Here’s how you can protect yourself from dengue

With the possibility of an outbreak, it’s important to understand the disease and recognise its symptoms.

The WHO on Monday warned that the Kathmandu Valley might be in for a possible dengue outbreak. According to news published in the Post, in the fiscal year 2018-2019, more than 3,425 people had been infected with the dengue virus—the highest number of infections in 15 years.

The mosquito-borne viral disease is transmitted by the female Aedes aegypti and Aedes albopictus mosquitoes. The same mosquitoes also transmit the chikungunya virus, yellow fever, and Zika virus, according to the WHO.

With the lurking threat of the possibility of the disease’s outbreak in the valley, it’s important to understand how the disease can spread, even more, to recognise the symptoms to curb the disease in its early phase. While there is no specific treatment for the illness, here are some ways that can help you keep yourself and your family alert and safe.

How does dengue spread?

Speaking to the Post about the ‘dengue outbreak’ Dr Sher Bahadur Pun from Sukraraj Tropical and Infectious Hospital said, “Mosquitoes, which spread dengue, breed in water. And sources of water, preserved or open, that is not properly maintained is one of the primary reasons for the outbreak.”

Due to an acute drinking water crisis, people in the Valley collect water in various types of containers and keep until they are used. Uncovered water tanks and discarded plastic cups and bottles could become a breeding ground for dengue-carrying mosquitoes.

The dengue mosquitoes can lay their eggs in water-filled containers inside the house and surrounding areas of dwellings. These mosquitoes are daytime biters that are found both inside and outside homes.

Pun informs that a person infected and suffering from dengue fever can infect other mosquitoes. However, dengue fever isn’t communicable and cannot spread from person to person.

Dengue symptoms

According to the WHO, the symptoms of dengue include severe muscle and joint pain, soreness in eyes, headache, constant itching and rashes. The symptoms usually last for two to seven days, following four to 10 days after a bite from an infected mosquito.

In severe cases, victims can also suffer from organ damage, severe bleeding, dehydration and even death. According to Pun, if people diagnosed with dengue are not treated on time, they can suffer from ‘dengue haemorrhagic fever’, whose symptoms include severe abdominal pain, vomiting blood, rapid breathing, bleeding gums, and feeling fatigued.

“If diagnosed early, treatments can cure the patient; however, if it crosses the warning signs, the disease may not be preventable,” said Pun.

Preventive measures

Pun recommends that patients should seek medical help on time, rest and drink plenty of fluids. As the monsoon season is at its peak, people need to keep in mind cleanliness and personal hygiene said Pun. “Hygiene is the epitome reason for such viral epidemics and avoid mosquito prone areas.”

He informs that there needs to be proper solid waste disposal and improved covered water storage practices in every household.

Apart from these measures, Pun recommends the mass to be careful about choosing the right clothing that minimises skin exposure during daylight.

“Use of generous mosquito repellents, keeping the refrigerator and toilets clean, and keep the house dry during this season can help cut down the risk of dengue,” said Pun.

Trump urges passage of defense bill with provision against troop drawdown in S. Korea

Trump has previously asked Korea to pay its fair share to keep US troops on the peninsula. US President Donald Trump on Wednesday urged Congress to pass a defense bill containing a provision restricting the drawdown of American troops in South Korea. On Monday, the House and Senate Armed Services Committees agreed on the final version of the National Defense Authorization Act for Fiscal Year 2020, which authorizes funding for the Department of Defense. According to the accompanying conference report, the new bill restricts the use of funds for removing troops from South Korea, an issue that has drawn intense scrutiny amid contentious cost-sharing negotiations between Seoul and Washington.

Pompeo says US is hopeful N. Korea will refrain from nuclear, long-range missile tests

Both sides are hopeful of continued talks. The United States is hopeful North Korea will continue to refrain from nuclear tests and long-range missile tests, US Secretary of State Mike Pompeo said Tuesday, after Pyongyang said it had conducted a “very important” test over the weekend. North Korea said the test occurred at its Dongchang-ri satellite launch site on Saturday, raising tensions ahead of a year-end deadline North Korean leader Kim Jong-un has imposed for the US to show flexibility in their negotiations on dismantling Pyongyang’s nuclear weapons program. “Chairman Kim personally made the commitment to denuclearize, said there wouldn’t be long-range missile tests, nuclear tests,” Pompeo said at a joint press conference with Russian Foreign Minister Sergey Lavrov at the State Department.

Myanmar running out of time to cope with climate change, warns historian Thant Myint-U

Myanmar is one of the most vulnerable countries in the world to the effects of climate change and is grossly unprepared to deal with the consequences. WASHINGTON – Myanmar is one of the most vulnerable countries in the world to the effects of climate change, and is grossly unprepared to deal with the consequences, warns historian Dr Thant Myint-U. The Myanmar historian, author and conservationist was in the United States recently to speak on his most recent book examining race, capitalism and the crisis of democracy in Myanmar titled “The Hidden History of Burma”. In an interview for the online video and podcast Asian Insider, Dr Thant told The Straits Times the threat of climate change tipped his ledger towards pessimism about the country’s future. “I think whatever we think of the ledger in general, perhaps it comes to 50/50,” he said. “When you add on

Hundreds of thousands take part in massive Hong Kong march

Police seized a gun and bullets which they believed were intended to be used during the demonstration. HONG KONG – Hundreds of thousands braved the chilly weather in Hong Kong to join a massive and largely peaceful march on Sunday afternoon (Dec 8) hours after police, in a crackdown on the main island, seized a gun and bullets which they believed were intended to be used during the demonstration. Sunday’s march to mark Human Rights Day drew a crowd of 800,000, said the Civil Human Rights Front, the organiser behind the biggest protests in the city. The event was a sign of the level of support for the anti-government movement that has stretched for more than six months. The march, which began around 3pm, went on smoothly but tensions notched up at night when hundreds of protesters in face masks and helmets started building barricades in areas such as Central and Causeway Bay to slow down

Rohingya Crisis Fallout

Transparency International Bangladesh has painted a grim outlook for the crisis. Bangladesh faces long-term financial, political and security challenges as Rohingya repatriation may not happen anytime soon, said Transparency International Bangladesh (TIB) Executive Director Dr Iftekharuzzaman. The fund from the international community for nearly one million Rohingyas may not sustain as no strong international initiative has been taken to oblige Myanmar for creating a conducive environment for the refugees to return soon, he said. “As a result, Bangladesh’s socio-economic instability will grow. There are risks of security at local and national levels. The crisis also creates political and diplomatic challenges for the government,” Iftekharuzzaman said. It also involves the risks of growing extremism as the people who face violence are more likely to become violent, he said at a press confere
