Infectious diseases are classified into many types, of which group A infectious diseases are especially dangerous. If not detected and effectively isolated, group A infectious diseases will cause severe consequences such as outbreaks into epidemics.

1. What is a group A infectious disease?

Infectious disease is a disease that is transmitted directly or indirectly from person to person or from animal to person, caused by an infectious disease agent. Infectious pathogens can be viruses, bacteria, parasites, and fungi.
Group A infectious diseases are particularly dangerous diseases with the ability to spread very quickly and spread widely, with high mortality rates or unknown pathogens.

2. The list of infectious diseases group A includes which diseases?

Group A infectious diseases include:
Polio This is an acute viral infection, transmitted by the gastrointestinal tract, caused by the Polio virus and can be infectious. Polio is identified through the manifestation of acute flaccid syndrome.

Influenza A-H5N1 Influenza A-H5N1 is a particularly dangerous infectious disease, caused by influenza type A virus, strain H5N1, family Orthomyxoviridae. The first and easiest route of infection is by direct contact with infected poultry and the waste of infected or healthy poultry carrying the virus.

Plague This is an acute infectious disease, caused by the bacillus Yersinia pestis, plague transmitted mainly by blood (by flea bites). The clinical picture is a state of infection, severe systemic toxicity.
Smallpox According to statistics of the World Health Organization (WHO), from 1978 to now smallpox has not appeared and will not return.

Ebola, Marburg or Lassa hemorrhagic fever These group A infectious diseases carry a high risk of death.
West Nile fever (Nile) West Nile virus usually lives in the body of wild birds. This virus is dangerous in that it can be easily transmitted to humans through the vectors of mosquitoes. No one knows the symptoms of illness when infected with this virus. The course of the disease is just like a normal fever, then a high fever, a ban on speech, and then slowly going into a coma...

Yellow fever Yellow fever is caused by a virus of the Flaviviridae family. The disease is transmitted from person to person mainly by Aedes aegypti mosquito infected with the virus and biting healthy people. These mosquitoes are also vectors of dengue fever and Zika disease.
Cholera Cholera is an acute infectious disease. Cholera is usually caused by the bacterium Vibrio cholerae and is transmitted through the gastrointestinal tract with loose stools and profuse vomiting. Cholera rapidly leads to dehydration - electrolytes, cardiovascular collapse, exhaustion and death if not treated early.
Severe acute respiratory disease (viral) COVID 19 Acute respiratory infection caused by nCoV (new strain of Corona virus) COVID 19 is also a form of severe acute respiratory infection caused by a virus.

New and emerging dangerous infectious diseases and unknown pathogens The situation of infectious diseases in the world and in Vietnam has been increasing since the 1970s. Many emerging infectious diseases have appeared with a frequency of more than one disease every year.

3. Prevention of Group A infectious diseases

Specific prevention of group A infectious diseases with vaccines (if available). Currently, there are vaccines to prevent some bacterial and viral diseases such as polio vaccine.
We need to pay attention to personal hygiene, wash hands frequently, eat cooked food and drink, clean living environment indoors and out.
