 MALAYSIA recorded 6,976 new Covid-19 cases on May 23, the highest number of daily cases reported since the start of the pandemic in March 2020. The number of Covid-19 deaths and severe cases that require intensive care has also increased tremendously.

According to Health Ministry statistics, from May 1 to 21, Malaysia lost 643 people, close to one-third of all Covid-19 deaths in the country since the pandemic started. Within the same period, patients admitted to ICUs increased by 91% (from 337 to 643) and patients requiring ventilation support doubled from 176 to 363.

Covid-19 has negatively impacted the care of patients with noncommunicable diseases such as hypertension and diabetes. Hypertension (high blood pressure) is the most common pre-existing medical condition among Covid-19 patients globally as well as in Malaysia. Patients with hypertension are 95% more likely to require ICU admission and 160% more likely to succumb to the disease. A local study reported that 49% of patients with the severe form of Covid-19 had hypertension, compared with 13% among mild cases. The high prevalence of hypertension in Malaysia – three in every 10 adults have it – means that a substantial proportion of our adult population is at risk.

Adherence to and compliance with medication is crucial. Stop-ping antihypertensive medications could lead to poor blood pressure control, which in turn can result in adverse cardiovascular events such as heart attack, stroke, or kidney failure. All these are linked to poor Covid-19 outcomes.

In addition, once the virus enters the body, it could lead to overactivation of the immune system resulting in a cytokine storm, further burdening a cardiovascular and respiratory system that is already in a suboptimal state. This probably explains why hypertension is the most common comorbidity among Covid-19 patients, especially among those who experience the severe version of the disease.

Maintaining a healthy blood pressure (below 140/90mmHg for systolic and diastolic respectively) is important. Take these steps to control your blood pressure:

> Know your blood pressure levels. Monitor them regularly. This is important to see whether efforts to control the pressure are sufficient or should be improved.

> Limit salt intake in your diet according to daily recommendations. This can be achieved by carefully inspecting food labels for salt and sodium content, avoiding preserved and processed foods, and replacing salt with herbs and spices in cooking.

> Keep your body weight within the normal range. For overweight people, weight loss of 3% to 9% from current body weight has been shown to reduce blood pressure readings by 3mmHg to 6mmHg.

> Exercise consistently. Regular aerobic exercise, such as brisk walking and jogging, for at least 150 minutes a week is recommended as it is beneficial for the cardiovascular system and can help lower blood pressure.

> Quit smoking and avoid alcohol intake as both activities have been shown to increase blood pressure.

> Keep taking your current medications and continue to go for follow-up appointments if you are hypertensive. Be assured that the medications are safe. Do not hesitate to contact your doctor if you are in doubt about your blood pressure control or medications.

Apart from all this, hypertensive patients must seriously follow the current Covid-19 SOP and make every effort to protect yourselves from contracting the disease.

IS the coronavirus racist?

Of course not. The Covid-19 and its variants do not discriminate between race, creed or borders. They simply infect everyone indiscriminately, so the only defence is vaccines and social distancing.

But the handling of the pandemic has become intensely political along racial, class and national lines. To debate whether it should be called a China virus or an Indian variant is racist by implication. What matters urgently is how each individual, community or nation handles the pandemic. To distribute to the rich and powerful first before the poor and weak is discriminatory, but that is exactly what has happened in many countries.

The virus transmits through people. The epidemiologists suggest that minimising people travel and contacts would slow the transmission.

Those who care more about money object to shutting down the economy. Asians reacted more quickly by adopting masks and staying at home.

The West cared more about individualism and objected to masks, allowing the pandemic to get out of control.

But money and vaccines have begun to bring matters under control, except that if the coronavirus and its variants continue to spread in countries which cannot afford vaccines or can’t get enough supplies, no one is safe.

Thus, a microscopic virus has opened up the Pandora’s Box of almost all social divisions that were ignored and unaddressed. It is clear that science and technology, as well as competent organisation, plus mass cooperation would be the way to solve the pandemic.

But these three factors require trust that everyone should be protected justly.

The record so far shows that those governments which preach democracy, equality and rules-based order may be practising something rather different.

Why is it that in the United States, Pacific Islander, Latino and Black Americans have double the Covid-19 death rate than White and Asian Americans?

Israel is leading in the world vaccination rollout, and yet Palestinians have been slow to get vaccines. The UN Human Rights body has called the Israeli differential treatment of Palestinians “morally and legally unacceptable”.

Israel has illegally occupied Palestinian territory since the 1967 war, and even in the Holy Month, physically raided the Al Aqsa Mosque, sparking off the current conflict that has raged on in the middle of the pandemic.

This is not an equal fight. More than 200 Palestinians have been killed, including 64 children, versus 12 dead in Israel. More than 58,000 Palestinians in Gaza have been rendered homeless and Israelis have knocked out the only lab in the territory that processes covid tests.

An Arab-Israeli member of the Israeli Parliament has openly called the Israel action in Jerusalem as “ethnic cleansing”. The Israeli government can ignore world opinion because of the US’ strong backing.

The humanitarian crisis in Palestine is beyond a tragedy. But the Israel-Palestinian crisis shows how science and technology play a role in turning a David to a Goliath, switching the roles from victims of the Holocaust to become perpetrators of Occupation by might alone.

As geopolitical futurist George Friedman writes about “Gaza: Morality and Reality”, the moral question is extremely complex because both sides see themselves as victims.

In his geopolitical realist view, as long as Israel holds the greater military superiority, with the backing of the strongest military power of all – the United States – the conflict will not be resolved by anyone else.

This point is fully understood by the Israelis, who were scattered and not particularly powerful as a wandering people until 1947. But it was their brains and deep application of science and technology that overcame the Palestinian and Arab numerical superiority.

There are 1-2-3 options for the Israel-Palestine situation. If Israel-occupied territory were to be governed as one country, the demographics would favour the Palestinians with higher birth rates, so this solution was ruled out.

Logic suggests that perhaps a two-country solution of a separate Palestine and Israel state would be possible. The rest of the world supports this option, but the Palestinians are divided into the Fatah faction controlling the West Bank and the Hamas controlling Gaza. This creates a three-state possibility. Indeed, the greater the division between its enemies and their supporters, the more secure Israel’s position. This is classic “divide and rule” domination exercised by imperial colonials.

The Egyptian economist Samir Amin summed up this perennial Arab dilemma, commenting on the 2011 Arab Spring.

If it succeeds, then the Arab world will break out of the imperialist centre’s control. If it fails, then the Arab world will remain in “its current status as a submissive periphery, prohibiting its elevation to the rank of an active participant in shaping the world”.

Samir’s critique of Capitalism in the Age of Globalisation saw a capitalist centre comprising America, Europe and Japan, controlling a periphery of the rest.

This is achieved through five monopolies over technology, financial control, monopoly access to natural resources, media and communications, and weapons of mass destruction. The Israelis understood these perfectly and exploited them to achieve success and survival.

Thus, Israeli devotion to science and technology, military equipment, media and communications and their lobbying power playing guilt on the Eurocentric countries, ensure their dominance over the Palestinian and Arab opponents.

This is why faith or ideology alone will not control the pandemic, because it is through science and organisational power that domination continues over the weak and oppressed.

The Arab world may have physical control over much of the fossil-fuel natural resources, but as long as they remain technologically backward and divided, they will always be victims.

So, the coronavirus is not racist.

Guns do not kill people, people kill or dominate other people.

Friedman is right. Might decides geopolitical reality. For him and his ilk, morality is for the victim to complain and the victor to preach.

Those who do not learn from history will remain its victims.

Lame Indian media and politicians resort to ‘lab leak’ lie to shift focus

 

Lame Indian media and politicians resort to ‘lab leak’ lie to shift focus

India is at a critical moment of fighting the virus. Yet some Indian media outlets and politicians are still manipulating politics, slandering China with an attempt to shift contradictions away from their failed policies. India has descended into a COVID-19 mess. Indian media and politicians should bear a large part of the blame. It's a tragedy for the Indian people.

In recent days, some news channels in India have been busy spreading the groundless conspiracy theories that "the coronavirus is a bio-weapon created in a Wuhan lab." As the new wave of COVID-19 wreaks havoc on India, they have hyped up conspiracy theories and old lies cooked up by some Western media and politicians last year, baselessly accusing China of "weaponizing the virus." Some Indian media's professionalism, cognition and sense of social responsibility are really jaw-dropping.

With India caught up in the crisis and as criticisms of the Indian government's response increase, the "lab leak" conspiracy theory has attracted some new attention in India, ranging from news channels to politicians. Earlier this month, some Indian ministers and BJP leaders shared an article on Twitter. The article warned Indians not to fall into the opposition's trap of making Prime Minister Narendra Modi the scapegoat. It said, "very few are talking about China and the possibility that the virus has been unleashed to weaken India."

The "lab leak" theory has been largely discarded by the world. A World Health Organization report in late March concluded that it's "extremely unlikely" that the virus was leaked from a lab. It's really ridiculous and clumsy for some Indian media outlets to flog a dead horse. And it's easy to figure out their real purpose.

Long Xingchun, a senior research fellow with the Academy of Regional and Global Governance at the Beijing Foreign Studies University and president of the Chengdu Institute of World Affairs, said the purpose of hyping the "lab leak" theory is obvious: deflecting public attention. With no sign of abating, the raging epidemic in India has aggravated public dissatisfaction.

By hyping-up the "lab leak" theory, some Indian media outlets and politicians are attempting to divert the public's anger to China. "For countries with an electoral system like India, the top consideration for some politicians is not people's health and lives, but votes. Accusing China of unleashing the virus to weaken India provides a good excuse for India to defend its anti-epidemic response and economic downturn," Long said.

China has refuted the lies of the "lab leak" theory many times. China has strictly fulfilled its obligations under the Biological Weapons Convention and does not develop, research or produce bio-weapons.

If the Indian media and politicians are really keen on figuring out whether the virus is a bio-weapon, they should ask Washington to clarify the US' biological militarization activities inside and outside the country and to disclose the real purpose of its more than 200 biological laboratories overseas. India could also demand an international inquiry.

It looks like some Indian media outlets and politicians are resorting to the old scheme of the former Trump administration, which tried every possible means to shift the blame onto China for its failed coronavirus response.

Just have a look at the results of Trump and his failed secretary of state Mike Pompeo. They didn't focus on fighting the epidemic, but instead played tricks to politicize the virus, concocting political manipulations to discredit China. As a result, the US witnessed the highest COVID-19 death toll. This became the main reason why Trump lost the election.

Since the second wave of COVID-19 outbreak hit India, China has expressed its goodwill and taken concrete actions to provide necessary support and help to India. China has sent life-saving supplies such as ventilators, oxygen generators, masks and medicines to India. This has shown China's goodwill and humanitarianism.

However, some Indian media outlets and politicians are requiting kindness with ingratitude. They have slandered China's help, tried to play the Taiwan card, attempted to sow discord between China and neighboring countries, and devilishly spread rumors and lies to discredit China. They are shameless and have no moral bottom. What they are now doing is no different from creating a humanitarian disaster in India. It's the Indian people that will have to bear this egregious suffering.

A review of China’s Tianwen-1 Mars exploration mission

 

Tianwen-1, China’s first interplanetary expedition, has spectacularly conquered a new major milestone, with its lander-rover combination successfully soft-landing at the planned site in the southern part of a vast plain known as Utopia Planitia on Mars on early Saturday morning, Global Times learned from the China National Space Administration (CNSA).

Chinese President Xi Jinping sent warm congratulations and sincere greetings to the personnel involved in the Saturday feat.

Xi, also general secretary of the Communist Party of China Central Committee and chairman of the Central Military Commission, said in his congratulatory letter that this success marks a major step forward in the country’s interplanetary exploration, achieving a leap from Earth-moon system to the interplanetary one. Leaving the footprint of Chinese people on Mars for the first time marks another milestone of the country’s space industry development.

Xi also noted that the country will always remember the contributions and achievements of the participants of the mission, stressing that it is their courage to challenge and pursue excellence that has brought the country to a leading position in the world in terms of interplanetary exploration.

According to the CNSA, Tianwen-1 probe lowered its altitude from the Martian parking orbit around 1 am Saturday, before its lander-rover combination separated with the orbiter around 4 am. The lander-rover combination then took another flight of three hours before its entry into Mars atmosphere.

The Chinese spacecraft, after entering the Mars atmosphere, spent around nine minutes decelerating, hovering for obstacle avoidance and cushioning, before its soft landing on the designated landing site at the Utopia Planitia, CNSA said.

The orbiter rose and returned to the parking orbit 30 minutes after the separation, to provide relay communication for the landing craft combo, the Chinese space agency said.

CNSA underscored that it has conducted cooperation with a range of international aerospace organizations and countries including the Europe Space Agency, Argentina, France and Austria, throughout the implementation of its Tianwen-1 Mars mission.

The smooth landing of the Tianwen-1 probe marked that China has become the third nation that has achieved such a feat, following Russia and the US.

The successful touchdown of Tianwen-1 took place on the 295th day of its journey after it was launched and sent into planned orbit via a Long March-5 carrier rocket from Wenchang Spaceport in South China’s Hainan Province on July 23, 2020.

The whole entry, descent and landing (EDL) of Tianwen-1 took around 9 minutes, during which the speed of the craft was reduced from 20,000 kilometers per hour to zero, according to the China Academy of Space Technology (CAST) the developer of the lander-rover combo of Tianwen-1.

The EDL of the Chinese craft first involved an aerodynamic decelerating stage before it deployed parachute and variant thrust engine systems.

Such an aerodynamic decelerating stage reduced the craft's speed by some 90 percent, and then the parachute stage helped it further decelerate to some 100 meters per second before the thrust engine systems were turned on to enable the craft to enter a hovering stage as it reaches some 100 meters above the surface, said Wang Chuang, the chief director-designer of the Tianwen-1 probe with the CAST.

“At the hovering stage, the six instruments on board the rover, including microwave sensors to determine speed and distance and optical cameras, were started simultaneously in order to ‘search for a safer’ spot for the soft landing,” he explained.

Chinese space industry insiders told the Global Times on Saturday that although Tianwen-1 has inherited mature hovering and obstacle avoidance technology from the previous Chang’e-3,-4, and -5 lunar probe missions, there are still plenty of new challenges in its Mars landing attempt.

Currently, the success rate of humanity’s Mars landings is only below 50 percent, and most failed attempts happened at the EDL stage. “It took an extremely accurate operation of a range of technology, including aerodynamic shape design, parachute and engine, to achieve [the] soft landing on Mars. There is no room for defiance of even one second on any single system,” Sun Zezhou, the Tianwen-1 designer-in-chief with the CAST, noted.

Compared to the moon, Mars is first and foremost much further from Earth, which results in an inevitable communication delay of some 20 minutes. It means that Tianwen-1 is very much on its own in the landing process, CAST experts said.

Also, although the density of Mars’ atmosphere is only 1 percent of Earth’s atmosphere, it causes a more complicated environment for landing than a touchdown on the moon, as there is no atmosphere on the Earth’s closest celestial neighbor, they added.

“We did not have first-hand data on the Mars atmosphere… which means we were put in an entirely unknown environment. One can imagine the level of difficulty,” Chen Baichao, chief director-designer of the rover system with the CAST.

China has adopted a unique trajectory-elevation plan based on trim-wing design to resist the risks of uncertainty brought by the Mars atmosphere, according to the CAST.

Named after an ancient fire god of Chinese mythology, the 1.85-meter-tall and some 240-kilogram Zhurong Mars rover will then be deployed. It is designed to rove the planet for at least 3 Martian months, approximately 92 days on Earth.

In total, six scientific payloads – a pair of navigation and terrain cameras, a multispectral camera, a Mars surface composition detector, a penetrating radar, a mast-mounted magnetometer and a Mars climate station – were installed on Zhurong to study the topography, geology, soil structure, minerals and rock types and atmosphere in the area.

To survive the notoriously harsh sand storm on Mars’ surface, speed of which could reach 180 meters per second, about three times stronger than that of a super typhoon on Earth, Chinese engineers have developed a new material for Zhurong, enabling it to resist dust stains and shake off the dust, if any, by vibration.

Also, when the Mars rover encounters complicated situations on its drive path, Chinese scientists will conduct a simulation test on Earth with a 1:1 Zhurong model in the lab first, before they send instructions to the rover, Global Times learned from the CAST.

The technology used in the landing is based on China's successful human spaceflight and lunar missions, Andrew Jones, a Finland-based space observer who follows China's space industry, told the Global Times. "They haven't tested this altogether, but they have had the experience of dealing with these technologies."

What China is doing in the Tianwen-1 expedition is “extremely challenging and impressive,” said Jones.
