As the coronavirus infects more people around the world, conservationists are warning of the risk to another vulnerable species: Africa’s endangered mountain gorilla.
Congo’s Virunga National Park, home to about one-third of the world’s mountain gorillas, is barring visitors until June 1, citing “advice from scientific experts indicating that primates, including mountain gorillas, are likely susceptible to complications arising from the COVID-19 virus.”
Neighboring Rwanda is also temporarily shutting down tourism and research activities in three national parks that are home to primates such as gorillas and chimpanzees.
Mountain gorillas are prone to some respiratory illnesses that afflict humans. A common cold can kill a gorilla, according to the World Wide Fund for Nature, one reason tourists tracking gorillas are not normally permitted to get too close.
About 1,000 mountain gorillas live in protected areas in the Democratic Republic of the Congo, Uganda and Rwanda, for whom tourism is an important source of revenue.
However, the COVID-19 pandemic has led to restrictive measures.
Virunga National Park’s decision has been welcomed by conservationists in the region.
Paula Kahumbu, chief executive of the Kenya-based conservation group WildlifeDirect, told reporters that “every possible effort must be made” to protect mountain gorillas, because so few are left in the wild.
“We know that gorillas are very sensitive to human diseases,” she said. “If anyone has a cold or a flu they are not allowed to go and see the gorillas. With coronavirus having such a long time of no symptoms in some cases, it means that we could actually put those gorillas at risk.”
Even existing measures might not be enough to protect them.
Gladys Kalema-Zikusoka, an Ugandan conservationist with Conservation Through Public Health, said that a study published this year by her group and Ohio University showed that measures in place to protect gorillas from humans are not effective in practice.
The rule on keeping a safe distance from the gorillas was broken almost every time a group of tourists visited, she said.
“What the research found is that the seven-meter rule was broken almost all the time ... like 98 percent of the time,” she said. “But what was interesting is that 60 percent of the time it was tourists that broke it and 40 percent of the time it was the gorillas who broke it.”
If close interaction cannot be prevented, one measure that could potentially improve safety is requiring tourists to wear masks at all times, she said.
Uganda has not announced a shutdown of gorilla tourism, although tourist traffic from Europe and elsewhere has dwindled.
The decision on whether to shut down gorilla tourism is now academic, as there is almost no business amid the outbreak, Uganda Wildlife Authority spokesman Bashir Hangi said.
Still, the few tourists who come are screened for fever and other symptoms, and must obey rules such as not standing within 7m of a gorilla family, he said.
Visitors from virus-affected countries who have gone through quarantine in Uganda need to produce what he called a certificate of isolation before they are permitted to track the gorillas.
Amos Wekesa, whose Great Lakes Safaris organizes gorilla tours in Rwanda and Uganda, spoke mournfully of “hardly any business” as tourists postpone visits or seek refunds.
The region’s mountain gorilla population dropped sharply in the past century because of poaching, illness and human encroachment. Mountain gorillas have been listed as critically endangered or endangered since 1996, although their numbers are now said to be growing as a result of conservation efforts.
However, there have been painful losses. Some gorillas die of natural causes, falling from trees or being killed in fights between males for territory or dominance. A lightning strike last month killed four mountain gorillas.
In Rwanda, where tourism is the top foreign-exchange earner, the government has prioritized the protection of gorillas, even launching a naming ceremony for baby primates.
Tourism revenue is key in protecting mountain gorillas, as authorities can use some of the money to help local communities or invest in anti-poaching activities.
A gorilla-tracking permit costs up to US$600 in Uganda and thousands of tourists pay each year.
A similar permit costs more than US$1,000 in Rwanda.
A coronavirus-free tropical island nestled in the northern Pacific might seem the perfect place to ride out a pandemic, but residents on Palau said that life right now is far from idyllic. The microstate of 18,000 people is among a dwindling number of places on Earth that still report zero cases of COVID-19 as figures mount daily elsewhere. The disparate group also includes Samoa, Turkmenistan, North Korea and bases on the frozen continent of Antarctica. A dot in the ocean hundreds of kilometers from its nearest neighbors, Palau is surrounded by the vast Pacific Ocean, which has acted as a buffer against the
Dutch scientists have found the coronavirus in a city’s wastewater before COVID-19 cases were reported, demonstrating a novel early warning system for the disease. SARS-CoV-2 — the virus that causes COVID-19 — is often excreted in an infected person’s stool. Although it is unlikely that sewage will become an important route of transmission, the pathogen’s increasing circulation in communities would increase the amount of it flowing into sewer systems, Gertjan Medema and colleagues at the KWR Water Research Institute in Nieuwegein said on Monday. They detected genetic material from the coronavirus at a wastewater treatment plant in Amersfoort on March 5, before
TRUE TOLL? Some Chinese are skeptical about official data, particularly given the overwhelmed medical system and initial attempts to cover up the outbreak The long lines and stacks of urns greeting family members of the dead at funeral homes in Wuhan, China, are spurring questions about the true scale of casualties at the epicenter of the COVID-19 outbreak, renewing pressure on a Chinese government struggling to control its containment narrative. The families of those who succumbed to the coronavirus in the city, where the disease first emerged, were allowed to pick up their cremated ashes at eight funeral homes last week. As they did, photographs circulated on Chinese social media of thousands of urns being ferried in. Outside one funeral home, trucks shipped in about 2,500
KEEN INTEREST: India is trying to procure medical gear from domestic producers and abroad, and China has emerged as a possible supplier as its factories reopen India is to buy ventilators and masks from China to help it deal with COVID-19, a government official said yesterday, even though some countries in Europe had complained about the quality of the equipment. India has recorded 1,251 cases of the coronavirus, with 32 deaths, but health experts said the country of 1.3 billion people could see a major surge in cases that could overwhelm its weak public health system. Indian Prime Minister Narendra Modi’s government said that it was trying to procure medical gear, including masks and body coveralls, both from domestic firms and from countries such as South Korea and
