Write 5 communicable disease its cause and remedy
Answers
1. Common Cold
As their name suggests, common colds are extremely common. According to the Centers for Disease Control and Prevention (CDC), adults have an average of 2 to 3 colds each year and children usually have even more. A runny or stuffy nose, sore throat, coughing and sneezing are typical symptoms. Tiredness, a slight fever and headaches may also occur.
Common colds are caused by viruses. Rhinoviruses are the most common cause, but more than 200 viruses can be responsible. The common cold is usually spread through water droplets containing the virus, which are made in the person's respiratory tract and then released into the air by sneezing, coughing or simply breathing.
Another person can then catch the cold by breathing in the droplets or by touching a surface where the droplets land. There is no cure for the common cold. The infection generally worsens for a few days, then resolves on its own in 1 to 2 weeks.
2. Influenza (The Flu)
The flu is similar to the common cold but is usually more severe. In addition to typical cold symptoms, the flu often produces muscle aches and a high fever. Coughing, headaches and tiredness are usually more severe than with a cold. Symptoms tend to appear suddenly with the flu and more gradually with a cold.
The flu is caused by influenza viruses, usually influenza A or influenza B. These viruses are transferred from person to person in the same way as the common cold. People are contagious from 1 day before symptoms appear and for up to 1 week afterwards.
Three antiviral medications are available to treat influenza — oseltamivir (Tamiflu), zanamivir (Relenza) and peramavir (Rapivab). They can reduce the severity of symptoms and shorten the illness by 1 to 2 days and are most effective when started in the first 2 days of symptoms.
3. Strep Throat
Strep throat is another disease similar to the common cold, but a sore throat is the most prominent symptom. Strep throat usually causes a moderate to high fever. The tonsils become red and swollen and may have white spots on their surface.
A bacterium called group A Streptococcus causes strep throat_._ This bacterium is spread in a manner similar to the common cold. A rapid strep test — requiring a simple swab of the back of the throat — is used to diagnose strep throat. Antibiotics, such as penicillin, will shorten the duration of the infection. People with strep throat remain contagious until their fever is gone and they have been on antibiotics for at least 1 day.
4. Fifth Disease
Fifth disease is similar to the common cold — producing a runny nose, slight fever and headache — but it also causes a rash. The first rash is characterized by bright red cheeks, hence the name "slapped cheek" rash. This rash usually appears a few days after the cold symptoms begin. As it begins to fade, a second red rash typically appears elsewhere on the body. In some adults, fifth disease produces only painful joints. Fifth disease is more common in children than in adults.
Also known as erythema infectiosum, fifth disease is caused by a virus called parvovirus B19. This virus is passed from one person to another in the same way as the common cold. An infected person is contagious in the early stages of the illness and is usually no longer contagious by the time the first rash appears. There is no cure for fifth disease. It usually resolves in 5 to 10 days, although the second rash may come and go for several weeks.
5. Gastroenteritis
Gastroenteritis — commonly called the stomach flu — is characterized by diarrhea, nausea, vomiting and abdominal pain. A fever may be present as well. Dehydration can be a concern, especially in young children.
Norovirus is the most common cause of gastroenteritis in the United States, according to the Merck Manual. Rotavirus is another cause, especially in young children.
The virus is spread by the stool. People become infected when they directly touch the stool of an infected person or when they consume food or water contaminated by virus-containing stool. There is no cure for viral gastroenteritis. It resolves on its own in 1 to 2 days or up to 10 days, depending on the virus.
