SINGAPORE - The number of dengue cases detected in Singapore shot up to 163 in the week of June 4 to 10, up nearly 50 per cent from the week before, when 111 cases were reported. The National Environment Agency’s (NEA) website on Wednesday showed that there were 31 active dengue clusters as at Tuesday. Of the 31, three were flagged as red alerts, or high-risk areas with 10 or more cases. A cluster at several Housing Board blocks and the Oleander Towers condominium in Toa Payoh recorded 19 cases in the past two weeks. The total number of dengue cases reported in 2023 stood at 3,595 as at last Saturday. In March, NEA warned that a dengue outbreak is likely in Singapore with the warmer months of June to August approaching, This mosquito population is transmitting the less common dengue virus serotype 3, or DenV-3, which many in the community remain susceptible to due to lack of exposure. Meanwhile, the number of Zika cases recorded here in 2023 rose to 20 as at Tuesday, NEA’s website showed. As at May 30, there were a total of 15 cases, A cluster in the Kovan area grew from 11 cases on May 30 to 15 cases on Tuesday, accounting for most of the new cases. Similar to the dengue virus, Zika is a virus transmitted by the bite of an infected Aedes mosquito, which can also carry the chikungunya virus. Those infected with the Zika virus may experience symptoms such as fever, rash and joint pain within three to 14 days of being bitten. Most Zika patients, however, do not develop sympt...

Dengue fever is considered one of the most common tropical viral infections seen in India. Dengue fever (DENG-gey) is a mosquito-borne illness that mostly affects tropical and subtropical countries. A high temperature and flu-like symptoms are common signs of dengue fever. A severe form of dengue fever, dengue hemorrhagic fever, can cause substantial bleeding, a drop in blood pressure (shock), and fatality. It commonly occurs in the post-monsoon period. Dengue is caused by 4 closely related serotypes of the dengue (Flaviviridae family) virus. It is transmitted by Aedes aegypti mosquitoes, which typically bite during day times. The incubation period ranges from 2-7 days. The spectrum of presenting complaints in Dengue infection varies from subclinical to simple fever to severe shock and multi-organ dysfunction syndrome (MODS). Book Appointment Find Our Specialists Symptoms of dengue fever generally appear four to ten days after the initial infection. They are similar to flu or other illness symptoms. Young children and persons who have never been infected may endure a less severe sickness than older children and adults.

What is dengue fever? Dengue (pronounced DEN-gee) fever is a viral disease. It is transmitted by mosquitoes mainly in tropical and subtropical areas of the world. The disease is most common in: • South Pacific • South Central Asia • Caribbean • Central and South America • Africa Dengue fever happens most often in urban areas. But it may be found in rural areas. The mosquitoes that carry the virus usually pass it on during and shortly after the rainy season. The mosquitoes are most active during the day. They are found near human dwellings, often indoors. About half of the world's population is now at risk for this disease. What causes dengue fever? Dengue fever is caused by a virus. A certain type of mosquito (Aedes) passes the virus to people through its bites. What are the symptoms of dengue fever? Dengue fever causes a severe flu-like illness. It may be look like other diseases such as the flu or malaria. The illness usually lasts 3 to 7 days. Symptoms may include: • Sudden high fever • Severe headaches • Pain behind the eyes • Joint and muscle pain • Nausea • Vomiting • Swollen glands • Rash that appears 3 to 4 days after the fever starts A very small portion of people with dengue fever get a severe case. It’s called dengue hemorrhagic fever. Symptoms show up as the fever begins to ease. These may include vomiting that does not go away, rapid breathing, blood in vomit, and bleeding gums. How is dengue fever diagnosed? A special blood test can diagnose dengue fever. It ...

The risk of contracting dengue infection has increased dramatically since the 1940s. This upward trend is due to increases in long-distance travel, population growth and urbanization, lack of sanitation, ineffective mosquito control, and increases in the surveillance and official reporting of dengue cases. Dengue has spread through Southeast Asia, the Pacific Island countries, and the Middle East. Today, approximately 40% of people live in regions of the world where there is a risk of contracting dengue. Dengue is an endemic disease, which means that it occurs regularly, in tropical regions of the world. The disease is endemic in more than one hundred countries in Africa, the Americas, Asia, the Caribbean, and the Pacific. How does dengue spread, and how is this disease transmitted to humans? The dengue virus is transmitted to humans via the bite of an infected mosquito. Only a few mosquito species are vectors for the dengue virus. What is a vector? A vector is a vehicle that carries and transmits a disease to its host organism. Vectors include animals and microorganisms that transmit different diseases. The most common vectors are arthropods, which are invertebrate animals with an external skeleton called an exoskeleton. Arthropods include mosquitoes, ticks, lice, flies, and fleas. For instance, ticks can carry Lyme disease, and some mosquitoes can carry yellow fever, malaria, and dengue fever. When a mosquito bites a person who has dengue virus in his or her blood, the m...

Peru is battling its Most of the deaths have Health authorities also said they have also fumigated millions of homes across the country in an effort to stop the infection from spreading. "We have put 1,485 thermonebulizers into operation nationwide,” said the Peruvian head of health, So far at least 200 people have died in Peru due to the outbreak, Dengue and children: What is dengue? Dengue, which is spread to humans from infected Aedes mosquitoes, can A U.S. vaccine became available just last year. According to the Centers for Disease Control and Prevention, the disease is rare in the U.S. mainland, where nearly all cases have been among travelers. When outbreaks do occur, they're typically Many people bitten by an infected mosquito may be asymptomatic, but in mild cases they may experience chills, fever, a rash and body aches that last about seven days, the CDC says. A severe infection can cause shock, internal bleeding, organ failure and death. About 1 in 20 people who get sick with dengue experience a severe case. According to the CDC, dengue is State of emergency declared On Thursday, Reuters reported Peru's The declaration came the same week as This year's spike in cases is higher than an outbreak in 2017, when there was also an El Niño, Reuters reported. El Niño is back, NOAA says. Millions of homes fumigated Over the weekend, the health ministry reported, Gutiérrez also met with Piura Governor Luis Neyra, as well as representatives from the Peruvian military and T...

Key facts • Dengue is a viral infection caused by the dengue virus (DENV), transmitted to humans through the bite of infected mosquitoes. • About half of the world's population is now at risk of dengue with an estimated 100–400 million infections occurring each year. • Dengue is found in tropical and sub-tropical climates worldwide, mostly in urban and semi-urban areas. • While many DENV infections are asymptomatic or produce only mild illness, DENV can occasionally cause more severe cases, and even death. • Prevention and control of dengue depend on vector control. There is no specific treatment for dengue/severe dengue, and early detection and access to proper medical care greatly lower fatality rates of severe dengue. Overview Dengue (break-bone fever) is a viral infection that spreads from mosquitoes to people. It is more common in tropical and subtropical climates. Most people who get dengue won’t have symptoms. But for those that do, the most common symptoms are high fever, headache, body aches, nausea and rash. Most will also get better in 1–2 weeks. Some people develop severe dengue and need care in a hospital. In severe cases, dengue can be fatal. You can lower your risk of dengue by avoiding mosquito bites especially during the day. Dengue is treated with pain medicine as there is no specific treatment currently. Symptoms Most people with dengue have mild or no symptoms and will get better in 1–2 weeks. Rarely, dengue can be severe and lead to death. If symptoms ...
