Tennessee Is Just the Latest State to Report a Hepatitis A Outbreak. Here ’s What to Know

Tennessee has joined a growing number of states battling hepatitis A outbreaks, public health officials report. The Nashville Metro Public Health Department (MPHD) announced that 14 cases of hepatitis A have been confirmed in the city since December 2017 —significantly more than the two cases it sees in an average year. MPHD is working with state public health officials to contain the outbreak, according to a statement, but the infection has already popped up in a number of nearby states, as well as some on the West Coast. Here’s what to know hepatitis A and the outbreaks around the country. What is hepatitis A? Hepatitis A is an acute viral infection that causes inflammation of the liver, resulting in symptoms such as fatigue, appetite loss, nausea, stomach pain and jaundice, according to the Centers for Disease Control and Prevention (CDC). The disease is typically spread through close contact with an infected person, or by eating or drinking contaminated food or water. Symptoms typically go away within two months, the CDC says, but patients may develop liver failure or other complications. In some cases, the disease can be fatal. Thanks to the efficacy of the hepatitis A vaccine, the CDC reports that rates of the disease have dropped by 95% since 1995 — which makes the current outbreaks somewhat unusual. Which states are experiencing hepatitis A outbreaks? At least eight states have experienced recent hepatitis A outbreaks: Tennessee, California, Indiana...

virus (HAV) is a positive-strand RNA virus that is transmitted feco-orally through person-to-person contact. Outbreaks are often linked to poor sanitation, overcrowding, or food and water contamination. Infection is often asymptomatic in children, but adults present with jaundice, abdominal pain, hepatitis, and hyperbilirubinemia. Diagnosis is through detection of immunoglobulin M antibodies against HAV, and treatment is supportive. Vaccination is the mainstay of prevention and should be given before exposure whenever possible.

By: Rachael Rettner, Senior Writer Published: 08/03/2016 06:02 PM EDT on LiveScience The coastal waters around Rio de Janeiro, where many Olympic water competitions will soon take place, are reportedly teeming with harmful viruses and bacteria. So what illnesses might people catch if they swallow some of the water? If the water has been contaminated with raw sewage, as has been reported, then a number of common pathogens could be lurking there and make people ill, experts say. “There are many types of microbes in raw sewage that have the potential to cause human disease,” said Stephen Morse, a professor of epid...

Americans who travel abroad often do not receive the recommended vaccines that would protect them from certain illnesses, new research suggests. One study of Americans visiting travel clinics found that more than half of those who were recommended to get a measles vaccination did not do so before traveling. Another study found that more than two dozen Americans were sickened with hepatitis A while visiting a resort town in Mexico in early 2015. Although the hepatitis A vaccine is recommended for people going to Mexico, none of the people who got sick in this recent outbreak were vaccinated before traveling. "...

Discussion In 1997, 150 cases of Hepatitis A (HAV) were reported in Michigan from contaminated strawberries. The strawberries were produced in Mexico and distributed to the US Department of Agriculture sponsored school lunch programs in six states. Most of the containers were not served to students and the majority of cases occurred in Michigan only. HAV is an RNA virus of the picornavirus family. The virus is spread mainly by fecal-oral contamination and contaminated food and water supplies. The incubation period is 15 to 50 days. The average is 28 days. Patients are most infectious during the one to two weeks before ons...

Hepatitis A virus (HAV) is a non-enveloped single-stranded positive sense RNA virus belonging to the Picornaviridae family. The main mode of transmission is faecal-oral, either via contaminated food products or inadequate hand hygiene. The incubation period of HAV ranges from 15-50 days. Infection with HAV in children less than five years is usually asymptomatic (80-85%), while adults can present with fever, myalgia, abdominal pain, hepatitis and jaundice (70-95%) [1]. Adults can present with fulminant hepatitis, albeit rarely, and this is associated with a high mortality, necessitating liver transplantation [2].
