Dengue Is A Communicable Disease (2023)

FAQs

Dengue Is A Communicable Disease? ›

Dengue cannot be spread directly from person to person. However, a person infected and suffering from dengue fever can infect other mosquitoes. Humans are known to carry the infection from one country to another or from one area to another during the stage when the virus circulates and reproduces in the blood system.

How Do People Get Dengue Fever? When a mosquito bites a person who has dengue fever, the mosquito becomes infected with the virus that causes the disease. It can then spread the virus to other people by biting them. Dengue fever is not contagious, so it can't spread directly from person to person.

A mosquito becomes infected when it bites a person who has dengue in his or her blood. After about a week, the mosquito is able to spread the disease to another person when it bites. Direct spread of dengue from one person to another does not occur. Aedes aegypti mosquitoes are not found naturally in New York State.

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.

While it's rare in industrialized countries, it still affects people around the world. Typhoid fever is also extremely contagious. Read on to learn more about how it's spread and how you can protect yourself and others.

Some examples of reportable communicable disease include HIV, hepatitis A, B and C, measles, salmonella, measles, and blood-borne illnesses. Most common forms of spread include fecal-oral, food, sexual intercourse, insect bites, contact with contaminated fomites, droplets, or skin contact.

Infectivity Period (about 7 days)

Both symptomatic and asymptomatic persons are viremic and can transmit DENV to mosquitoes that bite them during this approximately 7-day period. This viremic period is known as the "period of infectivity". In sick persons, viremia typically coincides with the presence of fever.

There is no treatment for dengue, but you can help ease your symptoms by: resting. drinking plenty of fluids. taking paracetamol to help bring down your temperature and ease any pain.

How can you protect yourself from dengue? ›

Use insect repellent, wear long-sleeved shirts and long pants, and control mosquitoes inside and outside your home. Each year, an estimated 400 million people are infected with dengue virus through the bites of infected mosquitoes.

Dengue begins abruptly after a typical incubation period of 5–7 days, and the course follows 3 phases: febrile, critical, and convalescent.

This is because the Aedes mosquito breeds in water and can lay eggs even in a very small amount of water. For example, buckets, old car tyres, puddles and even bottle tops. Dengue does not spread from person to person directly.

If You Have Dengue, Protect Others

During the first week of infection, dengue virus is found in the blood of an infected person. If a mosquito bites an infected person, the mosquito becomes infected. The infected mosquito can spread the virus to other people through bites.

There is no specific medicine to treat dengue infection. If you think you may have dengue fever, you should use pain relievers with acetaminophen and avoid medicines with aspirin, which could worsen bleeding. You should also rest, drink plenty of fluids, and see your doctor.

Dengue is caused by a virus of the Flaviviridae family, Flavivirus genus, which includes viruses such as yellow fever virus, West Nile virus (WNV), and tick-borne encephalitis (TBE) virus. There are four distinct dengue viruses without cross immunity.

Dengue virus is a viral disease that is spread by mosquitoes. It is a problem in many tropical and subtropical parts of the world, including Africa, Asia, South America and some parts of northern Queensland. Estimates suggest that around 100 million cases occur each year.

Dengue is classified as (1) undifferentiated fever, (2) dengue fever (DF), and (3) dengue hemorrhagic fever (DHF). In addition to fever and at least 2 clinical findings, diagnosis of DF requires epidemiological or laboratory evidence supporting a dengue virus infection.

Dengue is caused by a virus and not by protozoa. Dengue is spread by Aedes aegypti mosquito.
