Influenza viruses are most commonly transmitted to people through contact with infected pork. People who have pigs at home or in their homes can be infected with the H3N2 virus through droplets in the air that are formed when infected animals cough, sneeze, or come into contact with them. Inhaling the same infected air from pigs can cause the Influenza virus to enter your body via openings in your skin, such as your mouth, nose, ears, and eyes, or ears. This virus can also be transmitted to people who have been infected by the H3N2 virus.

How is the virus spread?

Droplets can be spread from one person to the next by infected individuals coughing, sneezing or speaking. The virus can also be spread by touching the nose or mouth of someone who has touched a surface with the virus. Flu-related complications are more common in pregnant women, children, the elderly, and people with underlying medical conditions.

What precautions should you take?

It is important to be aware that the virus attacks the respiratory system.

  • With the help of the Pulse Oximeter, you can continuously check the oxygen level.
  • A visit to the doctor should be made if the oxygen saturation level falls below 95%.
  • In severe cases, oxygen saturation levels below 90 percent may require intensive care.
  • Experts warn against self-medication in these cases

What treatment options are available?

The H3N2 influenza treatment plan includes proper rest, fluid intake, and the use of over-the-counter painkillers such as acetaminophen and ibuprofen to lower your fever. A doctor might recommend antiviral drugs like zanamivir or oseltamivir if a patient is experiencing severe symptoms.

WHO states that neuraminidase inhibitions should be administered to suspected and confirmed patients as soon as possible, ideally within 48 hours of symptom onset, in order to maximize therapeutic benefits.

Leave a comment The Indian Medical Association has, in the meantime, urged doctors not to prescribe antibiotics before confirming that the infection is bacterial. This can lead to resistance. Most cases of body aches, fever, sore throat, and cough are caused by influenza. Antibiotics are not required for these cases.
