally. In addition, development of better treatment and prevention interventions is needed, particularly
HSV vaccines.

“A vaccine against HSV infection would not only help to promote and protect the health and well-being of millions of people, particularly women, worldwide – it could also potentially have an impact on slowing the spread of HIV, if developed
and provided alongside other HIV prevention strategies” says Dr Meg Doherty, Director of the WHO Department of Global HIV, Hepatitis, and STI Programmes.

Authored by staff at the University of Bristol, the WHO, and Weill Cornell Medical College-Qatar, and published in the Bulletin of the World Health Organization, this new study estimates the global infection prevalence and incidence of HSV-1 and HSV-2
in 2016.

Statement on the third meeting of the International Health Regulations (2005) Emergency Committee regarding the outbreak of coronavirus disease (COVID-19)
The third meeting of the Emergency Committee convened by the WHO Director-General under the International Health Regulations (2005) (IHR) regarding the coronavirus disease (COVID-19), took place on Thursday, 30 April 2020, from 12:00 to 17:45 Geneva
time (CEST).

Proceedings of the meeting

Members and advisors of the Emergency Committee were convened by teleconference. Membership of the Emergency Committee was expanded
to reflect the nature of the pandemic and the need to include additional areas of expertise.

The Director-General welcomed the Committee, thanked them for their commitment to enhancing global public health, and provided an overview of the major achievements in the COVID-19 response since the last Emergency Committee meeting on 30 January 2020.
Representatives of the legal department and the Department of Compliance, Risk Management, and Ethics (CRE) briefed the members on their roles and responsibilities.

The Ethics Officer from CRE provided the members and advisers with an overview of the WHO Declaration of Interest process. The members and advisers were made aware of their individual responsibility to disclose to WHO, in a timely manner, any interests
of a personal, professional, financial, intellectual or commercial nature that may give rise to a perceived or direct conflict of interest. They were additionally reminded of their duty to maintain the confidentiality of the meeting discussions and
the work of the committee. Only those committee members and advisers who were not considered to have any perceived or direct conflict of interest participated in the meeting.

The Secretariat turned the meeting over to the Chair, Professor Houssin. He also welcomed the Committee and reviewed the objectives and agenda of the meeting.

The WHO Regional Emergency Directors and the Executive Director of the WHO Health Emergencies Programme (WHE) provided regional and the global situation overview. After ensuing discussion, the Committee unanimously agreed that the outbreak still constitutes
a public health emergency of international concern (PHEIC) and offered advice to the Director-General.

The Director-General declared that the outbreak of COVID-19 continues to constitute a PHEIC. He accepted the advice of the Committee to WHO and issued the Committee’s advice to States Parties as Temporary Recommendations under the IHR.

The Emergency Committee will be reconvened within three months or earlier, at the discretion of the Director-General. The Director-General thanked the Committee for its work.

Massive proportion of world’s population are living with herpes infection

Virus causing genital herpes may put millions of people at greater risk of infection with HIV

About half a billion people worldwide are living with genital herpes, and several billion have an oral herpes infection, new estimates show.

Authored by staff at the University of Bristol, World Health Organization (WHO), and Weill Cornell Medical College-Qatar, and published in the Bulletin of the World Health Organization,
the new study estimates the global infection prevalence and incidence of herpes simplex virus types 1 and 2 (HSV-1 and HSV-2) in 2016.

“Herpes infection affects millions of people across the globe and can have far-reaching health effects. We need more investment and commitment to develop better treatment and prevention tools for this infection.” says Dr Sami Gottlieb, Medical
Officer at WHO and an author of the study.

Prevalence and incidence

An estimated 491.5 million people were living with HSV-2 infection in 2016, equivalent to 13.2% of the world’s population aged 15 to 49 years. HSV-2 is almost exclusively sexually transmitted, causing infection in the genital or anal area (genital
herpes).

An estimated 3.7 billion people had HSV-1 infection during the same year – around 66.6% of the world’s population aged 0 to 49. HSV-1 is mainly transmitted by oral to oral contact to cause infection in or around the mouth (oral herpes). However,
HSV-1 can also be transmitted to the genital area through oral-genital contact – during oral sex – to cause genital herpes. Most HSV-1 infections were oral; however, between 122 million to 192 million people were estimated to have genital
HSV-1 infection, depending on the assumptions used in the estimation model.

Because herpes is a lifelong infection, estimated prevalence increased with age; HSV-2 prevalence was also higher among women and in the WHO African Region.

Health and social impacts

Most people living with herpes, caused by either HSV-1 or 2, are unaware they have the infection.

When symptoms do occur however, oral herpes infection can lead to painful sores around the mouth (“cold sores”). Genital herpes infection can cause recurring, often painful, genital sores, often referred to as genital ulcer disease.

WHO and partners published a study in March 2020 estimating that around 5% of the world’s population (187 million people) suffered from at least one episode of herpes-related genital ulcer disease in 2016 (1). Most of these episodes were due to
HSV-2, which can recur frequently over many years.

Recurrent symptoms of genital herpes can lead to stigma and psychological distress, and can have an important impact on quality of life and sexual relationships. However, in time, most people with herpes adjust to living with the infection.

“Genital herpes is a substantial health concern worldwide – beyond the potential pain and discomfort suffered by people living with the infection, the associated social consequences can have a profound effect on sexual and reproductive health”
says Dr Ian Askew, Director of the Department of Sexual and Reproductive Health and Research at WHO.

Herpes and HIV

A strong association exists between HSV-2 infection and HIV infection. In 2019, WHO commissioned a modeling study to estimate how much HSV-2 infection might contribute to HIV incidence. The study estimated that almost 30% of new sexually acquired HIV
infections in 2016 worldwide were likely attributable to HSV-2 infection (2).

Evidence shows that people with HSV-2 infection are at least three times more likely to become infected with HIV, if exposed. HSV-2 leads to inflammation and small breaks in the genital and anal skin that can make it easier for HIV to cause infection.
In addition, people with both HIV and HSV-2 infection are more likely to spread HIV to others.

Women have higher biologic susceptibility to both HSV-2 and HIV. Women living in the WHO Africa Region have the highest HSV-2 prevalence and exposure to HIV – putting them at greatest risk of HIV infection, with negative implications for their health
and well-being.

For people living with HIV (or who are living with other conditions that compromise their immune systems) as well as HSV-2, the symptoms of herpes can be more severe and more frequent.

Neonatal herpes

Neonatal herpes can occur when an infant is exposed to HSV in the genital tract during delivery. This is a rare condition, occurring in an estimated 10 out of every 100,000 births globally, but can lead to lasting neurologic disability or death. The risk
for neonatal herpes is greatest when a mother acquires HSV infection for the first time in late pregnancy. Women who have genital herpes before they become pregnant are at very low risk of transmitting HSV to their infants.

No cure – better treatment and prevention needed

There is no cure for herpes. At present, antiviral medications, such as acyclovir, famciclovir, and valacyclovir, can help to reduce the severity and frequency of symptoms but cannot cure the infection.

As well as increasing awareness about HSV infection and its symptoms, improved access to antiviral medications and heightened HIV prevention efforts for those with genital HSV symptoms are needed globally.

In addition, development of better treatment and prevention interventions is needed, particularly HSV vaccines. WHO and partners are working to accelerate research to develop new strategies for prevention and control of HSV infections. Such research includes
the development of HSV vaccines and topical microbicides. Several candidate vaccines and microbicides are currently being studied.

“A vaccine against HSV infection would not only help to promote and protect the health and well-being of millions of people, particularly women, worldwide – it could also potentially have an impact on slowing the spread of HIV, if developed
and provided alongside other HIV prevention strategies” says Dr Meg Doherty, Director of the WHO Department of Global HIV, Hepatitis, and STI Programmes.
