Nepal fears over 60,000 people could get infected with dengue in next three months
KATHMANDU – The number of dengue-infected patients visiting hospitals in the Kathmandu Valley has been gradually rising recently, and this could be just the beginning.
Experts warn that a sharp spike in cases is likely once the ongoing rainfall stops for a few days.
In the worst-case scenario, over 60,000 people could get infected with the dengue virus in the next three months, according to a projection prepared by the Epidemiology and Disease Control Division.
The division, which is responsible for the epidemic and outbreak control in the country, said that the figure is just an estimate, which is made for the preparation for possible worst-case scenarios.
'Every year, we made a projection of the worst-case scenario, which is required for internal preparedness,' said Dr Chandra Bhal Jha, director at the division. 'Our projection does not mean the estimated number of people will be infected with the deadly virus. The infection number depends on the measures we take to lessen the risks.'
Dengue is a viral disease transmitted by female Aedes aegypti and Aedes albopictus mosquitoes. According to the World Health Organisation, the same vector also transmits chikungunya, yellow fever, and the Zika virus.
Since January, 1,673 people from 73 districts have tested positive for the dengue virus. The deadly virus has not yet been reported in four out of 21 mountain districts—Rasuwa of Bagmati province, Manang of Gandaki province, and Humla and Dolpa of Karnali province.
In 2024, 15 people died, and 41,865 others were infected as the virus spread to 76 districts. In 2023, 88 persons died and more than 54,000 were infected by the virus, which had spread to all 77 districts. At the time, hospitals in Kathmandu Valley were overwhelmed with dengue patients, and pharmacies had run out of paracetamol, the most widely used medicine to treat fever.
Experts say reported cases may represent only a small fraction of the true scale of infection, as around 90 percent of the infected people are asymptomatic, and many deaths and infections often go unreported.
Many people infected with dengue show mild symptoms, which do not need any treatment or can be managed with paracetamol at home.
Since dengue became endemic in Nepal years ago, meaning people get infected throughout the year, health officials no longer classify it as an outbreak of a deadly virus.
Officials at the division said that they have alerted all concerned health agencies about the looming crisis, supplied testing kits, and allocated a budget to carry out a dengue search-and-destroy drive.
'We have already sent Rs 80 million to local levels to carry out the dengue search and destroy drive,'said Jha. 'Health workers and health facilities are asked for necessary preparation as the disease could break out at any time. We have also requested help from other sectors and the general public to destroy dengue breeding grounds. '
Officials say an outbreak could occur in any place at any time, as most districts across the country have reported dengue cases.
Experts say that instead of counting the number of infected people, concerned authorities must focus on implementing mitigating measures.
Experts warn that the rising temperatures, coupled with monsoon rainfall, create the perfect environment for dengue-spreading vectors to breed. They say that unless the general public is made aware of the problem and takes it seriously, the spread of the dengue virus will not lessen. They asked the authorities concerned to learn from past experiences while taking preventive measures.
'Focus should be made on behavioural change, which needs continuous efforts and investments,' said Dr Sher Bahadur Pun, chief of the Clinical Research Unit at Sukraraj Tropical and Infectious Disease Hospital. 'Breeding grounds of dengue-spreading mosquitoes could be anywhere, including schools, hospitals, private houses and others, and without the participation of the general public in dengue control efforts, we cannot expect control of infection of the deadly disease.'
Doctors say along with launching a search-and-destroy drive on a regular basis, authorities should also focus on strengthening the capacity of health facilities to prevent them from being overwhelmed in the event of a possible massive outbreak, experts say.
Dengue-transmitting mosquitoes breed in clean water and bite people in daylight. Uncovered water tanks and discarded objects such as plastic cups and bottles could be breeding grounds for dengue-carrying mosquitoes.
According to doctors, mild to high fever, severe muscle pain, rashes, severe headache and pain in the eyes are some symptoms of dengue. Doctors advise those with these symptoms to seek immediate treatment. While there is no specific cure for the disease, early detection and access to proper medical care can lower fatalities.
Nepal reported its first dengue case in a foreigner in 2004 in Chitwan district. Since then, an increasing number of dengue infections, including major outbreaks, have been reported from many districts.
The World Health Organisation says there is no specific cure for severe dengue, but early detection and access to proper medical care can save lives.

WHO pushes countries to raise prices on sugary drinks, alcohol and tobacco by 50%
Sign up now: Get ST's newsletters delivered to your inbox It is the first time the World Health Organisation has suggested a target price rise for sugary drinks, alcohol and tobacco. LONDON - The World Health Organisation is pushing countries to raise the prices of sugary drinks, alcohol and tobacco by 50 per cent over the next 10 years through taxation, its strongest backing yet for taxes to help tackle chronic public health problems. The United Nations health agency said the move would help cut consumption of the products, which contribute to diseases like diabetes and some cancers, as well as raising money at a time when development aid is shrinking and public debt rising. 'Health taxes are one of the most efficient tools we have,' said Dr Jeremy Farrar, WHO's assistant-director general of health promotion and disease prevention and control. 'It's time to act.' The WHO launched the push, which it is called '3 by 35' at the UN Finance for Development conference in Seville. WHO said that its tax initiative could raise US$1 trillion (S$1.2 trillion) by 2035 based on evidence from health taxes in countries such as Colombia and South Africa. The WHO has backed tobacco taxes and price rises for decades, and has called for taxes on alcohol and sugary drinks in recent years, but this is the first time it has suggested a target price rise for all three products. WHO director-general Tedros Adhanom Ghebreyesus told the conference that the taxes could help governments 'adjust to the new reality' and bolster their own health systems with the money raised. Many low and middle-income countries are coping with cuts to aid spending led by the United States, which is not attending the Seville conference. The US is also in the process of withdrawing from the WHO. From $4 to $10 As an example, the initiative would mean a government in a middle-income country raising taxes on the product to push the price up from US$4 today to US$10 by 2035, taking into account inflation, said WHO health economist Guillermo Sandoval. Nearly 140 countries had already raised tobacco taxes and therefore prices by over 50 per cent on average between 2012 and 2022, the WHO added. Mr Sandoval said the WHO was also considering broader taxation recommendations, including on ultra-processed food, after the agency finalises its definition of that type of food in the coming months. But he added that the agency expected pushback from the industries involved. The initiative is also backed by Bloomberg Philanthropies, the World Bank and the Organisation for Economic Co-operation and Development (OECD), and involves support for countries who want to take action.

Mental health problems growing among new mums in Nepal
July 1, 2025 KATHMANDU – A few weeks ago, a 26-year-old working class mother was rushed to the Thapathali-based Paropakar Maternity and Women's Hospital, as she suffered from persistent sadness, sleeplessness, and loss of interest in everything including her newborn. Doctors attending the patient identified that the woman was suffering from postpartum depression developed after the child birth. 'We prescribed anti-depressants to the patients, as she was suffering from anxiety and depression, which are serious mental health problems,' said Dr Pratikshya Ghimire, a psychiatrist at the hospital. 'The patient is recuperating now, as her family members and in-laws were supportive.' Every day, doctors at the maternity hospital refer to over half a dozen pregnant or postnatal women seeking care at the hospital for psychiatric and psychological counseling. Of those referred, the number of working class women is significant. However, not all women suffering from prenatal depression (depression during pregnancy) and postpartum depression (depression after child birth) get proper treatment like the woman mentioned above, as most birthing centers throughout the country lack mental health screening services. 'Health workers including physicians may ask pregnant and postnatal women they suspect have mental health issues for seeking psychiatric or psychological help, but all may not be able to afford,' said Ghimire. 'Thousands of women would benefit if mental health services were made available in maternity hospitals.' Studies show that working mothers are at greater risk for postpartum depression. Mental health problems during pregnancy are the second leading cause of maternal deaths, after excessive bleeding during childbirth, also known as postpartum haemorrhage, and pre-eclampsia (pregnancy-related high blood pressure disorders). A report on maternal mortality unveiled in 2022 by the National Statistics Office showed that six percent of maternal deaths were due to self-harm (suicide), with most cases occurring during pregnancy. To address mental health problems during pregnancy, the Ministry of Health and Population started outpatient care services at the Maternity Hospital in October last year with the help of the World Health Organisation. Health Officials had planned to expand such services to at least one hospital in each province. 'But due to the budget constraints, we could not expand the services this year,' said Dr Phadindra Baral, chief of the Mental Health Section at the Epidemiology and Disease Control Division. 'We are aware that the service is essential and thousands of pregnant and postnatal women throughout the country will be benefitted if we provide it.' Doctors say mental health problems in pregnant women and new mothers are more severe than previously believed, with around 20 percent women affected. They say prenatal and postnatal depression can occur at any time during pregnancy or after childbirth. Shifts in hormone levels during pregnancy and after childbirth can significantly affect mood. Many women feel anxious about changes happening to their bodies. Some may even have financial concerns and some worry about taking on new and additional responsibilities. Some women experience extreme sadness, anxiety, fatigue, and changes in sleeping and eating habits during pregnancy or after childbirth. Experts warn that prenatal and postnatal depression along with anxiety and other mental health issues, can lead some women to take their own lives. In the case mentioned above, the woman worried excessively about her job, career, and future of the baby. She feared that she could not resume her job again, which not only increased her family's financial troubles but also affected her career and the future of her newborn. After treatment, her condition is getting better every day. 'We will adjust doses of her medicines in the coming days,' said Ghimire. Health officials hope that screening pregnant women for mental health problems and providing prompt treatment will help reduce maternal deaths, which have been rising alarmingly of late. Nepal reduced the maternal mortality rate from 539 per 100,000 births in 1996 to 239 per 100,000 births in 2016. For this, the country also received a Millennium Development Goals award. The 2021 census report showed that in every 100,000 live births, 151 women died from maternity-related complications. A recent report by the UN health body shows that Nepal has reduced maternal deaths by over 70 percent since 2000. The UN health body, in its report stated that currently 142 Nepali women die from maternity-related complications per 100,0000 live births. Nepal's target under the UN's Sustainable Development Goals is to reduce the maternal mortality rate to 75 per 100,000 births by 2030.
