Swine flu: symptoms, diagnosis and treatment

Incubation Period

One to seven days


Manifestations of H1N1 influenza (swine flu) are similar to those of seasonal influenza. Patients present with symptoms of acute respiratory illness, including at least two of the following

* Fever

* Cough

* Sore throat

* Body aches

* Headache

* Chills and fatigue

Diarrhea and vomiting (possible)


Influenza viruses can be directly transmitted from pigs to people and from people to pigs.
Human infection with flu viruses from pigs are most likely to occur when people are in close proximity to infected pigs, such as in pig barns and livestock exhibits housing pigs at fairs.
Human-to-human transmission of influenza A (H1N1) can also occur. At present, in India we have two indigenous cases. This is thought to occur in the same way as seasonal flu, which is mainly person-to-person transmission through coughing or sneezing by people infected with the influenza virus.

Disease spreads very quickly among the population especially in crowded places.

Cold and dry weather enables the virus to survive longer outside the body than in other conditions and, as a consequence, seasonal epidemics in temperate areas appear in winter.

People may become infected by touching / handling something contaminated with flu viruses on it and then touching their mouth or nose.

Influenza A (H1N1) viruses are not transmitted by food.

Eating properly handled and cooked pork (at an internal temparature of > 160 degree Fahrenheit) and pork products is safe.

Diagnosis of H1N1

For diagnosis of influenza A (H1N1) infection, respiratory specimen would generally need to be collected within the first four to five days of illness (when an infected person is most likely to be shedding virus). However, some persons, especially children, may shed virus for 10 days or longer.

WHO warning

India tops H1N1 death rate

With 100 deaths in 3,987 laboratory confirmed positive H1N1 cases, India has registered a mortality rate of 2.3 per cent — much above the 0.9 per cent mortality rate for the rest of the world.

Advice to parents on H1N1

The vast majority of children who develop flu-like symptoms this fall will have a few miserable days and nothing more. Those days are best spent at home -- not in the ER or a doctor's office. read more....

Docs suggest drug combo to treat H1N1

the doctors suggest use of combination of two anti-viral drugs instead of just Tamiflu to contain deterioration in the condition of critical patients. Use of double dose of Tamiflu is another option in the case of critical patients.

Ultimate guide to flu virus:

A flu virus may be 90 times smaller than a human red blood cell - so small it can hide between light waves - but in a typical year it can cause nearly half as many deaths as traffic accidents. As skilled at changing its appearance as Tom Cruise in "Mission Impossible," the flu virus mutates from one season to the next, making last year's immunizations useless in fighting this year's variation. But recent developments in the pharmaceutical industry are improving the odds on the medical battlefield. Learn more about this devious pathogen and your weapons against it .. ..

Indian vaccine for Swine Flu to be ready by March 2010:

An Indian vaccine against the pandemic strain of swine flu will be ready for use by March next with the authorities planning to fast-track clinical trials in accordance with international protocols. It was proposed to combine the different phases of clinical trials from safety to immunogenicity in the fast-track mode to make the vaccine available in March 2010, as otherwise it would be ready only by the end of 2010.
