The Coronavirus Can Be Airborne Indoors, W.H.O. Says



"We have been talking about the possibility of airborne transmission and aerosol transmission as one of the modes of transmission of COVID-19," Maria Van Kerkhove, technical lead on the COVID-19 pandemic at the WHO, told a news briefing."





  • The World Health Organization has acknowledged that there's possibility of coronavirus being spread in the air under certain conditons

  • The UN body releases new guidelines on COVID-19 transmission, including new scientific evidence available on the spread of the SARS-CoV-2





The coronavirus may linger in the air in crowded indoor spaces, spreading from one person to the next, the World Health Organization acknowledged on Thursday.




The W.H.O. had described this form of transmission as doubtful and a problem mostly in medical procedures. But growing scientific and anecdotal evidence suggest this route may be important in spreading the virus, and this week more than 200 scientists urged the agency to revisit the research and revise its position.




In an updated scientific brief, the agency also asserted more directly than it had in the past that the virus may be spread by people who do not have symptoms: “Infected people can transmit the virus both when they have symptoms and when they don’t have symptoms,” the agency said.




The W.H.O. previously said asymptomatic transmission, while it may occur, was probably “very rare.” Some experts said both revisions were long overdue, and not as extensive as they had hoped.




“It is refreshing to see that W.H.O. is now acknowledging that airborne transmission may occur, although it is clear that the evidence must clear a higher bar for this route compared to others,” Linsey Marr, an aerosol expert at Virginia Tech, said in an email.




An aerosol is a respiratory droplet so small it may linger in the air. In its latest description of how the virus is spread, the agency said transmission of the virus by aerosols may have been responsible for “outbreaks of Covid-19 reported in some closed settings, such as restaurants, nightclubs, places of worship or places of work where people may be shouting, talking or singing."



The guidelines stated that understanding how, when and in what types of settings the SARS-CoV-2 virus spreads between people is critical for developing effective public health and infection prevention measures to break chains of transmission. WHO said current evidence suggests that COVID-19 transmission occurs primarily through direct, indirect, or close contact with infected individuals through their saliva and respiratory secretions, or through their respiratory droplets expelled when they cough, sneeze, talk or sing. The agency also said that asymptomatic people can also spread the virus to others, although it is still unclear to what extent this occurs and more research is needed in this area.



WHO stressed that high-quality research is urgently needed to understand the role of airborne spread of the SARS-CoV-2 transmission in the absence of aerosol-generating procedures, the dose of virus required for transmission to occur, the settings and risk factors for superspreading events, as well as the extent of asymptomatic and pre-symptomatic transmission. In this article, let us tell you how airborne transmission is different from droplet transmission and what you can do to stay safe from respiratory infections such as COVID-19.



What you can do to prevent contracting respiratory infections?

In the current scenario,





  • it’s always best to wear a mask while venturing out in crowded areas to keep respiratory infections away.

  • Try to keep at least 3 feet physical distance and wash hands frequently with soap and water for at least 20 seconds.

  • Do not touch your face unnecessarily.

  • Practice respiratory etiquette.

  • Avoid crowded places, close-contact settings and confined and enclosed spaces with poor ventilation.

  • Ensure appropriate environmental cleaning and disinfection.

  • To maintain immunity, opt for Indian square meal and exercises like Surya Namaskar and Pranayam or any other cardiorespiratory fitness regimen. It can help your cardio-respiratory fitness and lowers blood pressure as well. Moreover, it also increases cardio-respiratory efficiency and respiratory capacity.

  • To prevent transmission, WHO recommends identifying suspect cases as quickly as possible, testing, and isolating all cases (infected people) in appropriate facilities.

 “The world could learn from Taiwan’s success in responding to the coronavirus pandemic, yet it doesn’t have a seat at the World Health Organization.”

On Monday, May 18, representatives of 194 countries gathered virtually for one of the most important public health meetings in recent memory. A country thought to have had one of the best public health responses to the coronavirus pandemic—Taiwan was not invited. 
Taiwan attended the assembly as an observer from 2009 to 2016 but China blocked further participation after the election of Taiwan President Tsai Ing-wen, whom China views as a separatist, an accusation she rejects. 
Taiwan is not a member of the WHO as China has opposed its entry into international bodies. Taiwan was the first to begin screening passengers from Wuhan, starting December 31. 
Taiwan is not a member of the United Nations (UN) or its sub-organizations, but it aspires to participate. China also claims Taiwan as part of its territory and denies that Taiwan is a sovereign state. China is adamant about preventing recognition of Taiwan as a sovereign state and its membership in the UN system. Like other U.N. organizations, the WHO considers Taiwan a part of the People’s Republic of China and excludes its government from membership. This, critics say, is detrimental to global cooperation during the COVID-19 pandemic, during which Taiwan has emerged as one of the most effective countries in combating the disease. Taiwan and its defenders have strongly criticized the WHO and its director-general, Tedros Adhanom Ghebreyesus, for being overly deferential to Beijing.
 China, officially called the People’s Republic of China (PRC), refuses to allow that to happen. The PRC claims that Taiwan is a province of China, not an independent state. It says that only the PRC has the right to represent all of China in the United Nations and other international organizations, including the WHO, that limit membership to states. Taiwan’s government, generally called the Republic of China on Taiwan, has all the elements of statehood required by international law and maintains diplomatic relations with fifteen countries. Yet due to the PRC’s great-power status, including its seat as a permanent UN Security Council member, Beijing has been able to impose its “One China” policy upon the world.
 
In the early days of the outbreak, health officials in Taipei say the WHO ignored their warnings—based on communication with mainland colleagues—that the disease could be transmitted between humans, slowing the global response to the growing threat. Instead, in mid-January, the organization issued a now-infamous endorsement of China’s finding that there was no human-to-human transmission of the novel coronavirus in Wuhan. The WHO continued to praise China’s handling of the virus throughout January, despite abundant evidence that authorities were covering up the severity of the situation in Wuhan. This praise was especially stark in contrast to the organization’s criticism of China during SARS. Taiwan has had remarkable success in combating the virus. More than two months after COVID-19 arrived on the island, it has seen only 380 cases and five deaths. Yet its health officials remain frozen out of emergency meetings and briefings at the main organization coordinating the global response to the pandemic. (In a painfully awkward interview with a Hong Kong journalist, one senior WHO official seemed to pretend not to hear the question and then insisted on moving on when asked about Taiwan.)

Why is Taiwan’s exclusion a problem, especially during the coronavirus pandemic?


Taiwan is an important stakeholder and a valuable partner in fighting this unprecedented crisis. Taiwan’s government is donating masks to countries in need and sharing its experience using technology to investigate outbreaks. It is also working with U.S. experts to develop more rapid diagnostic test kits and vaccines.
Despite Taiwan’s valuable input, the WHO continues to shun it. For example, when asked by a journalist about Taiwan’s exclusion and experience dealing with the pandemic during a recent interview, WHO senior advisor Bruce Aylward hung up the call after trying to avoid the questions. After this public relations disaster, the WHO claimed it was closely working with Taiwan experts, which Taiwan’s government refuted. Taiwan has continually shared coronavirus data with the WHO, but the WHO has never released this information to its members. Additionally, in a February coronavirus status report, the WHO misreported the number of cases in Taiwan based on information provided by China. It also continues to deceptively list Taiwan’s case numbers under China’s. Taiwan was snubbed by the WHO yet again when it was not invited to the organization’s emergency meetings in January. After repeated requests, in February, the WHO finally allowed two Taiwanese experts to attend an online forum. Such ludicrous limitations have rightly been scoffed at by many governments and critics.
The WHO’s exclusion of Taiwan from the global fight against the pandemic is a reckless dereliction of duty. WHO Director-General Tedros Adhanom Ghebreyesus, whose election was due in large part to China’s support, has been widely criticized for actions that appeared to help China downplay the outbreak, delaying the international response as a result. Taiwan’s exclusion is an example of how the world’s health body puts politics before public health. Governments and concerned citizens must demand that the WHO fulfill its obligation—to represent the world’s health interests, not China’s—and hold the WHO accountable when it fails.
Wu said that Taiwan had agreed the issue of its participation would be put off until later in the year so the shorted assembly can focus on the coronavirus.
"Understandably, countries want to use the limited time available to concentrate on ways of containing the pandemic," he said.
"For this reason, like-minded nations and diplomatic allies have suggested that the proposal be taken up later this year when meetings will be conducted normally, to make sure there will be a full and open discussion," Wu added.


U.S AND TAIWAN


The United States has attempted to maximize Taiwan’s involvement in international relations and has, without success, supported Taiwan’s “meaningful participation” in various institutions, including the World Health Assembly (WHA), the WHO’s highest decision-making body. In March 2020, the Donald J. Trump administration enacted the Taiwan Allies International Protection and Enhancement Initiative Act, aimed at supporting Taiwan’s international presence. U.S. Secretary of State Mike Pompeo said that the State Department would “do [its] best to assist” Taiwan’s “appropriate role” in the WHO.
 Nearly 15 countries, including Belize, Guatemala, the Marshall Islands,, and Honduras, had written to the director-general of WHO, Tedros Adhanom Ghebreyesus, asking that the question of Taiwan's participation be added to the agenda.
But on Monday Taiwan's foreign minister Joseph Wu said "countries want to use the limited time available to concentrate on ways of containing the pandemic".

"We have accepted the suggestion from our allies and like-minded nations to wait until the resumed session before further promoting our bid," Wu said. He added that allies had suggested instead the proposal be taken up later in the year when the WHO is expected to hold in-person meetings. The calls for Taiwan to join the meetings had angered Beijing.
