Antiviral drugs can suppress the virus and reduce the severity and length of the symptoms, but cannot remove the virus from your body. HIV is transmitted by sexual contact, blood transfusion, contaminated needles and during delivery of a newborn.
Practising safe sex, screening for the virus during blood donation and avoiding needle-sharing among drug addicts are among the ways to prevent HIV infection.
In some, the infection persists and results in warts or pre-cancerous lesions that can lead to cancer of the cervix, vulva, vagina, mouth or throat. There is no treatment for an HPV infection, but there are vaccines to prevent infections by the most common types of this virus. This virus is transmitted through contact with droplets from an infected person when they cough or sneeze. It causes mumps. Symptoms include swollen and tender salivary or parotid glands, difficulty chewing, fever, headache, muscle aches and loss of appetite.
This virus usually causes infections in animals, but one type, parvovirus B19, only infects humans. Parvovirus B19 is highly infectious and spreads through contact with droplets from an infected person when they cough or sneeze. This virus is transmitted via the faecal-oral route, meaning that the virus enters the body through the ingestion of infected faecal matter. Initial symptoms of polio include fever, fatigue, headache, vomiting, stiffness in the neck and pain in the limbs.
Supportive treatments such as bed rest, pain control, good nutrition and physical therapy to prevent deformities from occurring over time, can help reduce the long-term symptoms due to muscle loss.
This virus usually infects domestic and wild animals, and is spread to humans through saliva when an infected animal bites them. Initially, non-specific symptoms such as fever, sore throat, malaise, headache, nausea and vomiting will occur. There may be discomfort or a prickling or itching sensation at the site of bite, progressing within days to symptoms of cerebral dysfunction, anxiety, confusion and agitation. As the disease progresses, the person may experience delirium, abnormal behaviour, hallucinations and insomnia.
An irrational fear of water hydrophobia and of fresh air aerophobia are unique signs of rabies infection in humans. Antiviral treatment is not effective, but it is possible to prevent rabies by quickly treating the wound and administering human rabies immunoglobulin, as well as the rabies vaccine. A pet dog gets vaccinated against rabies in Kuching in this filepic, when the rabies outbreak in the state of Sarawak first began.
The rabies virus can pass from an infected animal to a human through its saliva, usually via a bite. It causes viral gastroenteritis, with acute onset of vomiting and diarrhoea that lasts between four to seven days. There is no cure for this disease; treatment is supportive and consists of fluid and salt replacement either orally or intravenously.
A rash may start on the face and spread to the rest of the body. Fever, sore throat and fatigue may also occur. Each of these has its own symptoms ranging from jaundice, low immunity and cirrhosis. It can be contracted through sexual contact and through blood. There are a variety of treatments available including antiviral vaccines.
Caused by the sexually transmitted herpes simplex virus HSV , it affects the genitals, mouth and face. The affected areas include the buttocks and anal areas. Newborn babies and people with lower immunity are more vulnerable to this virus. It comes in two types; the genital and oral virus. In some cases, it does not show any symptoms, but in other cases it is represented by itchy painful blisters. It is spread via direct contact and can be treated through medical treatment.
Characterized by cough, running nose, fever, inflamed eyes, and reddish skin rash, measles is caused a virus. Also referred to as rubeola, this disease is quite fatal in small children below 5 years. It is a children's infection that can be prevented by a vaccine. Also known as the stomach flu, its signs include watery diarrhea, nausea, vomiting, abdominal crumbs, and fever. This is an intestinal infection spread through bodily contact and infected food or water.
Like all other viral infections, it has no sure treatment hence preventive measures should be observed. Children, the aged, and lower immune persons are more susceptible to infection.
Proper hand washing routine and food preparation hygiene are effective ways to prevent this disease. The pneumonia virus affects the lungs causing them to swell and become irritated.
Its symptoms feature coughs, shortness of breath, fever, and shaking chills. This disease can be treated by preventing dehydration by increasing the consumption of beverages rich in salts and minerals. Dengue disease is named after the virus that causes it dengue. It is one of the most common viral diseases in the world, infecting more than million people annually. Like yellow fever, it is transmitted through the bite of the Aedes Aegypti fly.
It feeds on the blood of a person infected and then passes the virus to a healthy person through his sting. The Aedes Aegypti fly reproduces in places where there is stagnant water, depositing its eggs in the walls or edges of these wells of water. The virus can also be transmitted by consuming water contaminated with the eggs of the fly.
Among the most common symptoms of dengue are lymph node growth, severe muscle pain, fever, joint pain and the occasional appearance of skin rashes. Like other viral diseases, dengue can be prevented by administering a single-dose vaccine in patients between 0 and 12 months of age. This disease gets its name from the virus that causes it the yellow fever virus. It is more common to find patients infected with this virus in continents such as Africa, South America and Central America including the Caribbean islands.
Its spread occurs through the bite of a mosquito known as Aedes Aegypti, Aedes Sabethes or Aedes Haemagogus, which feeds on the blood of the person infected with the virus and then transmits it to other healthy people through its sting Liboreiro, Symptoms such as nose and mouth bleeding, yellow pigmentation of the skin, vomiting of dark color, cardiac arrhythmia, dehydration and high fever may appear in people with this type of virus. It is a disease that can be prevented by vaccination.
Such vaccination must take place between the ages of 9 and 60 years and must be applied again every 10 years. Influenza is one of the most common viral diseases in humans. This occurs when the RNA virus lodges and reproduces in the cells of the body. It usually affects the respiratory tract, and is often mistaken for a cold during the first stage of development.
The most common symptoms of this disease are headache, fever, malaise, body weakness, dry cough, vomiting, diarrhea and sore throat. It is important to note that the RNA virus is transmitted by air, through small particles of fluid that come off when coughing, talking or sneezing. This disease can be prevented by the application of influenza vaccines. These vaccines usually protect patients from different types of flu, including swine H1N1. Chickenpox is an infectious disease that occurs when the body's cells acquire a virus known as varicella zoster.
It is a disease commonly acquired by individuals under 15 years of age. However, it can also be transmitted to children over 15 and to adults. Viral rashes can affect children and adults alike.
